Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The entire target configuration datastore is replaced by the configuration provided in the RPC payload.
Why this is correct
Setting default-operation to replace completely overwrites the existing datastore content.
- ✗
The configuration is merged, and any conflicting nodes generate a validation error.
Why it's wrong here
This does not describe the replace operation behavior.
- ✗
The candidate datastore is cleared, and only the default factory configuration is loaded.
Why it's wrong here
Clearing the configuration requires a specific load operation or clear command.
- ✗
Only the specific leaf nodes provided in the RPC are updated; everything else remains intact.
Why it's wrong here
That describes the merge operation, which is the default.
