Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Directly modify the startup configuration file on the hard disk.
Why it's wrong here
Configuration changes go through the candidate datastore, not direct raw disk editing.

Why this is correct
Interface operational statistics are accessible via operational REST paths.
- ✓
Retrieve system hardware and software inventory details.
Why this is correct
System operational data can be retrieved via GET requests.
- ✗

Why it's wrong here

- ✓
Execute custom operational RPCs like 'get-route-information'.
Why this is correct
Custom RPCs can be executed via the operational RPC endpoints.
