A campus has two controllers, each with client VLANs on different subnets. A client associated to an AP on WLC-1 roams to an AP on WLC-2. Which behavior does the mobility design produce, and what is required?

• A. A Layer 3 roam occurs; the client keeps its IP address through an asymmetric tunnel from the anchor to the foreign controller.
• B. A Layer 2 roam occurs; no mobility configuration is required.
• C. A Layer 3 roam occurs; the client must obtain a new IP address from WLC-2.
• D. The client is deauthenticated and must reauthenticate from the beginning.

A customer has multiple WLCs running in N+1 redundancy with APs load balanced between the WLCs. The customer performs AP failover testing between the WLCs and notices that some of the APs do not move back to their primary WLC after it recovers. What are two points that must be addressed in the design? (Choose two.)

• A. APs do not have their primary WLC information configured correctly.
• B. DHCP Option 43 information is incorrect.
• C. APs failover priorities are set to Low.
• D. AP Fallback is not enabled on one of the WLCs.
• E. APs do not have their secondary WLC information configured correctly.

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. Implement AP groups for each building by using the same name on WLC-A and WLC-B.
• 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. Configure WLC-A and WLC-B in a high-availability cluster and set a mobility MAC address.

An engineer is designing a wireless network in a historic building that has large rooms and ornate wall coverings. Which approach must be considered first when placing access points?

• A. RF interference
• B. RF coverage
• C. cell overlap
• D. aesthetics

A retail customer opened two new branch locations, and the main store HQ handles data center operations. Each branch location has three Cisco Catalyst 9130 APs. The data center has a Catalyst 9800 WLC with 18 Catalyst 9130 APs. Growing business and poor WAN uplinks cause impacted branch AP and wireless client connectivity back to HQ, and each branch location is now planned to have its own EWC controller based on C9130 AP to keep traffic local. This new design must accommodate: guests and employees sharing the same WLAN with different VLANs, guest uplink and downlink traffic restricted to 2 Mbps, and each branch acting as secondary or tertiary backup to another branch with the data center WLC always being the primary. Which design approach should the consulting engineer take?

• A. One C9130 branch AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as N+1 backup. The branch guest WLAN will use local web auth on guest VLAN.
• B. Two C9130 branch APs must be converted to EWC mode, one for the active controller and the other for standby, with the standby EWC set as N+1 backup. HQ AAA must be added to EWC, and WLAN with dot1x + AAA override must be configured.
• C. Two C9130 branch APs must be converted to EWC mode, one for the active controller and the other for standby, with HQ WLC set as a primary N+1 backup, and other branches' EWC must be added as mobility peers. The branch WLAN will use the guest anchor to HQ WLC for guest VLAN access.
• D. One C9130 branch AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as a primary N+1 backup and other branches' EWC AP as secondary and tertiary. HQ AAA must be added to EWC, and WLAN with MAB + AAA override must be configured.
