Practice Questions

Question 1

You recently installed the DHCP Server service on one of your Windows 2000 member servers in the domain. You notice that the DHCP service is constantly being shut down. What is causing the problem to occur?

  • A. The DHCP server has not been configured with a scope.

  • B. The scope on the DHCP server has not been activated.

  • C. The DHCP server has not been authorized within Active Directory.

  • D. There is a DHCP server on the network with a duplicate scope.

A1:

Answer C is correct. If a DHCP server has not been authorized within Active Directory, it is considered to be a rogue server and the service will continue to shut down until it is authorized. Answers A, B, and D are incorrect because none of these problems would cause the DHCP service to shut down.

Question 2

You recently upgraded all workstations from Windows 98 to Windows 2000 Professional. Your network has a DNS server, a WINS server, and a Windows NT 4.0 DHCP server. The reason for upgrading the clients to Windows 2000 Professional is to take advantage of dynamic updates. After you upgrade the clients to Windows 2000, you notice the DNS records are not being updated. What must you do to take advantage of dynamic updates?

  • A. Within the DHCP Manager, configure the DHCP server to upgrade the records for clients.

  • B. The DNS server must be configured to accept updates from the Windows 2000 Professional clients.

  • C. The WINS server must be removed from the network.

  • D. The DHCP server must be upgraded to Windows 2000 Server.

A2:

Answer D is correct. Windows NT 4.0 DHCP does not support dynamic DNS. The existing DHCP server must be upgraded to Windows 2000 Server. Therefore, answers A and B are incorrect. Answer C is incorrect because removing the WINS server will not have any impact on whether dynamic updates can occur.

Question 3

You are having problems with your DHCP server—it does not seem to be functioning correctly. You'd like to begin troubleshooting this by logging all DHCP activity to the System log. How can you enable this logging option?

  • A. Open the Properties dialog box for the DHCP server and select the Enable Audit Logging check box on the Advanced tab.

  • B. Open the Properties dialog box for the DHCP server and select the Automatically Update Statistics check box on the Advanced tab.

  • C. Open the Properties dialog box for the DHCP server and select the Enable Audit Logging check box on the General tab.

  • D. Nothing needs to be done. The DHCP server logs all activity to the System log by default.

A3:

Answer C is correct. To have DHCP activity logged to the System log, open the Properties dialog box for the DHCP server and make sure the General tab is active. Select the Enable DHCP Logging check box. Answer A is incorrect because logging is configured on the General tab. Answer B is incorrect because selecting the option to Automatically Update Statistics does not enable logging. Answer D is incorrect because logging is not enabled by default.

Question 4

Your network consists of multiple subnets connected by routers. You have finished installing a Windows 2000 DHCP server. You create the necessary scopes and configure the 003 router option to assign all clients the IP address of their local router. All clients successfully lease an IP address. However, you soon discover that users on Subnet A are the only ones capable of communicating outside their local subnet. What could be causing the problem?

  • A. All the scopes have not yet been activated.

  • B. The DHCP option is configured at the server level.

  • C. The DHCP server has not yet been authorized.

  • D. The 003 router option must first be activated.

A4:

Answer B is correct. Each subnet will have its own gateway so the 003 router option should be configured at the scope level instead of the server level. Answers A and C are incorrect because all clients are successfully leasing IP addresses. Answer D is incorrect because DHCP options do not have to be activated.

Question 5

Your company placed you in charge of configuring a Windows 2000 DHCP server. The network was recently upgraded to Windows 2000 and Active Directory. The network consists of three domains. You are a member of the Administrator group in each of the domains. You install the DHCP server and create the necessary scopes. When you attempt to authorize the DHCP server, you receive an “access denied” message. What is causing the problem to occur?

  • A. You are not a member of the Administrators group in the forest root domain.

  • B. Active Directory is unavailable.

  • C. You are not logged on as the local Administrator on the DHCP server.

  • D. You are not a member of the Enterprise Admins group.

A5:

Answer D is correct. To authorize a DHCP server, the user account you are logged on with must be a member of the Enterprise Admins group. Therefore, answers A and C are incorrect. Answer B is incorrect because if Active Directory was unavailable, you would receive a different error message altogether.

Question 6

You are a junior network administrator. One of your tasks is to maintain a newly installed DHCP server. The scopes have not yet been created. The senior administrator documents all the required scopes and asks you to create them on the server. You notice several DHCP options are to be configured, but it is not specified what type of scope options to configure. You are trying to recall how scope options are applied. Which of the following correctly lists the order in which they are applied to clients?

  • A. Server, Scope, Class, Client

  • B. Server, Class, Scope, Client

  • C. Server, Scope, Client, Class

  • D. Scope, Server, Client, Class

A6:

Answer A is correct. The correct order in which DHCP options are applied is server, scope, class, and then client. Therefore, answers B, C, and D are incorrect.

Question 7

Bayside Consulting firm currently consists of 400 workstations. One hundred clients are running Windows 95 and the remaining clients are running Windows 2000 Professional. You use a Windows 2000 DHCP server to automate the task of assigning IP addresses. All clients on the network are successfully receiving IP addresses from the server. When you check the DNS zone file, you notice that only the Windows 2000 Professional clients have records. How can you most easily resolve the problem?

  • A. Upgrade the Windows 95 clients to Windows 2000 Professional.

  • B. Configure the properties of the DHCP server to always update DNS.

  • C. Configure the properties of the DHCP server to enable updates for DNS clients that do not support dynamic updates.

  • D. Configure the Windows 95 workstations to update their own records.

A7:

Answer C is correct. By selecting the option to enable updates for DNS clients that do not support dynamic updates, the DHCP server can update the address and pointer records on behalf of the Windows 95 clients. Therefore, answer B is incorrect. Answer A is incorrect because it would not provide the easiest solution. Answer D is incorrect because Windows 95 clients cannot interact directly with a DNS server regardless of their configuration.

Question 8

Your organization recently increased the number of workstations on the network. To simplify the process of assigning IP addresses, you are implementing DHCP. The budget allows for the purchase of two new servers that will both run DHCP. Two subnets exist, and a DHCP server will be placed in each one. How can you ensure that clients can still lease IP addresses in the event that one of the DHCP servers is unavailable?

  • A. Configure replication to occur between the two DHCP servers.

  • B. Nothing needs to be configured, because DHCP servers on the same network share scope information.

  • C. Configure each server with a range of IP addresses for both subnets.

  • D. Configure all clients with the IP address of both DHCP servers.

A8:

Answer C is correct. To provide fault tolerance, each DHCP server should be configured with a range of IP addresses for both subnets. Each DHCP server should have a scope with 80% of the IP addresses for its local subnet and a scope with 20% of the IP addresses in the remote subnet. This provides fault tolerance without the chance of duplicate IP addresses. Answers A and B are incorrect because DHCP servers do not share scope information. Answer D is incorrect because clients are not configured with the IP addresses of a DHCP server. A DHCP server is located using a broadcast.

Question 9

You install the DHCP Server service on a Windows 2000 member server. The DHCP server is authorized in Active Directory and all the required scopes are created. Clients on the network cannot lease IP addresses from the server. What is causing the problem to occur?

  • A. The scope has not been authorized.

  • B. The DHCP server has not been activated.

  • C. The DHCP server does not need to be authorized because it's running on a member server.

  • D. The scope has not been activated.

A9:

Answer D is correct. Before clients can lease an IP address, the scope must be activated. Answer A is incorrect because scopes are not authorized. Answer B is incorrect because servers are authorized, not activated. Answer C is incorrect because DHCP servers must still be authorized when the service is installed on a member server.

Question 10

Your network consists of 100 Windows 2000 computers, 25 Windows 95 computers, and 3 Windows 2000 servers. DHCP is used on the network to automate TCP/IP configurations on all client computers. You want to meet the following requirements:

  • All client computers will be accessible by the FQDN.

  • Host and PTR records should be automatically updated in DNS by Windows 2000 clients.

  • Records should be automatically removed from DNS when IP address leases expire.

  • The DHCP server will update DNS for those clients that do not support dynamic updates.

You perform the following tasks:

  • Configure the DHCP server to discard forward lookups when leases expire.

  • Configure the DHCP server to update DNS only if the DHCP client requests it.

  • Configure the 015 DNS Domain Name option.

Which of the requirements are met? [Choose all that apply.]

  • A. All client computers are accessible by their FQDNs.

  • B. Host and pointer records are automatically updated in DNS by Windows 2000 clients.

  • C. Records are automatically removed from DNS when leases expire.

  • D. The DHCP server will update DNS for those clients that do not support dynamic updates.

A10:

Answers B and C are correct. By selecting the option to discard forward lookups when leases expire, records in the DNS zone file will be automatically removed when the lease duration expires. Windows 2000 clients by default will update their own records in the DNS database. Answers A and D are incorrect because Windows 95 clients cannot update their own records, and the DHCP server isn't configured to do so on their behalf. As a result, not all clients will be accessible by their FQDN.
