Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Mismatched failover link configuration or physical layer issues.
Why this is correct
Physical or configuration mismatch on the failover port prevents the link from forming.

The primary unit is in routed mode.
Why it's wrong here
Mode type does not affect the failover link physical status.

The standby unit has an expired license.
