Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 69

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

Answer options

• 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.

Correct answer: C

Explanation

Answer C is correct because it accurately states that WLCs in the same mobility domain can communicate and that mobility groups do limit the sharing of security context and AP fail-over. The other options either incorrectly describe the communication requirements or misrepresent the role of mobility groups.
