Which protocol is used to automatically provide TCP/IP addressing configuration to a network host?

• NAT

• ARP

• DHCP

• CSMA/CD

The effect of subnetting on a network is to

• Slow down the network

• Increase subnet size to accommodate more hosts

• Increase network performance by creating smaller broadcast domains

• The network becomes more difficult to manage

The main difference between IPv4 and IPv6 is

• IPv4 has 4 bytes while IPv4 has 128 bytes

• IPv4 has 32 bits while IPv6 has 32 bytes

• IPv4 has 32 bits while IPv6 has 128 bits

• IPv4 has 4 bytes while IPv6 has 6 bytes

How do you know if 2 PC's are on the same network?

• They have the same host ID

• They have the same net ID

• They have the same MAC address

• They have the same subnet mask

In ARP request, the destination MAC address is?

• A broadcast IP address

• A class C IP address

• A multicast IP address

• A broadcast MAC address

What is the function of a default gateway in a network?

• To enable communication on the same local area network

• To connect a PC with the server to improve communication

• To connect PC's together

• To enable communication with a different network

The command ipconfig /all is used as

• A method to reduce the attenuation of a signal

• An IP address used for testing purposes

• A network utility used to detect intrusion

• A utility that is used to display the network configuration of a PC

What is the main function of DNS

• Translates a private IP address to a public IP address

• Translates host names to IP addresses

• Find the best route to the destination
