300-415 Question 116
Select 3A network engineer is configuring the Cisco SD-WAN data plane for a branch site that requires direct internet access (DIA) for certain applications while ensuring other traffic routes through the corporate data center. Which of the following configurations are required to achieve this?
- A
Create a centralized data policy to match application traffic and route it directly to the internet.
- B
Enable NAT on the branch site's WAN Edge router to allow internet-bound traffic.
- C
Configure a localized control policy to prioritize traffic destined for the corporate data center.
- D
Define a TLOC extension to forward internet traffic through a neighboring site with internet access.
- E
Apply an App-Aware Routing policy to steer specific application traffic based on SLA requirements.
Show answer and explanation
Correct answers: A, B, E
Explanation
To configure the Cisco SD-WAN data plane for a branch site requiring Direct Internet Access (DIA), a centralized data policy is needed to define internet-bound traffic. NAT is essential for address translation, and App-Aware Routing ensures application traffic meets SLA requirements. Localized control policies and TLOC extensions are not relevant to directing internet traffic in this scenario.
- A. Correct.
Correct: A centralized data policy is required to identify specific application traffic and define actions, such as routing it directly to the internet.
- B. Correct.
Correct: NAT must be enabled on the branch site's WAN Edge router to translate private IP addresses to public IP addresses for internet-bound traffic.
- C. Incorrect.
Incorrect: A localized control policy is used to influence routing decisions for control plane routes, not for data plane traffic steering.
- D. Incorrect.
Incorrect: A TLOC extension is used to extend transport locator reachability between devices, not for directing DIA traffic at the branch site.
- E. Correct.
Correct: App-Aware Routing allows for traffic steering based on SLA requirements, ensuring that specific application traffic can be routed appropriately.
