300-430 Question 6
Single answerAn organization has deployed Cisco FlexConnect for their branch office wireless network. The branch office experiences WAN link failures occasionally, and the IT administrator wants to ensure that the wireless clients can continue accessing local resources during such outages. Which FlexConnect operating mode and switching mode combination should the administrator configure to meet this requirement?
- A
Centralized switching with connected mode
- B
Centralized switching with standalone mode
- C
Local switching with connected mode
- D
Local switching with standalone mode
Show answer and explanation
Correct answer: D
Explanation
FlexConnect operating modes (connected and standalone) determine whether the AP requires connectivity to the controller for operation. Switching modes (centralized and local) dictate whether client traffic is tunneled to the controller or switched locally. In this case, 'local switching' ensures client traffic remains within the branch office, and 'standalone mode' allows the AP to operate independently of the controller during WAN failures. Therefore, 'local switching with standalone mode' is the correct configuration.
- A. Incorrect.
Centralized switching with connected mode requires the WAN link to be active because all client traffic is tunneled back to the central controller. This does not meet the requirement for continued access during WAN outages.
- B. Incorrect.
Centralized switching with standalone mode is not a valid configuration since FlexConnect centralized switching relies on connectivity to the WAN and central controller.
- C. Incorrect.
Local switching with connected mode allows traffic to be locally switched at the branch office, but the connected mode requires the WAN link to remain active for the controller to manage the APs.
- D. Correct.
Local switching with standalone mode allows traffic to be locally switched at the branch office and enables the AP to continue functioning even during WAN failures, meeting the requirement.
