300-425 Question 20
Single answerA retail organization has a distributed wireless network with multiple branch locations. Each branch is connected to the central data center via a WAN link. To ensure seamless client roaming within each branch location without relying on the central WLC, the organization has configured FlexConnect groups. Which of the following statements is true about client roaming in this scenario?
- A
Client roaming between APs in the same FlexConnect group at a branch is handled locally without requiring the central WLC.
- B
Client roaming between APs in different FlexConnect groups at the same branch requires coordination with the central WLC.
- C
FlexConnect groups are not relevant to client roaming and are only used for AP configuration synchronization.
- D
Client roaming across branches is managed locally by the FlexConnect groups without involving the central WLC.
Show answer and explanation
Correct answer: A
Explanation
FlexConnect groups are designed to enhance wireless network efficiency in distributed environments by enabling local switching and seamless roaming within the same group. This reduces the dependency on the central WLC, especially across unreliable WAN links. However, roaming across FlexConnect groups or across different branches still requires coordination with the central WLC.
- A. Correct.
This is correct. FlexConnect groups allow for seamless client roaming between APs in the same group at a branch without relying on the central WLC, which is particularly useful when the WAN link to the central site is unreliable or has high latency.
- B. Incorrect.
This is incorrect. Roaming between different FlexConnect groups, even within the same branch, requires coordination with the central WLC as the groups operate independently.
- C. Incorrect.
This is incorrect. FlexConnect groups are highly relevant to client roaming as they enable local switching and roaming within the same group, reducing dependency on the central WLC.
- D. Incorrect.
This is incorrect. Client roaming across branches cannot be managed locally by FlexConnect groups because these groups are limited to local branch operations. Roaming across branches requires the central WLC.
