(NCP) stands for what. 157

Answer 4

Network Control Protocol (NCP)

Question 5

The DoD model is basically a condensed version of the OSI model—it’s composed of four, instead of seven, layers: p158

Answer 5

Process/Application layer
Host-to-Host layer
Internet layer
Network Access layer

Question 6

When the different protocols in the IP stack are discussed, the layers of the OSI and DoD models are what. p158

Answer 6

interchangeable

Question 7

To integrate the various activities and duties spanning the focus of the OSI’s corresponding top three layers. p158

Answer 7

Process/Application layer

Question 8

Parallels the functions of the OSI’s Transport layer, defining protocols for setting up the level of transmission service for applications. p159

Answer 8

Host-to-Host layer

Question 9

Corresponds to the OSI’s Network layer, designating the protocols relating to the logical transmission of packets over the entire network. p159

Answer 9

Internet layer

Question 10

Monitors the data exchange between the host and the network.

Answer 10

Network Access layer

Question 11

What is Telnet? p160

Answer 11

Telnet is the chameleon of protocols—its specialty is terminal emulation. It allows a user on a remote client machine, called the Telnet client, to access the resources of another machine, the Telnet server.

Question 12

Is the protocol that actually lets you transfer files across an IP network, and it can accomplish this between any two machines using it. p160

Answer 12

File Transfer Protocol (FTP)

Question 13

Is used when you need to transfer files over an encrypted connection. It uses an SSH session more on this later which encrypts the connection. P161

Answer 13

Secure File Transfer Protocol (SFTP)

Question 14

Is the stripped-down, stock version of FTP, but it’s the protocol of choice if you know exactly what you want and where to find it. It doesn’t give you the abundance of functions that FTP does, though. p161

Answer 14

Trivial File Transfer Protocol (TFTP)

Question 15

Once a message has been sent to a destination, the message is spooled to a device—usually a disk. The server software at the destination posts a vigil, regularly checking the queue for messages. p162

Answer 15

Simple Mail Transfer Protocol (SMTP)

Question 16

Basically, how this protocol works is when a client device connects to a POP3 server, messages addressed to that client are released for downloading. p162

Answer 16

Post Office Protocol (POP)

Question 17

makes it so you get control over how you download your mail, with it, you also gain some much-needed security. It lets you peek at the message header or download just a part of a message.p162

Answer 17

Internet Message Access Protocol, Version 4 (IMAP4)

Question 18

Is a proprietary protocol developed by Microsoft. It allows you to connect to another computer and run programs. p162

Answer 18

Remote Desktop Protocol (RDP)

Question 19

Are cryptographic protocols that come in really handy for enabling secure online data-transfer activities like browsing the Web, instant messaging, internet faxing, and so on. p163

Answer 19

Transport Layer Security (TLS)

Question 20

Is a hugely popular signaling protocol used to construct and deconstruct multimedia communication sessions for many things like voice and video calls, video conferencing, streaming multimedia distribution, instant messaging, presence information, and online games over the Internet. p163

Answer 20

SIP (VoIP)

Question 21

Describes a packet-formatting standard for delivering audio and video over the Internet. Although initially designed as a multicast protocol, it’s now used for unicast applications too. p163

Answer 21

RTP (VoIP)

Question 22

Collects and manipulates valuable network information. It gathers data by polling the devices on the network from a management station at fixed or random intervals, requiring them to disclose certain information. p163

Answer 22

Simple Network Management Protocol (SNMP)

Question 23

When all is well, SNMP receives something called a what? p163

Answer 23

baseline

Question 24

These network watchdogs are called _____ and when aberrations occur, agents send an alert called a _____ to the management station. p163

Answer 24

agents

trap

Question 25

sets up a secure Telnet session over a standard TCP/IP connection and is employed for doing things like logging into other systems, running programs on remote systems, and moving files from one system to another.p164

Answer 25

Secure Shell (SSH)

Question 26

Allowed a host to retrieve a large amount of data at once.p163

Answer 26

GETBULK

Question 27

It’s used to manage communications between web browsers and web servers and opens the right resource when you click a link, wherever that resource may actually reside.p164

Answer 27

Hypertext Transfer Protocol (HTTP)

Question 28

t’s a secure version of HTTP that arms you with a whole bunch of security tools for keeping transactions between a web browser and a server secure. p164

Answer 28

Hypertext Transfer Protocol Secure (HTTPS)

Question 29

Both _______and ______ is used to encrypt packets over your intranet and the internet. p164

Answer 29

SSH (port 22)

HTTPS (port 443)

Question 30

Works in conjunction with other synchronization utilities to ensure all computers on a given network agree on the time. p164

Answer 30

Network Time Protocol (NTP)

Question 31

Transferring data, usernames and passwords get sent right along with the file request in the clear for all to see with no encryption. p165

Answer 31

Secure Copy Protocol (SCP)

Question 32

This protocol standardizes how you access directories, and its first and second inceptions are described in RFCs 1487 and 1777, respectively. p165

Answer 32

Lightweight Directory Access Protocol (LDAP)

Question 33

What is Internet Group Management Protocol (IGMP) p165

Answer 33

is the TCP/IP protocol used for managing IP multicast sessions. It accomplishes this by sending out unique IGMP messages over the network to reveal the multicast-group landscape and to find out which hosts belong to which multicast group.
