A Certkiller network is shown in the exhibit below:The routers in this network are running RIPv2. Which addressing scheme would satisfy the needs of this network yet waste the fewest addresses?



A. Network 1: 192.168.10.0/26Network 2: 192.168.10.64/26Network 3: 192.168.10.128/26Serial link 1: 192.168.20.0/24Serial link 2: 192.168.30.0/24
B. Network 1: 192.168.10.0/26Network 2: 192.168.10.64/28Network 3: 192.168.10.80/29Serial link 1: 192.168.10.88/30Serial link 2: 192.168.10.96/30
C. Network 1: 192.168.10.0/26Network 2: 192.168.10.64/27Network 3: 192.168.10.96/28Serial link 1: 192.168.10.112/30Serial link 2: 192.168.10.116/30

Network 1: 192.168.10.0/26network 2: 192.168.10.64/27network 3: 192.168.10.96/28serial link 1: 192.168.10.112/30serial link 2: 192.168.10.116/30-required number of hosts :50 when we use the 26 bits for network : 11111111.11111111.11111111.11000000 so 62 usable host can be in one network. 50 host for now and remaining hosts address for further growth. network 2 required number of hosts: 20when we use the 27 bits for network: 11111111.11111111.1111111.11100000 so 30 usable hosts can be in one network. network 3 required number of hosts: 10when we use the 28 bits for network: 11111111.11111111.11111111.11110000 so 14 usable hosts can be in one network. connection between ck1 , ck2 and ck3 is wan so when you use 30 bits network ip, you will not lose any ip addresses from network since this subnet allows for only 2 host addresses.
