Q.1.
If a host on a network has the address 172.16.45.14/30, what is the subnetwork this host belongs to?
Q.2.
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?
Q.3.
Using the illustration from the previous question, what would be the IP address of SO 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.
Q.4.
What is the subnetwork address for a host with the IP address 200.10.5.68/28?
Q.5.
You need to configure a server that is on the subnet 192.168.19.24/29. The router has the first available host address. Which of the following should you assign to the server?
Q.6.
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?
Q.7.
You have a network with a subnet of 172.16.17.0/22. Which is the valid host address?
Q.8.
You have a network that needs 29 subnets while maximizing the number of host addresses available on each subnet. How many bits must you borrow from the host field to provide the correct subnet mask?
Q.9.
On a VLSM network, which mask should you use on point-to-point WAN links in order to reduce the waste of IP addresses?
Q.10.
To test the IP stack on your local host, which IP address would you ping?
Q.11.
If an Ethernet port on a router were assigned an IP address of 172.16.112.1/25, what would be the valid subnet address of this host?
Q.12.
You have an interface on a router with the IP address of 192.168.192.10/29. Including the router interface, how many hosts can have IP addresses on the LAN attached to the router interface?
Q.13.
What is the subnetwork number of a host with an IP address of 172.16.66.0/21?
Q.14.
The network address of 172.16.0.0/19 provides how many subnets and hosts?
Q.15.
Using the following illustration, what would be the IP address of E0 if you were using the eighth subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP address in the range. The zero subnet should not be considered valid for this question.
