Karl is a network administrator. He's been asked to implement dynamic IP addressing the company's newly installed network, which has two subnets in one Active Directory domain with servers running Windows Server 2003. After Karl installs and configures the DHCP server in SubnetA, client computers in SubnetA are able to obtain DHCP leases and the proper TCP/IP configuration. What is the most likely cause of the problem?
- A.
The DHCP server is not authorized in SubnetB
- B.
The DHCP scope for SubnetB is not active
- C.
The DHCP server service is stopped
- D.
A DHCP Relay Agent is not installed in SubnetB
Correct Answer
D. A DHCP Relay Agent is not installed in SubnetBExplanation
Answer D is correct. A DHCP Relay Agent (or a BOOTP-compatible router) must be installed in SubnetB to route DHCP broadcast messages between networks.Rate this question:

Frank's computer is configured to use DHCP. When Frank logs on, he notices he can't connect to the network. The computer has no IP address according to ipconfig. Which of the following is most likely true?
- A.
No DHCP server is on the network
- B.
The computer is using Automatic Private IP Addressing
- C.
The network cable to the computer is disconnected
- D.
The computer is using dynamic IP addressing
Correct Answer
C. The network cable to the computer is disconnectedExplanation
Answer C is correct. APIPA requires an active network connection (in most cases) for automatic configuration to work properly. If the network cable to a computer is disconnected or improperly connected, the computer may no be assigned an IP address. When you type ipconfig /all at a command prompt, you may see an error stating "Media Disconnected."Rate this question:

The company has two subnets in one Active Directory domain with servers running Windows Server 2003. On the DHCP server, Scope1 provides dynamic addressing for SubnetA, and Scope2 provides dynamic addressing for SubnetB. Client in SubnetA are able to obtain DHCP leases, but are unable to access resources in SubnetB. What is the best way to solve the problem?
- A.
Reconfigure the network's DHCP Relay agent
- B.
Activate Scope1
- C.
Activate Scope1 and Scope2
- D.
Configure the default gateway on client computers
- E.
Configure the TCP/IP router option for Scope1
Correct Answer
E. Configure the TCP/IP router option for Scope1Explanation
Answer E is correct. If client computers have an improperly configured gateway, they are not able to access resources outside of their local subnet. The best way to solve this problem is to configure the TCP/IP router option (option 003) for Scope1. Although you could configure a default gateway on client computers, this is not the best way to solve the problem, so Answer D is incorrect.Rate this question:

Which of the following is most likely tru if a computer with an IP address of 169.254.201.10?
- A.
No DHCP server is on the network
- B.
A DHCP server is assigning the computer's IP address
- C.
The computer has a static IP address
- D.
The network cable is disconnected
Correct Answer
A. No DHCP server is on the networkExplanation
Answer A is correct. When DHCP is configured but not available, or the client lease is expired and cannot be renewed, clients use Automatic Private IP Addressing. Whith APIPA, clients assign themselves an IP address in the range of 169.254.0.1-169.254.255.254, with a subnet mask of 255.255.0.0.Rate this question:

April is a network administrator for an Acitve Directory domain with servers running Windows Server 2003. April recently installed a second DHCP server on the local subnet. When testing the server, she notices the DHCP Server service is being shut down and she can't get the service to stay running. What is the most likely cause of this problem?
- A.
The DHCP server service is improperly installed
- B.
The DHCP server does not have an active scope
- C.
The active scope has invalid TCP/IP options
- D.
The DHCP server has not be authorized in Active Directory
Correct Answer
D. The DHCP server has not be authorized in Active DirectoryExplanation
Answer D is correct. With Windows 2000 and later, a workgroup or stand-alone DHCP server configured on the same subnet as a domain's authorized DHCP server is considered to be a rogue server. As part of a network protection process, the rogue server automatically stops its DHCP Server service and stops leasing IP addresses to clients. To resolve this issue, you must authorize the DHCP server in Active Directory.Rate this question:

Carlos is responsible for the managing DHCP. The organization has a single Class C subnet with 254 available IP addresses. the network ID is 192.168.10.0. Carlos wants a single scope to cover all 254 IP addresses. However, he needs to ensure 14 of the IP addresses aren't used by DHCP clients and that 8 of the IP addresses are always assigned to the same member servers. Which of the following should be done to configure the scope? (Choose Two)
- A.
Create the scope for the IP address range 192.168.10.0.-192.168.10.255
- B.
Create the scope for the IP address range 192.168.10.1-192.168.10.254
- C.
Create an exclusion range for the 8 member servers and reserve the other 14 IP addresses
- D.
Create an exclusion range for the 14 member servers and reserve the other 8 IP addresses
Correct Answer(s)
B. Create the scope for the IP address range 192.168.10.1-192.168.10.254
D. Create an exclusion range for the 14 member servers and reserve the other 8 IP addressesExplanation
Answer B and D are correct. The assignable IP address for the network is 192.168.10.1 to 192.168.10.254. To ensure a client computer gets the same IP address, create a reservation on a lease. To ensure an IP address is not used, create an exclusion.Rate this question:

You want to configure multiple standard scopes so that they can be easily activated or deactivated. What should you do?
- A.
Create a multicast scope and add the standard scopes to it
- B.
Create a superscope and add the standard scopes to it
- C.
Delete all the scopes except one
- D.
Configure server options instead of scope options
Correct Answer
B. Create a superscope and add the standard scopes to itExplanation
Answer B is correct. A superscope is a container for scopes that allows you to more easily work with multiple scopes. After you create a superscope, you can add to it the scopes you want to manage as a group.Rate this question:

The network has three subnets: SubnetA, SubnetB, and SubnetC. The DHCP server on SubnetA is configured with one scope for each subnet. The network administrator configured the TCP/IP settings using Server options, which works fine for Clients on SubnetA, but not for clients on SubnetB and SubnetC. What should be done to resolve this problem?
- A.
Set scope options for the SubnetB and SubnetC scopes as appropriate to override server options
- B.
Remove the server options and set only scope options for the SubnetA, SubnetB, and SubnetC scopes
- C.
Remove the server options and set only class options
- D.
Set predefined options as appropriate to override server options
Correct Answer
A. Set scope options for the SubnetB and SubnetC scopes as appropriate to override server optionsExplanation
Answer A is correct. The clients on SubnetB and SubnetC are likely getting the wrong TCP/IP router option. By setting the correct TCP/IP router option as a scope option, you can override the server options for the settings.Rate this question:

- B.
The client queries its primary DNS server
- C.

Which of the following correctly describes recursive and iterative queries? (Choose Two)
- A.
A DNS server must respond directly to a recursive query or return an error, and queries other DNS servers on behalf of the client if unable to resolve a query from its cache/zone database
- B.
A DNS server must resolve an iterative query from its local cache or return an error, and is unable to contact other DNS servers on behalf of the client
- C.
A DNS sever must resolve a recursive query from its cache if possible, and if not, must refer the client to another DNS server
- D.
A DNS server must resolve an iteractive query from its local cache/zone database or refer the client to another DNS server
Correct Answer(s)
A. A DNS server must respond directly to a recursive query or return an error, and queries other DNS servers on behalf of the client if unable to resolve a query from its cache/zone database
D. A DNS server must resolve an iteractive query from its local cache/zone database or refer the client to another DNS serverExplanation
Answer A and D are correct. With a recursive query, the DNS server must respond directly to a recursive query or return an error, and queries other DNS servers on behalf of the client if unable to resolve a query. With an iterative query, a DNS server attempts to resolve the query from its records or from its cache, and if it is unable to resolve the query, the server can refer the client to another DNS server.Rate this question:
