Question 7

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

Options:

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 8

A wireless engineer is using Ekahau site survey to validate that an existing wireless network is operating as expected, which type of survey should be using to identify the end-to-end network performance?

A.

GPS assisted

B.

Spectrum analysis

C.

Passive

D.

Active ping

Question 9

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.)

All interface traffic passes as long as one port is up.

C.

The same port has multiple untagged dynamic interfaces.

D.

Interface connection to two separate nonstacked switches is available.

E.
