False

In IPv6, each address contains a(n) ____, or a variable-length field at the beginning of the address that indicates what type of address it is.

Format Prefix

This Application layer protocol allows you to distribute messages to a wide group of users at once.

NNTP

This Application layer protocol is used to synchronize the computer clocks on a network.

NTP

____ is a simple Application layer protocol used to synchronize the clocks of computers on a network.

NTP

This utility is used to verify that TCP/IP is installed, configured correctly, and communicating with the network.

PING

____ is a utility that can verify that TCP/IP is installed, bound to the NIC, configured correctly, and communicating with the network.

PING

___________ ports range from 1024 to 49151 and are accessible to network users and processes with no special privileges.

Registered

Ports ranging from 1024 to 49151; accessible to network users and processes that do not have special administrative privileges.

Registered Ports

Which of the following is NOT an Application layer protocol?

STP

This Application layer protocol is used to log on to remote hosts using the TCP/IP protocol suite.

Telnet

____ is a terminal emulation protocol used to log on to remote hosts using the TCP/IP protocol suite.

Telnet

A DHCP lease can expire automatically, or it can be terminated manually by either the server or the client.

True

APIPA is suitable for use in small networks with no DHCP servers.

True

Every network node must have a unique IP address.

True

IPv6 addresses are usually displayed as hexadecimal numbers separated by colons.

True

IPv6 offers more security and many more IP addresses than IPv4.

True

If a name server doesn't contain a requested domain name and IP address, it passes the query on to a higher-authority name server.

True

Old networks might use text files called host files to associate host names with their IP addresses.

True

The DHCP server and the client communicate with each other to determine the client's lease of an IP address and its duration.

True

The following is a valid IPv6 address: 1B:7:0:0:0:0:CC15:BB28

True

The use of port numbers simplifies TCP/IP communications and ensures that data is transmitted to the correct application.

True

There are 13 main DNS computers known as root servers.

True

Top-level domains can include country abbreviations such as RUS or UK in addition to common ones such as COM and ORG.

True

Unicast is more common than multicast or anycast, and involves the interface of two individual devices.

True

Using Telnet, you can use the keystrokes on your computer act like keystrokes on a remotely connected computer.

True

When you want to find a new website, your http client software initiates the resolver to find the IP address.

True

You can "Ping" either an IP address or a host name.
