300-435 Question 237
Single answerAn organization has deployed Cisco SD-WAN in their network and is using vManage to configure and monitor their environment. The network administrator is tasked with creating a data policy to route specific application traffic over a preferred transport link based on performance metrics like latency and packet loss. Which feature in Cisco SD-WAN should the administrator use to achieve this?
- A
Localized data policy
- B
Application-aware routing
- C
Service chaining
- D
Control policy
Show answer and explanation
Correct answer: B
Explanation
Application-aware routing in Cisco SD-WAN enables routing decisions based on real-time performance metrics collected from the network. This allows administrators to define policies that route specific application traffic over the most optimal transport link, ensuring improved application performance and user experience. In this scenario, the administrator must use application-aware routing to meet the requirement of routing traffic based on latency and packet loss metrics.
- A. Incorrect.
Localized data policy is used to enforce policies locally on a device, such as access control lists or route policies, but it does not handle application-based routing decisions.
- B. Correct.
Application-aware routing is the correct feature to use as it allows routing decisions based on real-time application performance metrics like latency, jitter, and packet loss.
- C. Incorrect.
Service chaining is used to chain traffic through specific network services, such as firewalls or load balancers, but it is unrelated to routing decisions based on application performance.
- D. Incorrect.
Control policy is used to influence routing decisions at the control plane level, such as determining which routes are advertised or accepted, but it does not manage data plane traffic routing based on performance.
