  Correct Answer: DE

• Question 3:

  An engineer created a design where the HQ has a Cisco 5520 Wireless LAN Controller with 2000 APs associated to it. If a controller at one of the remote sites fails, the APs at that site fall back to a central controller. Global AP Failover Priority must be enabled. Which design approach must be taken to prevent the critical APs at HQ from going down and still allow APs to failover to the HQ controller?

  A. Set all the APs at HQ to a failover priority of "high" and set the remote site APs to "normal".

  B. Set all the APs at HQ to a failover priority of "medium" and set the remote site APs to "high".

  C. Ensure that the critical APs at HQ have a failover priority of "critical", leave the rest of the HQ APs at "medium", and set the remote site APs to "high".

  D. Create an access list on the HQ router that blocks CAPWAP discovery on UDP port 5246 so that the remote APs cannot kick off the APs at HQ.

  Correct Answer: C

• Question 4:

  A network engineer is working for an enterprise where most of the laptops support 802.11v. To optimize the client roaming experience, configuration changes must be made on the corporate SSID to force clients to use the best APs based on the 802.11 v BSS transition message. Which configuration meets this requirement?

  A. Enable BSS transition for the SSID and disable dissociation imminent to avoid client disconnects.

  B. Enable the BSS transition option with an optimized roaming timer for the corporate SSID.

  C. Enable coverage hole detection and BSS transition and disable dissociation imminent.

  D. Disable coverage hole detection and enable 802.11k for the corporate SSID.

  Correct Answer: A

• Question 5:

  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. DHCP Option 43 information is incorrect.

  B. APs do not have their secondary WLC information configured correctly.

  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 primary WLC information configured correctly.

  Correct Answer: BE

• Question 6:

  A customer has this wireless design:

  1.

  two Cisco Catalyst 9800 Series wireless controllers configured in a high-availability SSO cluster to manage APs in the local office network

  2.

  100 APs in local mode and registered to the high-availability cluster

  3.

  one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ

  4.

  Cisco ISE for user authentication and authorization

  The customer wants to deploy a new SSID to support staff BYOD devices and authenticate users via Cisco ISE. The SSID terminates on the anchor WLC. How must the requirement be incorporated into the design to address the AAA servers for the WLAN?

  A. Send the AAA server accounting and authentication traffic from the high-availability cluster.

  B. Send the AAA server accounting and authentication traffic from the anchor WLC.

  C. Send the accounting traffic from the anchor WLC and the authentication traffic from the high-availability cluster.

  D. Send the accounting traffic from the high-availability cluster and the authentication traffic from the anchor WLC.

  Correct Answer: B

• Question 7:

  An engineer is planning a wireless deployment with two members in a mobility group. The engineer notices that there are issues establishing the mobility tunnel. The engineer must test the mobility EoIP data packet communication between two controllers. Which command runs this test?

  A. debug route

  B. eping

  C. debug icmp

  D. mping

  Correct Answer: D

• Question 8:

  Users who leave the office with a wireless headset must be able to hand off the voice call with minimal disruption. The engineer drafted four possible floor plans for AP placement:

  1.

  red dots and arrows represent the direction of travel

  2.

  blue dots represent the AP placements

  Which floor plan provides the requested functionality?

  

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

• Question 9:

  A customer has a Cisco wireless network that has these configurations and components:

  two Cisco Catalyst 9800 Series WLCs in a high availability cluster

  2.

  50 Cisco 2800I APs

  3.

  all SSIDs and services are 5 GHz only

  A security mandate requires that rogue APs be scanned and identified in 2.4 GHz and 5 GHz bands and must not impact existing client connectivity. How must the wireless network be reconfigured to meet the requirement without purchasing additional APs?

  A. Set the XOR radio role to Client Serving and the slot 1 radio to Sniffer mode on all the APs.

  B. Set the XOR radio role to Monitor mode and the slot 1 radio to Client Serving on all the APs.

  C. Set the XOR radio role to Client Serving and the slot 1 radio to Monitor mode on all the APs.

  D. Set the XOR radio role to Sniffer mode and the slot 1 radio to Client Serving on all the APs.

  Correct Answer: B

• Question 10:

  A customer currently is migrating the old wireless infrastructure to a new Cisco IOS XE-based solution and wants a mobility group configured between a Cisco AireOS WLC and an IOS XE WLC. During the migration phase from AireOS to IOS XE, the Layer 3 roaming between the WLCs must be seamless. Which action meets the requirements?

  A. For the same SSIDs, use the same VLAN IDs and subnets on both WLCs.

  B. For different SSIDs, use different VLAN IDs and subnets on both WLCs.

  C. For different SSIDs, use the same VLAN IDs and subnets on both WLCs.

  D. For the same SSIDs, use different VLAN IDs and subnets on both WLCs.
