Module 12

For two hosts that are on the same network, which of the following statements are true? (Choose three.)

• Both hosts will have the same IP address.

• Both hosts will have different IP addresses.

• Both hosts will have different default gateway addresses.

• Both hosts will have the same default gateway address.

• Both hosts will have different MAC addresses.

For two hosts, each on a different network, which of the following statements are true? (Choose three.)

• Both hosts will have the same MAC address.

• Both hosts will have the same IP address.

• Both hosts will have different MAC addresses.

• Both hosts will have different default gateway addresses.

• Both hosts will have different IP addresses.

A computer has to send a packet to a destination host in the same LAN. How will the packet be sent?

• The packet will be sent to the default gateway first, and then, depending on the response from the gateway, it may be sent to the destination host.

• The packet will be sent directly to the destination host.

• The packet will first be sent to the default gateway, and then from the default gateway it will be sent directly to the destination host.

• The packet will be sent only to the default gateway.

Typically, which network device would be used to perform NAT for a corporate environment?

• DHCP server

• host device

• router

• server

• switch

Which characteristic describes the default gateway of a host computer?

• the logical address of the router interface on the same network as the host computer

• the physical address of the switch interface connected to the host computer

• the physical address of the router interface on the same network as the host computer

• the logical address assigned to the switch interface connected to the router

What is the purpose of configuring a default gateway address on a host?

• to provide a permanent address to a computer

• to identify the network to which a computer is connected

• to identify the logical address of a networked computer and uniquely identify it to the rest of the network

• to identify the device that allows local network computers to communicate with devices on other networks

If the default gateway is configured incorrectly on a host, what is the impact on communications?

• The host is unable to communicate on the local network.

• The host is unable to communicate with hosts on remote networks.

• The host is unable to communicate with hosts on both the local and remote networks.

• The host cannot get an IP address from the DHCP server.

Which three IPv4 network addresses are private IP addresses? (Choose three.)

• 10.0.0.0

• 172.32.0.0

• 192.157.0.0

• 172.16.0.0

• 192.168.0.0

What is the purpose of NAT?

• allowing hosts configured with registered public IP addresses to access the internet

• translating private IP addresses to a public registered IP address

• routing private IP addresses over the public internet

• assigning a private IP address to a host for internet access

What is the primary advantage of using NAT?

• allows a large group of users to share one or more public IP addresses

• allows a large group of users to share the same private IP address within a LAN

• allows static mapping of public inside addresses to private outside addresses

• allows dynamic mapping of registered inside addresses to private outside addresses
