Correct answer & explanation
✓

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To clear operational state counters such as interface packet counters.
Why it's wrong here
Operational clearing requires RPC execution, not configuration object deletion.
- ✗
To terminate an active REST API session and revoke the auth token.
Why it's wrong here
Sessions are stateless or managed via standard HTTP connection teardown; DELETE targets resources.
- ✓
To delete a specific configuration hierarchy or statement from the candidate configuration.
Why this is correct
HTTP DELETE maps to deleting configuration elements in the candidate datastore.
- ✗
To discard the entire candidate configuration.
Why it's wrong here
Discarding the entire configuration is done via a specific RPC call, not a generic resource DELETE.
