Computer Networks C5

The first byte of an IP address is 11100001. Which class does it belong to?

• Class B

• Class C

• Class D

• Class E

In a TCP/IP network using Subnet Mask 255.255.255.0, which pair of computers can communicate with each other?

• 192.168.1.3 and 192.168.100.1

• 192.168.15.1 and 192.168.15.254

• 192.168.100.15 and 192.186.100.16

• 172.25.11.1 and 172.26.11.2

Given the address 192.64.10.0/28, determine the number of subnets and hosts per subnet:

• 6 subnets, 30 hosts per subnet

• 14 subnets, 14 hosts per subnet

• 16 subnets, 16 hosts per subnet

• 8 subnets, 32 hosts per subnet

A Class B network needs to be divided into 3 subnets. Which Subnet Mask should be used?

• 255.255.224.0

• 255.0.0.255

• 255.255.192.0

• 255.255.255.224

Based on the output of the route print command, Machine X has an IP address of:

• 0.0.0.0

• 172.16.9.12

• 127.0.0.1

• 172.16.9.0

Which IP addresses are in the same subnet as 131.107.2.56/28?

• From 131.107.2.48 to 131.107.2.63

• From 131.107.2.49 to 131.107.2.63

• From 131.107.2.48 to 131.107.2.62

• From 131.107.2.55 to 131.107.2.126

Which IP address shares the same subnet as 192.168.1.10/24?

• 192.168.10.1/24

• 192.168.1.256/24

• 192.168.11.12/24

• 192.168.1.33/24

To determine which address class an IP belongs to, you should look at:

• The value of the first byte (octet)

• The ARP protocol

• The number of dots in the address

• The DHCP address

A Class C address is divided into 5 subnets. What is the required Subnet Mask?

• 255.255.255.224

• 255.255.255.252

• 255.255.255.240

• 255.255.255.248

In IPv4, there are 5 address classes: A, B, C, D, E. Class C ranges from:

• 224.0.0.0 to 239.255.255.255

• 192.0.0.0 to 223.255.255.255

• 128.0.0.0 to 191.255.255.255

• 240.0.0.0 to 255.255.255.255
