200-301 Question 262
Single answerA network administrator is analyzing a router's routing table and sees the following entry: 'O 192.168.10.0/24 [110/2] via 10.1.1.1, 00:00:12, GigabitEthernet0/1'. What does the '[110/2]' indicate in this routing table entry?
- A
The administrative distance (AD) and metric of the route
- B
The subnet mask and prefix length of the route
- C
The route's cost and bandwidth of the interface
- D
The age of the route in seconds and its reliability
Show answer and explanation
Correct answer: A
Explanation
In a routing table entry, '[AD/Metric]' indicates the administrative distance and metric for the route. The administrative distance (110 in this case) is a measure of the trustworthiness of the route source, while the metric (2) represents the cost to reach the destination based on the routing protocol's criteria. The additional details, such as the age ('00:00:12') and the interface ('GigabitEthernet0/1'), are separate components of the routing table entry.
- A. Correct.
Correct. '[110/2]' represents the administrative distance (110) and the metric (2) of the route. The AD indicates the trustworthiness of the route source, and the metric reflects the cost of reaching the destination.
- B. Incorrect.
Incorrect. The subnet mask and prefix length are represented by the '/24' in '192.168.10.0/24', not the '[110/2]'.
- C. Incorrect.
Incorrect. The cost (metric) is part of '[110/2]', but this code does not include the bandwidth of the interface.
- D. Incorrect.
Incorrect. '[110/2]' does not indicate the age or reliability of the route. The age of the route is shown separately as '00:00:12'.
