A hospital needs seamless roaming between APs for wireless medical devices. Which WLAN feature is most critical?

• A.Mobility groups
• B.CleanAir
• C.DFS channels
• D.Band Select

A network engineer must design a new Cisco wireless solution that contains three Cisco 9800-40 WLCs. WLC1 and WLC2 will be combined into one logical unit with SSO and a backup WLC named WLC3 will be joined by using a mobility tunnel. Link redundancy between the WLCs and the switches is required. Which WLCs must the design provide connectivity to the network equipment for LAG to be effective in an SSO failover scenario?

• A.WLC1
• B.WLC1, WLC2, and WLC3
• C.WLC1 and WLC2
• D.WLC2

Explanation:
Link Aggregation
Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard. It bundles all of the controller's distribution system ports into a single 802.3ad port channel. This reduces the number of IP addresses required to configure the ports on your controller. When LAG is enabled, the system dynamically manages port redundancy and load balances access points transparently to the user.
LAG simplifies controller configuration because you no longer require to configure primary and secondary ports for each interface. If any of the controller ports fail, traffic is automatically migrated to one of the other ports. As long as at least one controller port is functioning, the system continues to operate, access points remain connected to the network, and wireless clients continue to send and receive data.

A network engineer is managing a wireless network for a large corporate campus with the configuration:
- Two Cisco Catalyst 9800 Series Wireless Controllers: WLC1 and WLC2, both running Cisco IOS XE Software version 17.9.5. These controllers are configured in the same mobility group, named CorpMobility, to enable seamless roaming for clients across the campus.
- The WLAN Guest is deployed on both controllers to provide internet access for visitors. Due to the company's strict security policies, all guest traffic must be anchored to WLC2 for centralized internet access and firewall enforcement.
- Client data traffic from the Guest WLAN on WLC1 be tunneled to WLC2, ensuring consistent policy application regardless of where the client connects.
- The mobility tunnel between WLC1 and WLC2 is established over the campus backbone network, which occasionally experiences latency spikes due to high traffic loads.
Which set of actions should the engineer take to validate the mobility tunneling for the control and data paths?

• A.On WLC2, run show wireless mobility summary to verify that WLC1 is listed as a mobility peer with control and data links Up. Then, connect a client to the Guest WLAN on WLC2 and run show wireless client mac-address detail on WLC2 to confirm that the client's mobility state is Anchored with WLC1 as the anchor controller.
• B.On WLC1 and WLC2, run show wireless mobility summary to check that the mobility peer status, and then use ping to test connectivity between their management IPs. Then restart the two Cisco Catalyst 9800 Series Wireless Controllers and check that the mobility tunnel between WLC1 and WLC2 is established over the campus backbone network.
• C.On WLC1, run show wireless mobility summary to verify that WLC2 is listed as a mobility peer with control and data links Up. Then, connect a client to the Guest WLAN on WLC1 and run show wireless client mac-address detail on WLC1 to confirm that the client's mobility state is Anchored with WLC2 as the anchor controller.
• D.On WLC2, run show wireless mobility anchor to verify the anchoring configuration, and on WLC1, run show wireless client summary to check client associations. Then restart the two Cisco Catalyst
  9800 Series Wireless Controllers and check that the mobility tunnel between WLC1 and WLC2 is established over the campus backbone network.

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