200-301 Question 263
Single answerA network engineer is reviewing the routing table on a router and notices the following entry:
O 192.168.10.0/24 [110/2] via 192.168.1.1, 00:00:15, GigabitEthernet0/0
Which component of the routing table entry represents the administrative distance?
- A
O
- B
192.168.10.0/24
- C
110
- D
2
- E
GigabitEthernet0/0
Show answer and explanation
Correct answer: C
Explanation
The administrative distance (AD) is a value used by routers to rank the trustworthiness of different routing sources. In the routing table entry provided, the AD is represented by the number 110. This value is specific to the OSPF protocol and is used by the router to prioritize routes from multiple routing sources.
- A. Incorrect.
This indicates the routing protocol used (in this case, OSPF) and does not represent the administrative distance.
- B. Incorrect.
This represents the destination network and subnet mask, not the administrative distance.
- C. Correct.
This is the administrative distance, which indicates the trustworthiness of the route source.
- D. Incorrect.
This value represents the metric, which is used to determine the best path, not the administrative distance.
- E. Incorrect.
This specifies the outgoing interface for the route, not the administrative distance.
