The input service policy shown in the exhibit matches traffic with DSCP value 1 and applies a QoS set action to rewrite that marking to DSCP 63. Therefore, packets entering interface Fa7/0/2 with DSCP 1 are remarked to DSCP 63, making option B correct. The second part of the configuration defines a class map matching DSCP 63 and a policy map using bandwidth percent 50. That behavior belongs to class-based queuing/scheduling, where DSCP63-marked traffic is placed into a class that receives a bandwidth allocation. In the given option set, option C best represents this queuing behavior. Option D is wrong because the service policy explicitly changes the DSCP value. Option E is not accurate because classification is not triggered by reaching 50 percent bandwidth; classification occurs by matching packet fields such as DSCP. Option A is less precise than C because the shown policy behavior is class-based queuing with a bandwidth allocation. The important ENCOR concept is the separation between marking on ingress and queuing/scheduling on egress.

In Cisco SD-Access, the fabric roles are clearly separated. The fabric edge node connects endpoints to the fabric and encapsulates user traffic into VXLAN. The control plane node runs the LISP control-plane function and maintains the endpoint ID to routing locator mapping database. That makes option C correct. The border node connects the SD-Access fabric to external networks, such as the data center, WAN, internet edge, or shared services. Therefore, the border node is required when fabric endpoints must communicate with nonfabric resources, which makes option B correct. Option A is wrong because the full endpoint mapping database belongs to the control plane node, not the border node. Option D is wrong because endpoints connect to fabric edge nodes, not normally to border nodes. Option E is also wrong because the control plane node is not in the data-forwarding path for normal user traffic; it resolves mappings. Data traffic flows through the fabric using VXLAN encapsulation after control-plane resolution.
