Question 4

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 15

An enterprise is using the wireless network as the main network connection for corporate users and guests. To ensure wireless network availability, two standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but fails. Which protocol needs to be allowed between the networks that the controllers are installed?
