Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
set routing-options gres enable
Why it's wrong here
GRES is configured under the chassis hierarchy, not routing-options.
- ✗
set interfaces redundancy gres
Why it's wrong here
Interfaces hierarchy does not control GRES.
- ✓
set chassis redundancy graceful-switchover
Why this is correct
This command enables GRES on the chassis, allowing control plane state synchronization to support seamless routing engine failovers.
- ✗
set system graceful-restart
Why it's wrong here
System graceful-restart configures protocol restart helper/restart behavior, not chassis-level GRES.
