Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 49

When a wireless client roams between two different wireless controllers, a network connectivity outage is experienced for a period of time.
Which configuration issue would cause this problem?

Answer options

• A. Not all of the controllers in the mobility group are using the same mobility group name.
• B. Not all of the controllers within the mobility group are using the same virtual interface IP address.
• C. All of the controllers within the mobility group are using the same virtual interface IP address.
• D. All of the controllers in the mobility group are using the same mobility group name.

Correct answer: B

Explanation

The correct answer is B because if the controllers do not share the same virtual interface IP address, the client cannot maintain a seamless connection during roaming, leading to a connectivity outage. Options A and D are incorrect as they pertain to mobility group names, which do not directly impact connectivity during roaming. Option C is also incorrect since having the same virtual interface IP address would support connectivity, not hinder it.
