300-415 Question 91
Select 3An enterprise is deploying Cisco SD-WAN across multiple branch locations. To ensure network scalability and redundancy, they decide to use multiple vSmart controllers. Which of the following statements about the deployment is correct?
- A
vSmart controllers distribute routing policies and key material to WAN Edge devices.
- B
All WAN Edge devices must actively connect to every vSmart controller in the deployment.
- C
Using multiple vSmart controllers provides both scalability and redundancy.
- D
If a vSmart controller fails, WAN Edge devices will automatically reconnect to another available vSmart controller.
Show answer and explanation
Correct answers: A, C, D
Explanation
In a Cisco SD-WAN deployment, vSmart controllers play a critical role in distributing policies and securing communication. Using multiple vSmart controllers enhances scalability by balancing the workload and ensures redundancy in case one controller fails, allowing the system to maintain seamless operations by redirecting WAN Edge connections to available controllers.
- A. Correct.
Correct: vSmart controllers are responsible for distributing routing policies and cryptographic key material to the WAN Edge devices in the SD-WAN fabric.
- B. Incorrect.
Incorrect: While WAN Edge devices establish connections with multiple vSmart controllers, they do not need to actively connect to every vSmart controller simultaneously. Connections are handled dynamically based on the configuration and availability.
- C. Correct.
Correct: Deploying multiple vSmart controllers ensures scalability by distributing load and redundancy in case of failure.
- D. Correct.
Correct: When a vSmart controller fails, WAN Edge devices are designed to automatically reconnect to another available vSmart controller to maintain network operations.
