Back 9

In the DHCP console the scope will have an icon showing a red down arrow.

Front 10

What is the purpose of an exclusion range?

Configuration information regarding DNS domain name (15), DNS servers (06), WINS servers (44), routers (03), (default gateways) and more.

Front 15

Why should DHCP options be configured ?

Back 15

When should a DHCP lease duration be reduced ?

Back 17

When a limited # of IP addresses is available.

Front 18

When should a DHCP lease duration be increased ?

Back 18

What an ample # of IP addresses are available.

Front 19

How can a client be configured to use a particular static IP address when it is unable to obtain an IP address from DCHP dynamically ?

Back 19

Use the Alternate Configuration tab on the TCP/IP properties.

Front 20

How is the DHCP database backed up ?

Back 20

Automatically or Manually through the DHCP console or NTBackup

Front 21

Back 21

A backup created manually through the DHCP console or NTBackup

Front 22

What is the best means of restoring a DHCP database ?

Back 22

Use the DHCP console.

Front 23

What is the command line text necessary to stop the DHCP service? Start the service?

Back 23

Net stop dhcpserver, net start dhcpserver

Front 24

What steps should be taken to move a DHCP databse from one server to another ?

Back 24

1.Backup the DHCP database.
2.Stop the DHCP service on the old server.
3.Copy the backup to new server.
4.Restore the DHCP database to new server.
5.Start the DHCP service.
6.Ensure server is authorized and scopes are activated.

Front 25

What does APIPA stand for ?

Back 25

Automatic Private IP Addressing.

Front 26

What is the purpose of APIPA ?

Back 26

Allow client systems to self assign an IP address if one cannont be obtained from DHCP server.

Front 27

When configuring a new DHCP database what feature can be enabled to ensure that duplicate IP addresses are not delivered ?

Back 27

Conflict Detection.

Front 28

What does DORA stand for ?

Back 28

Discover
Offer
Request
Acknowledgement

Front 29

During DORA, which steps does the client send its MAC address ?

Back 29

Discover

Front 30

What does a DHCP server return when an address cannot be given ?

Back 30

NACK or Negative Acknowledgement.

Front 31

What are some causes for excessive NACKs ?

Back 31

Server not authorized, scope not activated or a rogue DHCP server exists.

Front 32

What is the purpose of a DHCP Relay Agent ?

Back 32

Allow clients on remote networks to obtain an IP address from a DHCP server that is separated by non-RFC1542 compliant routers.

Front 33

Routers that do not support DHCP traffic are said not to pass what kind of traffic ?

Back 33

BOOTP

Front 34

How is a DHCP Relay Agent configured ?

Back 34

The DHCP Relay Agent is a service available when the Routing and Remote Access service is enabled.

Front 35

Can A DHCP Relay Agent be configured on a Windows XP Professional system ?

Back 35

No, it must be a server other than the DHCP server itself.

Front 36

Can a DHCP Relay Agent be configured on a non-Windows router ?

Back 36

Yes. Cisco routers, for example, support the ability to be a DHCP Relay Agent.

Front 37

For segments that contain DHCP server and a DHCP Relay Agent, what needs to be done to ensure that the DHCP server is given a chance to respond before the Relay Agent picks up the request ?

Back 37

The Relay Agent Boot Threshold needs to be configured.

Front 38

What is the default Relay Agent Boot Threshold ?

Back 38

4 Seconds.

Front 39

How can the integrity of the DHCP database be verified ?

Back 39

Reconcile all scopes.

Front 40

How should the DHCP-DNS intergration be configured to force DHCP to update all client records, remove lease expired records, and update on behalf of down-level (non-dynamic DNS capable) clients?
