300-430 Question 24
Select 3An enterprise wants to deploy a wireless network for remote branch offices with split tunneling to optimize traffic flow and ensure fault tolerance. The IT team wants to prioritize local internet breakout for non-corporate traffic while ensuring critical corporate traffic is sent back to the data center. Which of the following configurations would best achieve this requirement?
- A
Configure local breakout for internet traffic and route corporate traffic through the tunnel to the data center.
- B
Enable centralized data forwarding for all traffic to ensure all traffic passes through the data center.
- C
Implement policy-based routing to segregate and route specific traffic types based on application and destination.
- D
Disable split tunneling and route all traffic through the corporate VPN to simplify configuration.
- E
Ensure branch office wireless controllers are configured with redundant WAN uplinks for fault tolerance.
Show answer and explanation
Correct answers: A, C, E
Explanation
Split tunneling is used to optimize traffic flow by sending non-corporate traffic directly to the internet while routing corporate traffic back to the data center. Configuring local breakout for internet traffic, implementing policy-based routing, and ensuring fault tolerance through redundant WAN uplinks fulfill the requirements for this scenario. Centralized forwarding or disabling split tunneling would increase latency and are not aligned with the goals of optimizing traffic flow and ensuring fault tolerance.
- A. Correct.
This option aligns with the split tunneling concept, allowing non-corporate traffic to exit locally while directing corporate traffic back to the data center using the tunnel.
- B. Incorrect.
This option contradicts the principles of split tunneling because centralized forwarding sends all traffic to the data center, increasing latency and reducing efficiency.
- C. Correct.
Policy-based routing allows the enterprise to segregate traffic effectively, ensuring split tunneling works as intended by routing traffic based on its type and destination.
- D. Incorrect.
Disabling split tunneling negates the purpose of the configuration, as all traffic would be forwarded to the data center, leading to inefficiencies.
- E. Correct.
Fault tolerance can be ensured by configuring redundant WAN uplinks, which is critical for maintaining connectivity in case of link failure.
