If the standard port number for the Telnet service is 23, a host whose IPv4 address is 10.43.3.87 has a socket address for Telnet of ____.

10.43.3.87:23

Both BOOTP and DHCP are protocols that belong to this layer of the OSI model.

Application

DNS is a reliable way of locating a host whose IP address doesn't change. But when locating hosts whose IP addresses change, you should use

DDNS

In most cases, BOOTP has been surpassed by the more sophisticated IP addressing utility, ____.

DHCP

Which of the following is NOT an advantage of DHCP over BOOTP?

DHCP does not require the network administrator to install and configure the service on a server.

DNS

F:10::2:0:0:1A3B

This Application layer protocol allows you to send and receive files via TCP/IP.

FTP

BOOTP is a more sophisticated IP addressing utility than DHCP.

False

FTP is used to synchronize the computer clocks on a network.

False

Google is an example of a top-level domain.

False

IPv4 has 32 bits, while IPv6 has 64 bits.

False

IPv4 is gradually replacing IPv6.

False

If your network does not need or use APIPA, it must be uninstalled to avoid conflicts

False

Larger organizations that pay for static IP addresses are required to use DDNS instead of DNS.

False

Most large organizations maintain three name servers.

False

TFTP is more secure than FTP.

False

The following is a valid IPv6 address: D:7:0:0:0:0:0:0:CC15

False

The following is a valid IPv6 address: D:7:0:0:EE:0:CC15

False

With DHCP, a device is assigned a static IP address.

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.

True

____ is more efficient than TCP for carrying messages that fit within one data packet

UDP

Ports ranging from 0 to 1023; assigned to processes that only the operating system or an administrator of the system can access.

Well Known Ports

___________ ports range from 0 to 1023 and are assigned to processes that only the operating system or administrator can use.

Well-known

A(n) ____ address represents any one interface from a group of interfaces, any one of which can accept a transmission.

anycast

___________ addresses are usually assigned to routers.

anycast

BOOTP and DHCP are two methods of

automatically assigning IP addresses

In the domain name www.chattahoocheetech.edu, the second-level domain is

chattahoocheetech

In the domain name www.google.com, ____ is the top-level domain (TLD).

com

TCP/IP addressing involves long and complicated numbers. That's why an Internet naming system was developed. A host's name is known as its

domain name

The most common way of expressing IP addresses.

dotted decimal notation

A ___________ IP address is one that is assigned upon request and is changeable.

dynamic

In the domain name www.chattahoocheetech.edu, the top-level domain is

edu

The local host name plus its domain name.

fully qualified host name

The ASCII text file called HOSTS.TXT that associates host names with IP addresses.

host file

Transmitting the same data to many different devices simultaneously, as in point-to-multipoint communications requires a ___________ address.

multicast

This component of the DNS service contains databases of associated names and IP addresses and provides this information upon request.

name server

The database of Internet IP addresses and their associated names.

namespace

This component of the DNS service is an abstract database of Internet IP addresses and their associated names. It is the term we use when we want to describe how DNS information is shared around the world.

namespace

This component of the DNS service will initiate finding the IP address of the domain name requested. However, if you have already visited the website, your computer may remember the IP address.

resolver

Any hosts on the Internet that need to look up domain name information.

resolvers

When you combine a process's port number with its host machine IP address, you get the process's ______.

socket

An IP address that is assigned manually and does not change automatically is known as a __________ IP address.

static

The purpose of APIPA is

to furnish an IP address if there is no DHCP sever available

Transmitting to a single device requires a ___________ address.

unicast
