Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
<edit-config> on candidate, then <copy-config> to running
Why it's wrong here
Cisco uses <commit> instead of <copy-config>.
- ✓
<lock>, <edit-config> on candidate, <commit>, <unlock>
Why this is correct
This is the standard candidate config workflow.
- ✗
<edit-config> on running, no lock needed
Why it's wrong here
Editing running directly is not supported on IOS XR; candidate model is used.
- ✗
<lock>, <edit-config>, <commit>, <unlock>
Why it's wrong here
IOS XR uses candidate config; <commit> is needed after <edit-config>.
