NEW QUESTION 32
A customer asks an engineer to explain the concept of mobility domains and mobility groups. Which statement does the engineer respond with?
- 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 are 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. 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.
