Question # 10

WLC SSO is set up between two WLCs in a service provider network serving public spaces. On WLC failover, it is noticed that only about half of the original client count is now showing on the secondary WLC, although it is currently showing the role as active. Which design side case explains the issue?

A.

The secondary WLC platform does not support the required client count.

B.

The WLCs had not completed database sync before the primary failure.

C.

SSO is not configured correctly.

D.

Some client sessions were in WebAuth-Req state before failover.

Question # 12

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.

Question # 13

An engineer must repurpose a lab WLC appliance for use in the production environment of the enterprise. After the new WLC is configured with the information of the other WLC, the mobility tunnels are still not coming up. What is the reason?

A.

A firewall is blocking UDP port 16667 between the WLCs.

B.

The WLC management interfaces are in the same VLAN.

C.

The hardware platform is incompatible.

D.

The mobility groups are different.

Question # 15

How should the concept of mobility domains and mobility groups be explained to a customer?

A.

WLCs do not need to be in the same mobility domain to communicate with each other Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

B.

A mobility group does not constrain the distribution of security context of a client and also does not constrain AP fail-over between controllers when the WLCs are in the same mobility domain.

C.

if WLCs are in same mobility domain, they communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

D.

If WLCs are in the same mobility domain, they communicate with each other but. if an anchor WLC ® present, it must: be in the same mobility domain for communication to be possible.

Question # 16

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 dynamics interfaces.

D.

Interface connection to two separate nonstacked switches is available.

Question # 17

Guest anchoring is configured for a newly created SSID for your company. It has been noticed that the mobility tunnels are not up, and that MPING fails from your foreign WLC to the anchor WLC. What is the reason that it is failing?

A.

A rule is needed at the firewall to allow UDP port 16666 for communication to

work.

B.

A rule is needed at the firewall to allow UDP port 97 for communication to work.

C.

A rule is needed at the firewall to allow TCP port 97 for communication to work.
