Q.1. How large are IPv4 addresses?
• 8 bits
• 16 bits
• 32 bits
• 64 bits
• 128 bits

Q.2. Refer to the graphic. A user at the workstation cannot connect to the server. All cables have been tested and are working and all devices have IP addressing. However, the user cannot ping the server. What is causing the problem?
• The router interface does not have a default gateway.
• The switch does not have an IP address and default gateway.
• The workstation and server are on different logical networks.
• The workstation does not know the MAC address of the switch.

Q.3. Which part of an IP address identifies a specific device on a network?
• first two octets
• third and fourth octets
• network portion

• host portion
• only the fourth octet

Q.4. Given a host with the IP address 172.32.65.13 and a default subnet mask, to which network does the host belong?
• 172.32.65.0
• 172.32.65.32

• 172.32.0.0
• 172.32.32.0

Q.5. Which default subnet mask provides the most host bits?

• 255.0.0.0
• 255.255.0.0
• 255.255.255.0
• 255.255.255.252

Q.6. How many bits are available for Class B host IP addresses using a default subnet mask?
• 4
• 8

• 16
• 24

Q.7. How many usable hosts are available given a Class C IP address with the default subnet mask?

• 254
• 255
• 256
• 510
• 511
• 512

Q.8. Assuming a default mask, which portion of the IP address 175.124.35.4 represents the host?
• 175.124
• 35.4
• .4
• 124.35.4
• 175.124.35

Q.9. Which of the following are private IP addresses? (Choose three.)

• 224.6.6.6

Q.10. What destination IP address is used in a unicast packet?
• a specific host
• a group of hosts
• the default gateway
• the network broadcast address

Q.11. What is the destination MAC
