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 packet is silently dropped without any notification.
Why it's wrong here
Silent drops are performed by 'discard', not 'reject'.
- ✗
The packet is forwarded to the default gateway.
Why it's wrong here
Reject is a termination action, not a forwarding action.
- ✓
An ICMP destination unreachable message is sent back to the packet source.
Why this is correct
Reject returns an ICMP unreachable message.
- ✓
The route is installed into the forwarding table.
Why this is correct
Reject static routes are actively installed into the PFE forwarding table.
- ✗
The packet is tagged with an MPLS label.
Why it's wrong here
Reject routes do not add MPLS labels.
