Cisco 200-125 Exam
Refer to the exhibit. Which address range efficiently summarizes the routing table of the addresses for router Main?
- A. 172.16.0.0./21
- B. 172.16.0.0./20
- C. 172.16.0.0./16
- D. 172.16.0.0/18
Answer: Option B.
Explanation:
The 172.16.0.0./20 network is the best option as it includes all networks from 172.16.0.0 – 172.16.16.0 and does it more efficiently than the /16 and /18 subnets.
The /21 subnet will not include all the other subnets in this one single summarized address.
