Question 91
How should the concept of mobility domains and mobility groups be explained to a customer?
A. 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 WLC is in the same mobility domain.
B. If WLCs are in the same mobility domain, they communicate with each other but, if an anchor WLC is present, it must be in the same mobility domain for communication to be possible.
C. If WLCs are in the 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. 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.
Question 92
An engineer must ensure that the new wireless LAN deployment can support seamless roaming between access points using a standard based on an amendment to the 802.
11 protocol. Which protocol must the engineer select?
A. 802.11i
B. 802.11ac
C. 802.11r
D. 802.11e
Question 93
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.
Question 94
An engineer has configured guest anchoring for a newly created SSID 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

Question 96
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.
Question 97
An engineer has successfully configured high availability and SSO using two Cisco 5508 Wireless LAN Controllers. The engineer can access the Active PrimaryWLC, but the Secondary Standby WLC is not accessible. Which two methods allow access to the standby unit? (Choose two.)
A. via the console connection
B. SSH to the redundancy management interface of the primary WLC
C. SSH to the service port interface
D. SSH to the virtual interface of the secondary WLC
E. SSH to the management interface of the primary WLC
Question 98
A customer has two Cisco 5508 WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary CiscoWLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants to convert the N+1 model to an HA model and provide SSO. Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued on the secondary Cisco WLC and it fails. Which parameter needs to be in place to complete the configuration?
A. A cable in the RP port
B. The secondary Cisco WLC needs a minimum of 50 base licenses
C. The primary Cisco WLC is already set as the secondary unit
D. SSO needs to be enabled
Question 99
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.
E. Full bandwidth of all links is available.
F. Ports are grouped into multiple LAGs.
Question 100
Which CLI command does an engineer use to validate that the redundancy peer of a Stateful Switchover pair of controllers is up and connected?
A. rping
B. ping
C. eping
D. mping
