What happens to an AP when a flex profile name is changed in a site tag?

A. It automatically updates its firmware without causing any downtime.

B. It temporarily disables all the currently broadcasting SSIDs.

C. It switches to a backup controller without any interruption.

D. It is forced to rejoin the controller by disconnecting the DTLS session.

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. 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.

B. 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.

C. 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.

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 N+1 backup. The branch guest WLAN will use local web auth on guest VLAN.

A customer purchases this Cisco equipment for a new branch office: • 20 Cisco Catalyst 9120 APs • five Catalyst 9130 APs • a single Catalyst 9300 Series Switch The customer wants to extend its existing wired and wireless fabric-enabled network to the branch office and manage all devices via a centrally deployed Cisco Catalyst Center (formerly DNA Center). Which Cisco Catalyst Center licenses are required for the branch office equipment?

A. Cisco Catalyst Advantage for the switch and all the APs

B. Cisco Catalyst Essentials on the APs and Cisco Catalyst Advantage on the switch

C. Cisco Catalyst Essentials on the switch and all the APs

D. Cisco Catalyst Advantage on the APs and Cisco Catalyst Center Premiere on the switch

An educational organization recently deployed an anchored WLAN and has a high number of client connections at any given time that stream video. The wireless infrastructure includes two Cisco 9800 WLCs. To prevent web traffic being slow, an engineer must configure the deployment to prevent excessive fragmentation of the client data. Which configuration must the engineer apply?

A. Set the MTU on both controllers to match.

B. Increase the MTU on both controllers.

C. Adjust the TCP MSS value below the fragmentation point.

D. Set the do not fragment bit on the mobility tunnel.

A customer has a Cisco wireless network that supports VoWLAN services. The customer wants supported voice clients to receive roaming recommendations and suggestions from APs. This functionality must not impact non-VoWLAN clients. What should be enabled on the VoWLAN SSID?

A. 802.11k neighbor lists

B. CCKM with 802.1X

C. 802.11v BSS Transition Management

D. 802.11r Fast Transition

A network engineer is configuring high availability on an access point. What is the maximum number of controllers that can be configured?

A. 1

B. 2

C. 3

D. 4

An engineer is performing a passive survey report. The coverage heat map shows the entire site with all signal levels. To see only the desired coverage, which action must the engineer take?

A. Change the color scheme to show the desired heat map.

B. Use the RSSI calibration tool to configure the receiver sensitivity.

C. Use the RSSI slider to set the heat map to the desired cutoff filter.

D. Filter the results to show the desired APs only.

A wireless engineer must design a backhaul link. The engineer has a mesh access point that has a wired connection back to the infrastructure. What must be changed in the AP role before a change is made in the AP mode?

A. monitor

B. RAP

C. bridge

D. local

A customer wants a network engineer to design a Cisco wireless solution that will have redundancy through SSO and LAG. APs in the executive office must reassociate to the WLC as soon as possible in the event of a failure. The WLCs are located in a remote data center. The head office uses a WAN for connectivity with the data center. Which priority must be incorporated in the design to be assigned to the executive APs?

A. high

B. medium

C. low

D. critical

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 802.1X and set Fast Transition to Adaptive for the Scanning SSID.

B. Enable optimized roaming globally and enable FT 802.1X on the Scanning SSID.

C. Enable optimized roaming globally and enable FT PSK on the Scanning SSID.

D. Enable FT PSK and set Fast Transition to Adaptive for the Scanning SSID.
