300-425 Question 25
Select 3A retail company has deployed a centralized wireless network where branch office traffic is tunneled back to the data center using a centralized controller. However, the company wants to optimize traffic flow for specific applications like video conferencing and reduce latency issues for branch users. They also want to ensure network connectivity in case the central controller becomes unavailable. What configuration should be implemented to meet these requirements?
- A
Enable split tunneling on the branch access points for local breakout of specific application traffic.
- B
Configure a secondary controller as a backup in the event of central controller failure.
- C
Disable split tunneling to ensure all traffic is routed through the centralized controller.
- D
Implement QoS policies on the centralized controller to prioritize video conferencing traffic.
- E
Configure FlexConnect mode on branch access points to enable local switching.
Show answer and explanation
Correct answers: A, B, E
Explanation
To meet the requirements, split tunneling should be enabled to optimize specific application traffic, and FlexConnect mode should be configured on branch access points to allow local switching. Additionally, a secondary controller should be configured to ensure fault tolerance in case the central controller becomes unavailable. These configurations collectively address the needs for optimized traffic flow and network resiliency.
- A. Correct.
Enabling split tunneling allows specific application traffic, such as video conferencing, to break out locally at the branch, reducing latency and optimizing performance.
- B. Correct.
Configuring a secondary controller as a backup ensures fault tolerance by allowing the branch network to remain operational even if the primary controller fails.
- C. Incorrect.
Disabling split tunneling forces all traffic to be routed through the centralized controller, increasing latency and contradicting the requirement to optimize traffic flow for specific applications.
- D. Incorrect.
Implementing QoS policies on the centralized controller helps prioritize traffic but does not address the requirement to reduce latency by optimizing traffic flow locally.
- E. Correct.
FlexConnect mode on branch access points enables local switching, which is necessary for split tunneling and maintaining local connectivity during controller failure.
