CIW NTA L3 Test Review

Which of the following is TRUE of Bluetooth?

• There are more than 15 Bluetooth classifications, each with different signal strength and range.

• Bluetooth is a wired protocol used to exchange data over relatively long distances.

• Bluetooth likely will replace wireless LANs because its range is greater than that of a LAN.

• Bluetooth is not designed to replace wireless LAN technologies because its range is too limited.

What command provides information about round-trip propagation time between each router and the source system?

• The route command

• The tracert command

• The netstat command

• The ping command

If you experience a loss of email service or can no longer access the Web, what command can your network administrator use to locate the cause of the failure?

• The route command

• The tracert command

• The netstat command

• The ping command

Why would you ping an IP address? Mark only one oval.

• To ensure that DNS is working properly

• To ensure that you have connectivity

• To determine the path between a source and destination system

• To display the physical (MAC) address of the computer with which you are communicating

Which choice correctly describes the basic configuration parameters required for WAN communication? Mark only one oval.

• An IP address

• An IP address and a subnet mask

• An IP address and a default gateway

• An IP address, a mask, a default gateway, and a DHCP client

Which entity is a private, non-governmental organization that performs tasks such as Internet address space allocation? Mark only one oval.

• Internet Engineering Task Force (IETF)

• Internet Assigned Numbers Authority (IANA)

• Institute of Electrical and Electronics Engineers (IEEE)

• Internet Corporation for Assigned Names and Numbers (ICANN)

Most IP-enabled systems are configured with a default gateway, which is an IP address that:

• begins with 127.

• specifies a routing device.

• requires the use of Network Address Translation (NAT).

• allows a client and server on the same host to communicate with each other.

What is the function of the hosts file?

• It assigns private IP addresses to clients.

• It maps DNS host names to IP addresses.

• It enables IPv6 interfaces to communicate with each other if they are linked.

• It assigns the IP address and subnet mask to your system.

For one computer to communicate with another computer over a TCP/IP network, it must know the other computer's:

• LAN Address

• street address

• MAC address

• Internet address

Which protocol is found at the Internet layer of the Internet architecture and is responsible for translating Internet addresses to physical addresses?

• Domain Name System (DNS)

• Address Resolution Protocol (ARP)

• Dynamic Host Configuration Protocol (DHCP)

• Reverse Address Resolution Protocol (RARP)
