300-425 Question 12
Single answerYou are configuring a branch office deployment with limited WAN bandwidth. The branch office APs must continue to provide client connectivity and authentication locally even if the connection to the central controller is lost. Which FlexConnect feature should you configure to meet this requirement?
- A
FlexConnect Local Switching
- B
FlexConnect Central Authentication
- C
FlexConnect Local Authentication
- D
FlexConnect OfficeExtend Mode
Show answer and explanation
Correct answer: C
Explanation
FlexConnect Local Authentication is the appropriate feature for scenarios where APs need to continue client authentication locally when the WAN connection to the central controller is lost. This ensures uninterrupted wireless services in branch office deployments with limited WAN bandwidth.
- A. Incorrect.
FlexConnect Local Switching allows APs to switch client traffic locally, but it does not handle client authentication in the event of a WAN outage. This feature is relevant for optimizing traffic but not for maintaining authentication.
- B. Incorrect.
FlexConnect Central Authentication requires the central controller to be reachable for authentication, which does not meet the requirement of operating during a WAN outage.
- C. Correct.
FlexConnect Local Authentication enables the AP to authenticate clients locally using cached credentials or a local RADIUS server when the central controller is unreachable. This is the correct choice for ensuring continued client connectivity and authentication during a WAN outage.
- D. Incorrect.
FlexConnect OfficeExtend Mode is designed for providing secure remote access for teleworkers and is not relevant to this branch office scenario.
