Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
0
Why this is correct
A directly connected interface route carries a default administrative distance of 0, the lowest value Cisco assigns. This reflects its status as the most trustworthy source: the router knows the destination is reachable on a locally attached link, so no competing route from another protocol should ever override it.
- ✗
1
Why it's wrong here
Administrative distance 1 belongs to static routes, not connected interface routes, so this value misstates the default. It is tempting because static routes are also highly trusted, and 1 would be correct when identifying the default distance assigned to a manually configured static route.
- ✗
5
Why it's wrong here
Distance 5 is assigned to EIGRP summary routes, not directly connected interface routes. It is tempting because it is a low, trusted value, and would be correct when identifying the administrative distance Cisco assigns to a summary route generated by EIGRP.
- ✗
110
Why it's wrong here
Distance 110 belongs to OSPF, a dynamic routing protocol, not a directly connected interface route. It is tempting because OSPF is widely deployed, and 110 would be correct when identifying the default administrative distance assigned to routes learned through OSPF.
