CCNA subnetting questions
A. Network A – 172.17.3.48/26
B. Network A – 172.17.3.128/25
C. Network A – 172.17.3.192/26
D. Link A – 172.17.3.0/30
E. Link A – 172.17.3.40/30
F. Link A – 172.17.3.112/30
Answer: B D
Explanation
Network A connects 120 hosts. /25 will be the best because it offers 126 usable host IP addresses (follow the cram table above)
The ip subnet-zero command can be used for link A network 172.16.3.0/30. Other /30 IP addresses in the option above are a waste of ip addresses and not hierarchical in structure.
