Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable the HTTP/HTTPS server on the device
To enable RESTCONF on Cisco IOS XE, the following are required: enable the HTTP/HTTPS server (option B) to allow RESTCONF communication; enable the 'restconf' feature (option C) to activate RESTCONF services; and enable the 'netconf-yang' feature (option E) because RESTCONF relies on the YANG infrastructure provided by netconf-yang. Option A is incorrect because RESTCONF can use any YANG model, not only Cisco native models. Option D is incorrect because the RESTCONF API endpoint is '/restconf', not '/rest'.
