Networking - Subnetting Question and Answer
Networking - Subnetting Question and Answer
11. You have an interface on a router with the IP address of 192.168.192.10/29. What is the broadcast address the hosts will use on this LAN?
- 192.168.192.15
- 192.168.192.31
- 192.168.192.63
- 192.168.192.127
12. You have a network with a subnet of 172.16.17.0/22. Which is the valid host address?
- 172.16.17.1 255.255.255.252
- 172.16.0.1 255.255.240.0
- 172.16.20.1 255.255.254.0
- 172.16.18.255 255.255.252.0
13. On a VLSM network, which mask should you use on point-to-point WAN links in order to reduce the waste of IP addresses?
- /27
- /28
- /29
- /30
14. To test the IP stack on your local host, which IP address would you ping?
- 127.0.0.0
- 1.0.0.127
- 127.0.0.1
- 127.0.0.255
15. If a host on a network has the address 172.16.45.14/30, what is the subnetwork this host belongs to?
- 172.16.45.0
- 172.16.45.4
- 172.16.45.8
- 172.16.45.12
16. Which configuration command must be in effect to allow the use of 8 subnets if the Class C subnet mask is 255.255.255.224?
- Router(config)#ip classless
- Router(config)#no ip classful
- Router(config)#ip unnumbered
- Router(config)#ip subnet-zero
17. Using the illustration from the previous question, what would be the IP address of S0 if you were using the first subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP address in the range. Again, the zero subnet should not be considered valid for this question.
- 192.168.10.24
- 192.168.10.62
- 192.168.10.30
- 192.168.10.127
18. What is the subnetwork address for a host with the IP address 200.10.5.68/28?
- 200.10.5.56
- 200.10.5.32
- 200.10.5.64
- 200.10.5.0
