Cisco CCNP Enterprise 300-425 Questions & Answers

• Question 51:

  A wireless network consists of:

  1.

  two IOS XE controllers installed in a data center

  2.

  9100 series APs

  3.

  corporate and a guest WLAN

  The customer must high availability pair two Cisco WLCs for the client SSO.

  Which two design approaches must the engineer take to meet the requirement? (Choose two.)

  A. The controllers must have the same number of licenses.

  B. Both WLCs must have the same redundancy management IP address.

  C. Both WLCs must have the same service port IP address.

  D. Each WLC must have a unique redundancy management IP address.

  E. The controllers must run the same operating system version.

  Correct Answer: BE

• Question 52:

  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

  Correct Answer: C

  Reference:

  

  So max 2 will be supported on an AP.

• Question 53:

  A customer has this wireless design: two Cisco Catalyst 9800 Series wireless controllers that are configured in a high-availability SSO cluster to manage the APs in a local office network 100 APs in local mode that are registered to the high-availability cluster one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ a CAPWAP tunnel in UP state between the high-availability cluster and the anchor WLC

  The customer wants the anchored traffic to remain up if a single WLC in the high-availability cluster fails. How must this requirement be incorporated into the design?

  A. Configure the APs with the high-availability cluster as the primary base.

  B. Deploy EMC APs as anchors and configure a high-availability cluster.

  C. Create a separate EoIP tunnel for each WLC in the high-availability cluster.

  D. Configure the mobility MAC address for the high-availability cluster.

  Correct Answer: D

• Question 54:

  Refer to the exhibit.

  

  A network engineer has identified that during a recent controller failure, several APs failed over to the tertiary controller instead of the secondary controller. The configuration from one of the APs is provided. Which design consideration led to the issue?

  A. The secondary controller was at capacity.

  B. The secondary controller is an SSO configuration.

  C. The tertiary controller is an HA-SKU controller, so it took priority.

  D. The tertiary controller is in the same subnet as the primary controller.

  Correct Answer: C

• Question 55:

  A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?

  A. RF Profile

  B. AP Groups

  C. VLAN Select

  D. AAA Override

  Correct Answer: C

• Question 56:

  An engineer must create a multicampus architecture wireless design to accommodate 4500 access points for wireless data and guest access. Which model controller fits the requirements to support all access points on one high availability controller setup?

  A. 3504

  B. 5508

  C. 5520

  D. 8540

  Correct Answer: D

• Question 57:

  An engineer must optimize client roaming after noticing that clients in the environment are not roaming as expected. Upon reviewing an over-the-air packet capture, the engineer sees that the AP is sending a BSS Transition Management query to the client, which causes it to roam. The disassociation imminent feature is not enabled on the WLAN. What is the cause of the issue?

  A. Low RSSI check is enabled.

  B. Fast Transition is disabled.

  C. Band Select is enabled.

  D. Optimized roaming is enabled.

  Correct Answer: B

• Question 58:

  A customer Wi-Fi deployment is experiencing the sticky client problem and must enable the optimized roaming feature. The wireless clients have valid security credentials for an SSID and can see an AP that offers that SSID to join. What must be configured to enhance roaming?

  A. RSSI threshold

  B. disable DFS

  C. disable 802.11k

  D. enable data rates

  Correct Answer: A

• Question 59:

  An engineer is working for an enterprise and deployed a Cisco 9800 Series Wireless Controller. The wireless infrastructure serves the employees and guest users across the company. The engineer must configure the controller to alleviate the sticky client issue in the deployment. Which action resolves the issue?

  A. Enable CHDM.

  B. Enable Optimize Roaming.

  C. Enable 802.11k.

  D. Enable data RSSI to -90db.

  Correct Answer: B

• Question 60:

  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 that are attached to WLC-A and WLC-B. Which action accomplishes the requirement?

  A. Create a mobility group between the two WLCs to allow auto-anchoring.

  B. Create an SSO cluster to ensure that client sessions sync between WLCs.

  C. Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.

  D. Enable AP groups using the same name on both WLCs for each group.

  Correct Answer: A
