200-301 Question 264
Select 4A network engineer examines the routing table of a router and notices the following entry: 'O 192.168.1.0/24 [110/2] via 10.1.1.1, 00:00:12, FastEthernet0/0'. Which of the following statements accurately interpret components of this routing table entry?
- A
The route was learned through the OSPF routing protocol.
- B
The administrative distance for this route is 2.
- C
The next-hop IP address for this route is 10.1.1.1.
- D
The FastEthernet0/0 interface is used to reach the destination network.
- E
The routing protocol has the default administrative distance set to 110.
Show answer and explanation
Correct answers: A, C, D, E
Explanation
This routing table entry provides information about how the route to the 192.168.1.0/24 network was learned (via OSPF), the administrative distance (110), the metric (2), the next-hop IP address (10.1.1.1), and the outgoing interface (FastEthernet0/0). Understanding these components is crucial for interpreting and troubleshooting network routing.
- A. Correct.
Correct. The 'O' symbol indicates that the route was learned via OSPF (Open Shortest Path First) routing protocol.
- B. Incorrect.
Incorrect. The '[110/2]' indicates an administrative distance of 110 and a metric (cost) of 2, not an administrative distance of 2.
- C. Correct.
Correct. The 'via 10.1.1.1' specifies that the next-hop IP address for this route is 10.1.1.1.
- D. Correct.
Correct. The 'FastEthernet0/0' indicates the outgoing interface used to forward packets to the destination network.
- E. Correct.
Correct. OSPF has a default administrative distance of 110, which is reflected in the routing table entry.
