300-435 Question 236
Single answerA network administrator is automating Cisco SD-WAN operations and wants to apply a centralized QoS policy to prioritize voice traffic across all branch sites. The administrator uses Cisco vManage to configure the policy. Which step is essential to ensure the policy is applied to the required devices in the network?
- A
Define the QoS policy under the device template configuration
- B
Attach the QoS policy to the centralized data policy and apply it to the site list
- C
Configure the QoS policy on individual branch devices via CLI
- D
Enable the QoS policy under the application-aware routing configuration
Show answer and explanation
Correct answer: B
Explanation
In Cisco SD-WAN, centralized policies such as QoS are configured via vManage and attached to centralized data policies to ensure consistent deployment across the network. By applying the policy to a defined site list, the administrator ensures the QoS rules are enforced on the intended devices without manual configuration on individual devices.
- A. Incorrect.
Defining the QoS policy under the device template configuration does not centralize the policy implementation or ensure it is applied across all branch sites.
- B. Correct.
Attaching the QoS policy to the centralized data policy and applying it to the site list is the correct method to ensure the policy is centrally managed and applied consistently across the required devices.
- C. Incorrect.
Configuring the QoS policy on individual branch devices via CLI defeats the purpose of centralized management and automation in Cisco SD-WAN.
- D. Incorrect.
Enabling the QoS policy under the application-aware routing configuration is not relevant to applying a centralized QoS policy across the network.
