Cisco CCNP Enterprise 300-425 Questions & Answers

• Question 201:

  A customer is running a guest WLAN with a foreign/export-anchor setup. There is one anchor WLC in the US and two in Europe. Anchor WLC priorities are used to prefer local anchors. During a routine network audit, it is discovered that a large number of guest client sessions in the US are anchored to the WLCs in Europe. Which reason explains this behavior?

  A. The foreign WLC failed and recovered.

  B. The US anchor WLC failed and recovered.

  C. The US anchor WLC is anchored to itself with a priority value of zero.

  D. The anchor WLC is in the same mobility group.

  Correct Answer: B

• Question 203:

  An engineer must create data link redundancy for the company's Cisco Wireless LAN controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three features of LAG-based redundancy influenced this decision? (Choose three.)

  A. Packets are always sent out on the same port they are received on.

  B. All interface traffic passes as long as one port is up.

  C. The same port has multiple untagged dynamic interfaces.

  D. Interface connection to two separate nonstacked switches is available.

  E. Full bandwidth of all links is available.

  F. Ports are grouped into multiple LAGs.

  Correct Answer: ABF

• Question 204:

  Clustering Cisco WLCs into a single RF group enables the RRM algorithms to scale beyond the capabilities of a single Cisco WLC. How many WLC and APs in an RF group can the controller software scale up to in WLC release 8.9 depending on the platform?

  A. up to 20 WLCs and 1000 APs

  B. up to 20 WLCs and 3000 APs

  C. up to 20 WLCs and 4000 APs

  D. up to 20 WLCs and 6000 APs

• Question 208:

  An engineer has configured guest anchoring for a newly created SSD however, the mobility tunnels are not up, and EPING is failing from the foreign WLC to the anchor WLC. Which traffic flow must be allowed at the firewall to enable the communication?

  A. UDP port 16666

  B. IP protocol 97

  C. UDP port 97

  D. TCP port 97

  Correct Answer: B

• Question 209:

  Which statement about creating a mobility group is true, excluding mobility anchors?

  A. Each WLC must use the same mobility name and be defined as a peer in each other's static mobility members list.

  B. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair considered separately as a mobility peer.

  C. The WLCs do not have to be of the same model or type to be a member of a mobility group, however each member should be running different software versions.

  D. A mobility groups does not require all WLCs in the group to use the same virtual IP address.

  Correct Answer: B

• Question 210:

  Refer to the exhibit.

  

  A client roams between two APs that are registered to two different controllers, where each controller has an interface in the client subnet. Both controllers are running AireOS. Which scenario explains the client roaming behavior?

  A. Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is moved from the original controller to the new controller.

  B. Controllers do not exchange mobility control messages (over UDP port 16666) and the client database, entry is not moved from the original controller to the new controller.

  C. Controllers exchange mobility control messages (over UDP port 16666) and a new client session is started with the new controller.

  D. Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is tunneled from the original controller to the new controller.

  Correct Answer: A
