Network Fundamentals 98-366 Lesson 6

Front 1

Acknowledge

Back 1

When the DHCP server sends a final unicast to the client that includes the IP information the client will use.

Front 2

authentication header (AH)

Back 2

An IPSec component that provides connectionless integrity and the authentication of data. It also provides protection versus replay attacks.

Front 3

Discovery

Back 3

A step in DORA when a client computer broadcasts out to the network in order to find a DHCP server.

Front 4

domain name system (DNS)

Back 4

A worldwide service that resolves host names to IP addresses.

Front 5

DORA

Back 5

Short for Discovery, Offering, Request and Acknowledge, this is the four-step process used with DHCP.

Front 6

Dynamic Host Configuration Protocol (DHCP)

Back 6

A protocol that allows properly configured client computers to obtain IP addresses automatically from a DHCP server.

Front 7

encapsulating security payload (ESP)

Back 7

An IPSec component that provides the same services as AH but also provides confidentiality when sending data.

Front 8

IP forwarding

Back 8

LAN routing that bridges the gap between the two network adapters even if they are on two different IP networks.

Front 9

Internet Protocol Security (IPSec)

Back 9

A protocol within the TCP/IP suite that encrypts and authenticates IP packets.

Front 10

Offering

Back 10

When the DHCP server sends out a unicast "offering" of an IP address to the client computer.

Front 11

Remote Access Service (RAS)

Back 11

A grouping of different hardware and software platforms to allow remote access to another computer or network device.

Front 12

Remote Desktop Protocol (RDP)

Back 12

The protocol used when you use the Remote Desktop Connections program to connect to a computer.

Front 13

Remote Desktop Services

Back 13

A type of thin-client terminal server computing. It allows client computers to access and use applications loaded on the server, as well as to connect to and take control of a server. It was previously known as Terminal Services.

Front 14

Request

Back 14

In DHCP, when the client broadcasts to all servers that it has accepted the offer.

Front 15

Routing and Remote Access Service (RRAS)

Back 15

A network service in Windows Server 2008, Windows Server 2003, and Windows Server 2000. It permits an administrator to configure dial-up remote access servers, VPN servers, and IP routing, as well as NAT.

Front 16

security association (SA)

Back 16

The IPSec component that generates the encryption and authentication keys that are used by IPsec.

Front 17

Terminal Services

Back 17

A type of thin-client terminal server computing. It allows client computers to access and use applications loaded on the server, as well as to connect to and take control of a server.

Front 18

Windows Internet Name Service (WINS)

Back 18

A service that resolves NetBIOS names to IP addresses.

Front 19

Ports 67 & 68

Back 19

Proseware, Inc., wants you to scan servers for DHCP activity. Which ports should you be looking for?

Front 20

The scope was not activated

Back 20

A coworker asks for your help in analyzing a problem with a DHCP server. The server's scope has been created and the Ip range appears to be valid, yet no clients are obtaining Ip addresses. What could be the reason for this?

Front 21

Terminal Services Is Running

Back 21

You have just scanned the ports of your server and see that port 3389 is open. What can you deduce from this?

Front 22

Request (DORA)

Back 22

Your Windows client failed to broadcast to all servers that it has accepted an IP address offer. What step is this in the four-step DORA process?

Front 23

Request & Acknowledge

Back 23

When renewing a DHCP assigned IP address, usually the __________ steps of the DORA process are involved.

Front 24

It cannot communicate with a DHCP server

Back 24

You have a computer with an address of 196.254.32.23 and a subnet mask of 255.255.0.0, yet you cannot connect to your local file servers. What is most likely the problem?

Front 25

Routing and Remote Access Service (RRAS)

Back 25

You have been asked by a client to install a VPN server. Which of the following services shouldl be chosen in order to accomplish this?

Front 26

Six

Back 26

By default, wired DHCP leases last for ________ days.

Front 27

Security Association (SA)

Back 27

Security Association (SA) Which protocol generates encryption and authentication keys that are used by IPsec?
