Review Questions - Chapter 4 Easy Subnetting

1. What is the maximum number of IP addresses that can be assigned to hosts on a local subnet that uses the 255.255.255.224 subnet mask

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?

What is the subnetwork address for a host with the IP address 200.10.5.68/28?

The network address of 172.16.0.0/19 provides how many subnets and hosts?

If a host on a network has the address 172.16.45.14/30, what is the subnetwork this host belongs to?

Which mask should you use on point-to-point links in order to reduce the waste of IP addresses?

What is the subnetwork number of a host with an IP address of 172.16.66.0/21?

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?

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?

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?

You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use?

You configure a router interface with the IP address 192.168.10.62 255.255.255.192 and
receive the following error:

Bad mask /26 for address 192.168.10.62

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 interface?

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.

You have a network in your data center that needs 310 hosts. Which mask should you use so you waste the least amount of addresses?

You have a network with a host address of 172.16.17.0/22. From the following options, which is another valid host address in the same subnet?

Given an IP address 172.16.28.252 with a subnet mask of 255.255.240.0, what is the correct network address?
