NEW QUESTION # 35
An engineer is designing a wireless solution for a corporate campus which includes two primary buildings:
Research and Operations. The design must ensure seamless mobility for employees moving between buildings, support uninterrupted connectivity for real-time applications, and facilitate efficient Layer 2 and Layer 3 roaming. Each building ' s 9800-80 WLC manages its local APs, and the solution must support 802.11 r/k/v while maintaining an effective mobility control plane. Which design approach leverages Cisco mobility group architecture to meet the requirements?

• A. Establish the Operations building ' s WLC as an anchor controller, configuring the Research building ' s WLC to tunnel all client traffic to it for centralized traffic management.
• B. Add both 9800-80 WLCs in a single mobility group with no specific roles assigned, enabling peer-to- peer coordination for seamless roaming across buildings.
• C. Assign each 9800-80 WLC to separate mobility groups, one for each building, to isolate traffic and mitigate the risk of overloading a single mobility group.
• D. Designate the Research building ' s WLC as the primary controller and the Operations building ' s WLC as a secondary controller within a single mobility group to centralize mobility management.

Answer: B

Explanation:
Cisco ' s mobility group architecture enables seamless client roaming between WLCs by establishing a trusted peer relationship and shared mobility domain. When two Cisco Catalyst 9800-80 WLCs are placed in the same mobility group, they establish CAPWAP mobility tunnels enabling both Layer 2 and Layer 3 roaming with session continuity including IP address preservation. Within the same mobility group, WLCs exchange client state information, allowing 802.11r Fast BSS Transition, 802.11k neighbor reports, and 802.11v BSS Transition Management to function across controller boundaries. No specific primary or secondary roles are assigned within a mobility group - all members are peers with equal standing for roaming purposes, which is precisely what Option D describes. Option A incorrectly implies a hierarchical structure that does not exist in mobility group peer relationships. Option B separating the WLCs into different groups would break inter- building roaming since clients would experience a full re-authentication cycle. Option C imposing an anchor relationship is appropriate only for guest WLANs. Reference: WLSD Study Guide - Mobility Group Architecture, Inter-Controller Roaming, 802.11r/k/v Fast Roaming Design.

NEW QUESTION # 36
A wireless engineer is getting ready to perform a predictive site survey. The new network needs to support data and voice over wireless. Which two Cisco recommendations should be considered for the design?
(Choose two.)

• A. Set -19 dBm of separation between APs on the same channel.
• B. Use the 5 GHz radio band due to the 24 non-overlapping channels.
• C. Use the 5 GHz radio band due to 40 MHz bandwidth capability.
• D. Set the cell overlap to 15%
• E. Set the cell boundary to -67 dBm.

Answer: C,E

Explanation:
For a network supporting both data and voice over wireless, two key Cisco design recommendations apply.
First, the 5 GHz radio band is recommended for voice over wireless due to its wider channel bandwidths, allowing for higher data rates and better quality of service for latency-sensitive applications. 40 MHz channels in the 5 GHz band provide significantly higher throughput than 20 MHz channels in 2.4 GHz, making Option B correct for the bandwidth reason stated. Second, setting the cell boundary to -67 dBm ensures sufficient signal strength for reliable voice communication at the cell edge, which is the Cisco standard threshold for VoWLAN coverage. Options C and E are partially correct (24 non-overlapping channels is accurate, 15-20% overlap is standard) but B and D are the primary Cisco recommendations that define the design targets for a predictive survey supporting voice. Reference: WLSD Study Guide - VoWLAN Design Requirements, Predictive Survey Design Criteria, 5 GHz Band Selection.

NEW QUESTION # 37
Which issue occurs when wireless access points transmit by using the highest power level in a building that has brick walls?

• A. hidden node
• B. reflection
• C. wideband interference
• D. narrowband interference

Answer: A

Explanation:
The hidden node problem is a classic RF design flaw that emerges when APs transmit at excessive power levels relative to the attenuation characteristics of the environment. In a brick-walled building, AP signals penetrate walls with significant attenuation. When an AP transmits at maximum power, its signal propagates far beyond the intended cell boundary and reaches client devices that may be physically near other APs but unable to detect the original transmitting AP due to wall attenuation between them. These clients can hear the distant AP ' s signal but cannot hear each other - making them hidden from one another. This leads to simultaneous transmissions, frame collisions at the AP receiver, and dramatic throughput degradation. The
802.11 CSMA/CA mechanism depends on all stations being able to sense the medium before transmitting; hidden nodes defeat this mechanism entirely. The WLSD curriculum consistently identifies excessive AP transmit power in high-attenuation environments as a primary cause of hidden node conditions. The solution is to reduce AP transmit power so that cell sizes remain appropriate for the physical environment. Reference:
WLSD Study Guide - RF Design Fundamentals, Hidden Node Problem, Transmit Power and Cell Size Optimization.

NEW QUESTION # 38
An engineer is upgrading the legacy APs to 802.11ac Wave 2 capable APs. The existing gigabit uplinked switches provide 802.3at. Which switch limitation is a concern?

• A. collision domains
• B. interface throughput
• C. high availability
• D. output power

Answer: D

Explanation:
The primary concern when upgrading to 802.11ac Wave 2 capable APs with existing switches that only provide IEEE 802.3at (PoE+, 30W maximum) is the output power limitation. 802.11ac Wave 2 APs, particularly Cisco ' s 3800 and 4800 series, can require significantly more power than 30W to operate all radios and capabilities at full capacity. The Wave 2 standard introduced features such as Multi-User MIMO (MU-MIMO), beamforming, and additional spatial streams, all of which increase power consumption. When an AP doesn ' t receive sufficient power, it may reduce transmit power, disable radios, or reduce the number of spatial streams - directly degrading wireless performance. Interface throughput (Option A) may also be a concern with multi-gigabit capable APs, but the question specifically asks about the limitation introduced by
802.3at, which is directly a power delivery constraint. Collision domains (Option C) and high availability (Option B) are unrelated to the PoE standard. Reference: WLSD Study Guide - PoE Upgrade Planning,
802.11ac Wave 2 Infrastructure Requirements, Switch Power Budget Considerations.

NEW QUESTION # 39
A customer has two Cisco WLCs configured in a SSO cluster. The wireless network supports a large warehouse. The customer purchases new iPads to replace legacy scanners. Both devices connect to a single SSID named Scanning by using WPA2 Personal. The customer wants to use a standards-based method for fast roaming on the new iPads. Which approach meets the scanner requirement and still supports the legacy scanners?

• A. Enable FT PSK and set Fast Transition to Adaptive for the Scanning SSID.
• B. Enable FT 802.1X and set Fast Transition to Adaptive for the Scanning SSID.
• C. Enable optimized roaming globally and enable FT 802.1X on the Scanning SSID.
• D. Enable optimized roaming globally and enable FT PSK on the Scanning SSID.

Answer: A

Explanation:
The design challenge is enabling IEEE 802.11r Fast BSS Transition for the new iPads (the standards-based fast roaming method) while maintaining backward compatibility for legacy RF scanners that may not support
802.11r. The SSID uses WPA2 Personal (PSK), not 802.1X enterprise authentication - therefore the correct Fast Transition variant is FT PSK (pre-shared key), not FT 802.1X (Options A and B). The critical configuration parameter is setting Fast Transition to Adaptive mode rather than mandatory. Adaptive mode is a Cisco feature that allows the AP and SSID to support both 802.11r-capable clients (which will use FT PSK for fast roaming) and non-802.11r legacy clients (which will use the standard pre-FT roaming process). In Adaptive mode, legacy scanners that cannot negotiate 802.11r during association will fall back transparently to standard roaming, while the new iPads leverage FT PSK for minimal-interruption handoffs. If Fast Transition is set to mandatory, legacy clients that do not support 802.11r will fail to associate entirely. Option C uses optimized roaming globally, which is a different mechanism and does not address the iPads ' specific need for a standards-based fast roaming solution. Reference: WLSD Study Guide - 802.11r Fast BSS Transition, FT PSK Configuration, Adaptive Fast Transition for Mixed Client Environments.

NEW QUESTION # 40
A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and maintain their IP addresses during roaming from the APs attached to WLC-A and WLC-B. Which action accomplishes the requirement?

• A. Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.
• B. Enable AP groups using the same name on both WLCs for each group.
• C. Create an SSO cluster to ensure that client sessions sync between WLCs.
• D. Create a mobility group between the two WLCs to allow auto-anchoring.

Answer: D

Explanation:
The requirement for users to retain their VLAN assignment and IP address when roaming between buildings managed by different WLCs is a Layer 3 roaming scenario. In Cisco ' s wireless architecture, IP address preservation across controller boundaries is achieved through inter-controller mobility - specifically the foreign-anchor mobility tunnel mechanism. When a client roams from Building A (WLC-A) to Building B (WLC-B), WLC-B becomes the foreign controller and WLC-A becomes the anchor controller. WLC-B tunnels the client ' s traffic back to WLC-A, allowing the client to retain its original IP address even while physically associated to an AP managed by WLC-B. This requires creating a mobility group between WLC-A and WLC-B with both controllers configured with the same mobility group name - the group name is the trust identifier that permits the mobility tunnel and anchor-foreign relationship to form. An SSO cluster (Option B) creates redundancy between two WLCs operating as one logical entity, not inter-building roaming between independent controllers. 802.11r (Option C) accelerates re-association but does not preserve IP addresses across different Layer 3 subnets. AP groups (Option D) control SSID and VLAN assignments but do not enable inter-controller IP preservation. Reference: WLSD Study Guide - Inter-Controller Mobility, Layer 3 Roaming, IP Address Preservation.

NEW QUESTION # 41
A wireless engineer must design a WLAN for a university that requires outdoor Wi-Fi access. Which obstruction has the greatest effect on wireless signal propagation?

• A. wind
• B. trees
• C. poles
• D. rain

Answer: B

Explanation:
In outdoor wireless deployments, foliage - particularly dense trees - represents the most significant and variable RF obstruction that engineers must account for during site survey and design. Trees are problematic for multiple compounding reasons: the high water content of living tissue causes signal absorption consistent with the principle that water is an effective absorber of 2.4 GHz and 5 GHz RF energy; the irregular branching structure causes multi-path scattering; and foliage density changes seasonally, meaning signal propagation characteristics measured during winter may differ substantially from summer readings when leaves are fully developed. A fully leafed deciduous tree can attenuate a 5 GHz signal by 6-15 dB depending on density and depth. Wind (Option A) causes only momentary mechanical movement of foliage and is not an obstruction itself. Rain (Option B) causes some absorption at higher frequencies but its effect at 2.4 GHz and
5 GHz in typical conditions is marginal compared to foliage. Poles (Option D) are thin structures with minimal RF impact. Outdoor surveys for university campuses must specifically account for tree locations, canopy density, and seasonal variation. Reference: WLSD Study Guide - Outdoor Wireless Design, Environmental RF Attenuation Factors, Outdoor Site Survey Considerations.

NEW QUESTION # 42
During a client roaming event, which device is responsible for communicating the new Layer 2 EID mapping of a wireless supplicant to the fabric domain?

• A. CP2
• B. WLC
• C. CP1
• D. BN

Answer: B

Explanation:
During a client roaming event in a Cisco SD-Access fabric deployment, the Wireless LAN Controller (WLC) is responsible for communicating the new Layer 2 Endpoint ID (EID) mapping of a wireless supplicant to the fabric domain. In the SD-Access architecture, the WLC acts as a mobility orchestrator and serves as the interface between the wireless domain and the wired fabric. When a client roams from one AP to another, the WLC detects the roaming event and updates the fabric control plane with the new EID-to-RLOC (Routing Locator) mapping by notifying the fabric control plane node (CP). This ensures that the fabric knows the client ' s new location and can route traffic correctly without interruption. The Border Node (BN) handles traffic between the fabric and external networks. CP1 and CP2 are control plane nodes that maintain the mapping database but receive EID update notifications from the WLC - they do not initiate the EID mapping communication themselves. Reference: WLSD Study Guide - SD-Access Wireless Architecture, Client Roaming in Fabric Deployments, EID Mapping and Control Plane Notifications.

NEW QUESTION # 43
A customer has two Cisco Catalyst 9800 Series WLCs named WLC-A and WLC-B in an N+1 configuration with the same WLANs but different Layer 3 interfaces for each WLC, and APs in local mode. WLC-A manages Building A APs and WLC-B manages Building B APs. The customer wants users to remain connected and retain their session state including the IP address when moving between buildings. How must this requirement be incorporated into the design?

• A. Configure WLC-A and WLC-B in a high-availability cluster and set a mobility MAC address.
• B. Connect WLC-A and WLC-B by using the redundancy port to sync client sessions.
• C. Create a mobility tunnel between WLC-A and WLC-B with the same group name.
• D. Implement AP groups for each building by using the same name on WLC-A and WLC-B.

Answer: C

Explanation:
The requirement for users to retain their session state and IP address when roaming between buildings managed by different WLCs is a Layer 3 roaming scenario. In Cisco ' s wireless architecture, IP address preservation across controller boundaries is achieved through inter-controller mobility - specifically the foreign-anchor mobility tunnel mechanism. When a client roams from Building A (WLC-A) to Building B (WLC-B), WLC-B becomes the foreign controller and WLC-A becomes the anchor controller. WLC-B tunnels the client ' s traffic back to WLC-A, allowing the client to retain its original IP address even while physically associated to an AP managed by WLC-B. This requires a mobility tunnel between WLC-A and WLC-B with both controllers configured in the same mobility group name - the group name is the trust identifier that permits the mobility tunnel and anchor-foreign relationship to form. Without the same group name, the controllers will not form a trusted mobility peer relationship. AP groups (Option C) control SSID and VLAN assignments per AP cluster but have no impact on inter-controller roaming. HA cluster configuration (Option B) creates SSO redundancy, not roaming capability between separate N+1 controllers.
Redundancy port connection (Option D) is used for SSO keepalive and state sync, not mobility tunneling.

NEW QUESTION # 44
A consulting engineer for a copper mine is trying to extend the network connectivity of autonomous trucks via Cisco IW3702 APs. The WGB design requirements include: latency-sensitive application (truck slows at
10 sec, stops at 20 sec of connection loss), aggressive scanning and roaming, enterprise-grade security without certificates on each AP, multiple clients in different VLANs on the WGB, and channel scan parameters restricted to only channels in the truck path. Which design approach meets the requirements?

• A. WGB in static mode with EAP Fast connected to a dot1q-capable switch
• B. WGB in mobile station mode with EAP-TLS connected to a dot1q-capable switch
• C. WGB in static mode with EAP-TLS connected to a dot1q-capable switch
• D. WGB in mobile station mode with EAP Fast connected to a dot1q-capable switch

Answer: D

Explanation:
This WGB (Workgroup Bridge) design scenario requires satisfying multiple simultaneous constraints. EAP- FAST (Flexible Authentication via Secure Tunneling) is the correct authentication protocol because it provides enterprise-grade 802.1X security using protected access credentials (PAC) without requiring a certificate to be installed on each AP or WGB device - directly satisfying the enterprise-grade security without certificates requirement. EAP-TLS (Options B and D) requires client certificates on every authenticating device, which is explicitly excluded. Mobile station mode is required rather than static mode (Options C and D) because mobile station mode enables the WGB to aggressively scan and roam to optimal mesh neighbors dynamically, evaluating neighbor signal quality and switching to better RAPs/MAPs as the truck moves along its path. Static mode fixes the WGB to a specific channel or AP, preventing the aggressive scanning and roaming required for the latency-sensitive application. The dot1q-capable switch connection supports multiple clients in different VLANs via 802.1Q VLAN tagging between the WGB and the truck ' s local network switch. Reference: WLSD Study Guide - Workgroup Bridge Design, EAP-FAST Authentication, Mobile vs. Static WGB Mode, Industrial Wireless Design.

NEW QUESTION # 45
An engineer must assess an existing company WLAN to determine the possibility for future IEEE 802.11ac Wave 2 wireless deployment. All access switches are Fast Ethernet-capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points? (Choose two.)

• A. Replace the existing switches with gigabit switches with 10G uplinks.
• B. Replace the existing switches with mGig switches.
• C. Replace the existing wiring infrastructure with the CAT-7E wiring standard.
• D. Ensure that cable distances between access switches and APs are not longer than 55 meters.
• E. Ensure that cable distances between access switches and APs are not longer than 100 meters.

Answer: A,B

Explanation:
Cisco 3800 Series APs support IEEE 802.11ac Wave 2, which can deliver throughput exceeding 1 Gbps. Fast Ethernet switches are limited to 100 Mbps per port, creating a severe bottleneck. The two actions that provide maximum support are replacing with mGig switches (Option A) and replacing with gigabit switches with 10G uplinks (Option B). mGig (Multi-Gigabit Ethernet) switches support 2.5G and 5G speeds over existing CAT
6A cabling, allowing the full throughput of 802.11ac Wave 2 APs to be utilized without replacing the existing cable plant. Gigabit switches with 10G uplinks ensure that the access layer can support 1 Gbps per AP port while providing sufficient uplink capacity. Since the existing cabling is already CAT 6A, which supports 10 Gbps over short distances and 5 Gbps over 100 meters, there is no need to replace the wiring (Option D eliminates). The 100-meter distance limitation (Option C) already applies to standard Ethernet and is met by CAT 6A - this is not an action but a constraint check. Option E (55 meters) is only relevant for specific
5GBASE-T configurations and doesn ' t maximize support compared to A and B. Reference: WLSD Study Guide - mGig Infrastructure, 802.11ac Wave 2 Infrastructure Design, Switch Upgrade Planning.

NEW QUESTION # 46
An engineer must configure the virtual IP address on multiple controllers in a mobility group. Which rule must the engineer follow to ensure proper roaming?

• A. Use the same IP address for each WLC.
• B. Use a unique IP address for each WLC.
• C. Ensure that the DNS Host Name field is defined.
• D. Ensure that the DNS entry is tied to the virtual IP address of the WLC.

Answer: A

Explanation:
In a Cisco wireless mobility group, all Wireless LAN Controllers (WLCs) must be configured with the same virtual IP address to ensure proper roaming. The virtual IP address is a Layer 3 construct used by wireless clients during the DHCP renewal process when roaming between subnets managed by different WLCs. All WLCs in the same mobility group use the same virtual IP (typically from the unused 1.1.1.0/24 or similar non- routable space) so that clients receive consistent DHCP server responses regardless of which controller they are associated with. If different virtual IP addresses were used (Option B), clients roaming between controllers would experience DHCP failures during inter-controller roaming because the DHCP server address seen by the client would change. Options A and C relate to DNS hostname configuration, which is useful for AP discovery but does not affect the roaming behavior of client devices. The virtual IP address consistency across all mobility group members is a fundamental requirement for seamless inter-controller roaming. Reference: WLSD Study Guide - Mobility Group Configuration, Virtual IP Address, Inter- Controller Roaming Requirements.

NEW QUESTION # 47
A community bank has three campus locations and one HQ with the data center. Each campus has four Cisco Catalyst 9120 APs. Poor WAN uplinks cause impacted connectivity back to HQ, and each campus is planned to have its own EWC controller based on C9120 AP to keep traffic local. Guest WLAN will be routed locally.
Employee WLAN must be authenticated 802.1x PEAP via HQ ISE but can pass traffic locally once authenticated. HQ WLC will be the primary backup WLC for each WLC. Which design approach should the consulting engineer take?

• A. Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server added to EWC.
• B. One C9120 campus AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC paired as mobility peer and configured as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN. The campus employee WLAN will need the guest anchor back to the HQ employee WLAN.
• C. One C9120 AP in each campus must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server to be added to EWC.
• D. Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby with HQ WLC as N+1 backup. The campus guest WLAN will use the guest anchor to HQ WLC for guest VLAN access, and employee WLAN will need the HQ AAA server added to EWC.

Answer: C

Explanation:
This community bank design scenario requires precise alignment of EWC deployment scale, AAA integration, and traffic routing decisions with the stated constraints. With four APs per campus and a goal of local traffic handling, converting a single C9120 to EWC mode is optimal - converting two APs to EWC (Options B and C) on a four-AP campus wastes 50% of campus AP infrastructure for controller functions rather than client service. The single EWC AP serves as the active local controller for the remaining three client-serving APs. The HQ WLC set as N+1 backup ensures that if the branch EWC fails, the remaining APs fall back to the centralized controller. For the guest WLAN, local web authentication on the guest VLAN provides the locally routed guest access requirement without requiring WAN connectivity to HQ. For the employee WLAN, adding the HQ ISE AAA server to the EWC ' s RADIUS configuration enables 802.1x PEAP authentication to traverse the WAN to ISE at the time of client association. Once authenticated, traffic is locally switched - satisfying both the central authentication and local traffic routing requirements simultaneously. Option D ' s use of guest anchor for the employee WLAN is architecturally incorrect and would route traffic through HQ rather than locally. Reference: WLSD Study Guide - EWC Design, N+1 Redundancy, AAA Integration for Branch WLANs, Local Web Authentication.

NEW QUESTION # 48
A customer has two Cisco 5520 WLCs that manage all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to their primary configured controller when it recovers.
Which configuration task fixes the issue?

• A. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A access points.
• B. Enable AP fallback globally on the WLC.
• C. Use DHCP Option 43 and specify WLC in location A as primary.
• D. Change the AP Failover Priority to critical.

Answer: B

Explanation:
Enabling AP fallback globally on the WLC allows access points to reconnect to their primary controller after they have connected to a secondary controller due to the primary being offline. This is the exact behavior described in the scenario - APs successfully fail over to the secondary WLC but do not return to the primary WLC when it recovers. AP Fallback is a WLC-level setting that monitors the availability of each AP ' s configured primary controller and initiates a reconnection when the primary becomes reachable again.
Without AP Fallback enabled, APs remain on whatever controller they most recently joined - in this case, the secondary - even after the primary recovers. The CAPWAP AP Controller IP Address command (Option A) permanently changes the primary controller configuration on the AP, which is not the intended solution - the AP already has the correct primary configured. DHCP Option 43 (Option B) is used for initial AP discovery, not fallback. AP Failover Priority (Option D) controls which APs are processed first during a failover event, not whether APs return to their primary controller. Reference: WLSD Study Guide - AP Fallback Configuration, N+1 Redundancy Recovery, Controller Primary/Secondary Hierarchy.

NEW QUESTION # 49
An engineer in a branch office that does not have a wired backhaul must ensure that local clients can be switched locally and authenticated centrally. In which mode must the AP be configured?

• A. Flex+Bridge
• B. Cisco FlexConnect
• C. RAP
• D. MAP

Answer: A

Explanation:
Flex+Bridge mode is a specialized AP operating mode that combines two distinct Cisco wireless capabilities:
FlexConnect (for local switching of client data traffic and central authentication via the WLC) and Bridge
/Mesh mode (enabling wireless backhaul when no wired Ethernet uplink is available). In a branch environment without wired backhaul, a standard FlexConnect AP (Option D) cannot operate because FlexConnect still requires an Ethernet connection for its control plane. Bridge mode alone provides mesh backhaul but does not support the local switching with central authentication model required here. MAP (Option A) is a Mesh Access Point role for wireless backhaul, and RAP (Option C) is a Root Access Point with a wired connection - neither meets the no-wired-backhaul requirement with local switching.
Flex+Bridge uniquely satisfies both requirements: the Flex component allows locally switched VLANs to be bridged directly to the access layer without traversing the WAN, while the Bridge component enables the AP to use a wireless mesh link for its backhaul uplink. Central authentication is maintained via the CAPWAP control tunnel over the mesh link. Reference: WLSD Study Guide - FlexConnect Design, Mesh Networking, Flex+Bridge Mode Configuration and Use Cases.

NEW QUESTION # 50
A network engineer is deploying Cisco 9130I APs on multiple Cisco Catalyst 9800-80 WLCs with Cisco Catalyst Center. The engineer must enable Cisco AI Analytics and location analytics to use the RRM features to automatically manage the WLC RF profiles. Which type of license must be used on Cisco Catalyst Center?

• A. Catalyst Advantage
• B. Catalyst Essentials
• C. Right-To-Use
• D. SNTC SmartNet

Answer: A

Explanation:
Cisco Catalyst Center ' s AI-driven network management capabilities - including AI Analytics, AI-Enhanced RRM (Radio Resource Management), location analytics (DNA Spaces integration), and automated RF profile management - are exclusively available under the Catalyst Advantage license tier. The Advantage tier builds upon the Essentials tier and adds access to the full suite of AI/ML-powered assurance and optimization features. Specifically, AI-Enhanced RRM leverages machine learning models trained on historical RF telemetry to predict and prevent RF issues, dynamically adjust channel and power assignments, and automate RF profile selection - capabilities that cannot be activated without the Advantage license. Location analytics through Catalyst Center integrates with Cisco Spaces to provide real-time client location tracking, asset tracking, and spatial analytics. Catalyst Essentials (Option C) provides basic device management, software image management, and network plug-and-play provisioning - it does not include AI Analytics or advanced RRM automation. Right-To-Use (Option B) is a legacy licensing model not applicable to Catalyst Center.
SNTC SmartNet (Option D) is a support and maintenance contract, not a software feature license. Reference:
WLSD Study Guide - Cisco Catalyst Center Licensing, AI-Enhanced RRM, Catalyst Advantage Feature Set.

NEW QUESTION # 51
An enterprise network administrator is asked to set up an experimental WLAN for a collaboration project with a local service provider. The WLAN must be anchored to a WLC in the service provider data center using legacy mobility mode. After the configurations are completed on the WLCs and the firewalls in the path, the data path mobility tunnel is failing to come up. What should be performed by the administrator to debug the issue?

• A. Use the mapping command on the WLC.
• B. Establish a Telnet connection from a local PC to the firewall on port 16666.
• C. Use the mping command on the WLC.
• D. Establish a Telnet connection from a local PC to the firewall on port 97.

Answer: B

Explanation:
When a data path mobility tunnel fails to come up between WLCs, one of the key troubleshooting steps is to verify whether the necessary ports are open through firewalls in the path. Cisco AireOS mobility tunnels use UDP port 16666 for mobility control traffic and IP Protocol 97 (EtherIP) for mobility data traffic in legacy mode. Establishing a Telnet connection from a local PC to the firewall on port 16666 tests whether the control path port is reachable and not being blocked by the firewall. If the Telnet connection fails, it confirms that the firewall is blocking port 16666, which would prevent the mobility control tunnel from establishing - a prerequisite for the data tunnel. While a Telnet test to port 16666 specifically tests the control path, in practice this is the first verification performed when the data path cannot establish (since the data path depends on the control path being operational). IP Protocol 97 cannot be tested via Telnet (which is TCP). The mping command (Option D, not ' mapping ' ) tests mobility tunnel connectivity from the WLC itself after the tunnel is established. Reference: WLSD Study Guide - Mobility Tunnel Troubleshooting, Firewall Port Requirements, UDP 16666 and IP Protocol 97.

NEW QUESTION # 52
A customer designs a Cisco wireless environment to provide connectivity to employees and guests. The guest SSID must be configured on three anchor WLCs named Anchor1, Anchor2, and Anchor3 in a DMZ. The guest anchor priority must be configured to ensure that Anchor1 has the highest priority. Which priority level must be incorporated in the design for Anchor1?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: A

Explanation:
In Cisco ' s guest anchor WLC deployment model, multiple anchor controllers can be configured in a DMZ to provide redundancy for guest WLAN traffic. The anchor priority value determines which anchor controller is preferred for establishing the guest mobility tunnel from the foreign WLC. Cisco ' s anchor priority system assigns the highest preference to the lowest numerical priority value. Priority 1 is the highest priority, meaning the foreign WLC will prefer Anchor1 when establishing the CAPWAP mobility tunnel for anchoring guest client traffic. Priority 2 would be assigned to Anchor2, and Priority 3 to Anchor3, creating a deterministic failover hierarchy. If Anchor1 becomes unreachable, the foreign controller automatically falls over to Anchor2, then to Anchor3. Priority 0 is not a valid anchor priority value in the Cisco WLC configuration. This design pattern is critical for enterprise guest deployments where DMZ anchor redundancy must be maintained without manual intervention. Reference: WLSD Study Guide - Guest Wireless Architecture, Anchor WLC Configuration, Mobility and DMZ Design.

NEW QUESTION # 53
An enterprise is using wireless as the main network connectivity for clients. To ensure wireless network availability, two standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but fails. Which protocol needs to be allowed between the networks that the controllers are installed?

• A. IP Protocol 77
• B. IP Protocol 97
• C. IP Protocol 87
• D. IP Protocol 67

Answer: B

Explanation:
When eping (EoIP ping) fails between two Cisco Wireless LAN Controllers, it indicates that the data path of the mobility tunnel is blocked. In Cisco AireOS wireless networks, the mobility data path uses IP Protocol 97 (EtherIP - Ethernet-over-IP encapsulation) for tunneling client traffic between the anchor and foreign controllers. This is distinct from the control path, which uses UDP port 16666. When the mobility data path (IP Protocol 97) is blocked by a firewall or ACL between the two controllers ' networks, eping will fail because eping specifically tests the EoIP data encapsulation path. After a power cut, when clients disconnect and attempt to roam between APs on different controllers, the mobility tunnel must be operational for session continuity. If IP Protocol 97 is blocked, the mobility data plane cannot function, causing client disconnections during inter-controller roaming events. The other IP protocols listed (67, 77, 87) are not used for Cisco WLC mobility tunneling.

NEW QUESTION # 54
An engineer is deploying new APs to serve IEEE 802.11g through 802.11ac clients and wants to use the Ekahau Site Survey tool to verify RF coverage. Management wants the engineer to verify and create coverage maps as quickly as possible. Which configuration accomplishes the goal?

• A. passive mode with one wireless adapter
• B. passive mode with two wireless adapters
• C. active mode with two wireless adapters
• D. active mode with one wireless adapter

Answer: B

Explanation:
In Ekahau Site Survey, passive mode involves listening to beacon frames and probe responses from deployed APs without the survey laptop actively associating to any SSID. This is significantly faster than active mode because no association, DHCP, or throughput test overhead is introduced - the surveyor simply walks the floor while Ekahau passively captures signal strength data from all visible APs simultaneously. Using two wireless adapters in passive mode provides a critical speed advantage: one adapter scans 2.4 GHz channels while the second adapter simultaneously scans 5 GHz channels. Without dual adapters, a single adapter must time-multiplex between bands, reducing the sample rate per band and either slowing the survey walk or producing sparser data. Active mode (Options B and C) is used when throughput measurements are required for specific application validation such as voice or video, but it is inherently slower due to association overhead and sequential testing. The combination of passive scanning and dual adapter configuration delivers the highest possible data collection rate per unit of walk time.
