300-430 Question 22
Select 3An enterprise has deployed a Cisco FlexConnect architecture for its branch offices. The IT team wants to ensure that critical branch traffic, such as voice and video, is prioritized locally without routing through the central data center. Additionally, they want to ensure fault tolerance in case the WAN link connecting the branch to the central site fails. Which configuration should the IT team implement?
- A
Enable Split Tunneling for specific SSIDs and configure local switching for branch traffic.
- B
Configure the remote branch APs to operate in Standalone mode during WAN failures.
- C
Set up a centralized controller for all traffic to optimize resource usage.
- D
Disable Split Tunneling to ensure all traffic is routed to the central controller for security.
- E
Prioritize branch traffic using QoS policies on the local APs.
Show answer and explanation
Correct answers: A, B, E
Explanation
To achieve the enterprise's goals of prioritizing critical branch traffic and ensuring fault tolerance, the IT team should enable Split Tunneling to locally switch critical traffic, configure branch APs to operate in Standalone mode during WAN failures, and use QoS policies to prioritize critical traffic. These configurations ensure optimal performance and network availability even during WAN disruptions.
- A. Correct.
Correct: Enabling Split Tunneling allows specific traffic, such as voice and video, to be switched locally at the branch, while other traffic can still be routed to the central controller. This improves performance and reduces latency for critical applications.
- B. Correct.
Correct: Configuring branch APs to operate in Standalone mode ensures that the Wi-Fi network remains functional even if the WAN link to the central site fails. This is essential for fault tolerance.
- C. Incorrect.
Incorrect: Using a centralized controller for all traffic increases dependency on the WAN link and can lead to higher latency and potential service interruptions during WAN failures.
- D. Incorrect.
Incorrect: Disabling Split Tunneling forces all traffic to the central controller, which contradicts the goal of prioritizing local traffic and ensuring fault tolerance.
- E. Correct.
Correct: QoS policies on local APs help prioritize critical traffic like voice and video, ensuring better performance for these applications at the branch level.
