Which two statements describe the IP address 10.16.3.65/23? (Choose two.)
The subnet address is 10.16.3.0 255.255.254.0.
The lowest host address in the subnet is 10.16.2.1 255.255.254.0.
The last valid host address in the subnet is 10.16.2.254 255.255.254.0.D. The broadcast
address of the subnet is 10.16.3.255 255.255.254.0.
The network is not subnetted.

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?
192.168.19.0 255.255.255.0
192.168.19.33 255.255.255.240
192.168.19.26 255.255.255.248
192.168.19.31 255.255.255.248
192.168.19.34 255.255.255.240
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
192.168.192.255
You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use?
255.255.255.192
255.255.255.224
255.255.255.240
255.255.255.248
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
Why did you receive this error?
You typed this mask on a WAN link and that is not allowed.
This is not a valid host and subnet mask combination.
ip subnet-zero is not enabled on the router.
The router does not support IP.
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?
172.16.112.0
172.16.96.0
172.16.255.0
172.16.128.0
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.
192.168.10.142
192.168.10.66
192.168.100.254
192.168.10.143
192.168.10.126
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
