300-430 Question 15
Single answerAn enterprise network is deploying FlexConnect mode to support branch offices with limited WAN bandwidth. The IT team needs to ensure that wireless clients at the branch offices can continue to authenticate locally even if connectivity to the centralized controller is lost. Which FlexConnect feature should be configured to meet this requirement?
- A
FlexConnect Local Switching
- B
FlexConnect Central Authentication
- C
FlexConnect Local Authentication
- D
FlexConnect VLAN-based Central Switching
Show answer and explanation
Correct answer: C
Explanation
FlexConnect Local Authentication is the correct answer because it allows branch access points to authenticate wireless clients locally without requiring connectivity to the centralized controller. This feature is essential for ensuring uninterrupted client access when the WAN link connecting the branch to the controller is unavailable.
- A. Incorrect.
FlexConnect Local Switching allows wireless traffic to be switched locally at the branch access point, but it does not address client authentication when the controller is unreachable.
- B. Incorrect.
FlexConnect Central Authentication requires connectivity to the centralized controller for client authentication, making it unsuitable for scenarios where the WAN link is unavailable.
- C. Correct.
FlexConnect Local Authentication enables the access points to authenticate clients locally using pre-configured credentials or cached RADIUS information, which is ideal for maintaining authentication during WAN outages.
- D. Incorrect.
FlexConnect VLAN-based Central Switching is used to centrally switch traffic for specific VLANs and does not provide local authentication capabilities.
