NEW QUESTION # 143
An SR-MPLS Policy needs to divert service traffic to a tunnel for forwarding. If traffic from various services is destined for the same address, which of the following traffic diversion modes is recommended to ensure the quality of each service?
Answer: B
Explanation:
Traffic Diversion in SR-MPLS Policy
SR-MPLS Policiesuse traffic steering mechanismsto direct specific flows toSegment Routing paths (SR Policies). When multiple services share thesame destination address,color-based traffic diversionensuresdifferentiated service treatment.
#B. Color-based traffic diversion (Correct Answer)
Traffic is classified based on "color" (a BGP-SR policy attribute) and mapped to different SR-MPLS tunnels.
Different colors represent different paths(e.g., high-priority services can use an optimized low-latency path).
This method ensures service qualityby directing traffic according topolicy-based routing decisions.

replace: Replaces the existing configuration with the new one.
create (C): Creates a new configuration node, but will fail if the node already exists.
delete: Deletes an existing configuration node.
remove (A): Removes an existing node, but if the node does not exist, it will not generate an error.
The attribute "update" (D) is not a valid NETCONF operation attribute.
D is the correct answer as it does not exist within the NETCONF operation attribute set.
