Which two statements describe the IP address 10.16.3.65/23? (Choose two.)

A. The subnet address is 10.16.3.0 255.255.254.0.

B. The lowest host address in the subnet is 10.16.2.1 255.255.254.0.

C. 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.

E. The network is not subnetted.

Solution

Ans: B. The lowest host address in the subnet is 10.16.2.1 255.255.254.0

10.16.3.65/23

Length of net id: 23 bits

00001010 00001000 00000011 010000001

00001010 00001000 0000001 : 101000001

Network address: 00001010 00001000 00000010 00000000
               = 10.16.2.0

So, the lowest host address: 10.16.2.1

Subnet Mask: 11111111 11111111 11111110 00000000
           = 255:255.254.0
