Exam Prep Questions

Question 1	A DHCP server is running on your network. The range of IP addresses within the scope far exceeds the number of DHCP clients on the network. However, you notice that the number of IP address lease requests is very high. Where should you begin looking to determine why this is occurring? A. Check the Event Viewer for any DHCP- related messages. B. Verify that the lease duration isn't configured with a low value. C. Run System Monitor to view the performance of the server. D. Run Network Monitor to capture DHCP-related traffic.
A1:	Answer B is correct. The first thing that should be verified is that a shorter lease duration has not been configured. Because the number of IP addresses exceeds the number of DHCP clients, the lease duration can be increased. After that has been verified, you can begin using the other tools to troubleshoot the problem if it continues. Therefore answers A, C, and D are incorrect. After you have verified that the lease duration is properly configured, you can choose to follow up using one of the other options.
Question 2	Your network consists of two subnets: SubnetA and SubnetB. Each has its own DHCP server. You configure the scope on DHCP1 for SubnetA. Users are leasing an IP address but report that they cannot access any resources outside of their own subnet. How can you most easily solve the problem? A. Activate the scope on DHCP1. B. Configure the default gateway on each workstation. C. Configure the 003 router option on DHCP1. D. Configure the 006 DNS server option on DHCP1.
A2:	Answer C is correct. If clients have not been configured with the IP address of the default gateway, they cannot access resources outside of their local subnet. Answer A is incorrect because the clients are already successfully leasing IP addresses from the server. Answer B would solve the problem but would not be the easiest solution; therefore, it is also incorrect. Answer D is incorrect because configuring the DNS server option allows clients to resolve hostnames but doesn't give them access outside of the local subnet.
Question 3	You recently installed the DHCP Server service on one of your member servers in the domain. You notice that the DHCP service is constantly being shut down and the server cannot lease IP addresses to DHCP clients. 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.
A3:	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 by a member of the Enterprise Admins group . Answers A, B, and D are incorrect because none of these problems would cause the DHCP service to shut down.
Question 4	A DHCP server is used to assign IP addresses to clients and member servers on the network. Three of the member servers host print devices. How can you ensure that these print servers lease the same IP address from the DHCP server? A. Exclude the IP addresses from the scope. B. Create a separate scope for each of the print servers. C. Create a client reservation for each print server. D. Configure the DHCP options for the scope.
A4:	Answer C is correct. By creating a client reservation for each of the member servers, you ensure that they will always lease the same IP address from the DHCP server. Therefore, answers A, B, and D are incorrect.
Question 5	You have recently deployed a DHCP server to centralize the administration of all IP addresses on the network. Before this, they were all statically configured. All users are successfully leasing IP addresses, but they now report that they can no longer print to the network interface printers. Upon examining the printers' properties, you notice they have been assigned incorrect IP addresses. What should you have done? A. Defined separate scopes for each of the print devices B. Created client reservations for the print devices C. Excluded the IP addresses of the print devices from the scope D. Created client exclusions for the print devices
A5:	Answer B is correct. To ensure that the IP address of the network interface printers did not change when the DHCP server was placed on the network, client reservation should have been defined. Answer A is incorrect because defining additional scopes does not address the problem. Answer C is incorrect because excluding the IP addresses means that the DHCP server will never offer them to DHCP clients. Answer D is incorrect because there is no such option in DHCP called a client exclusion.
Question 6	Your network consists of multiple subnets connected by routers. You have finished installing a Windows Server 2003 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.
A6:	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 7	Several DHCP servers are being deployed in different domains throughout the forest. To which group must you belong to authorize the DHCP servers? A. DNSUpdateProxy B. Enterprise Admins C. Domain Admins D. Administrators
A7:	Answer B is correct. To authorize DHCP servers throughout the forest, the user account that you log on with must be a member of the Enterprise Admins group. Therefore, answers A, C, and D are incorrect.
Question 8	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 that 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
A8:	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 9	Your network consists of three Unix servers that provide name -resolution services. The servers are all configured with static IP addresses. How can you ensure that the DHCP server does not assign these three IP addresses to any DHCP clients on the network? A. Configure client reservations for the three Unix servers. B. Exclude the three IP addresses from the scope. C. Place the Unix servers on a separate subnet. D. Create a superscope for the three IP addresses.
A9:	Answer B is correct. To ensure that the IP addresses of the Unix servers are not leased to any DHCP clients, exclude the three IP addresses from the scope. Answer A is incorrect because client reservations are configured for the DHCP clients that need to lease the same IP address. Answer C is incorrect because placing the Unix servers on a different subnet will have no impact on the IP addresses leased by the DHCP server. Answer D is incorrect because superscopes are created to support multinetted environments.
Question 10	Two DHCP servers are configured on a network with two subnets. How can you configure the scopes so that the DHCP servers can provide fault tolerance for one another? A. Configure replication to occur between the two DHCP servers. B. Nothing needs to be done because DHCP servers on the same network share scope information, to provide fault tolerance. 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.
A10:	Answer C is correct. By configuring each DHCP server with a range of IP addresses from the remote subnet, you can provide some level of fault tolerance. Each server should be configured with 80% of the IP address for the local subnet and 20% of the IP address for the remote subnet, to avoid IP address conflicts. Answers A and B are incorrect because DHCP servers do not replicate, nor do they share scope information. Answer D is incorrect because clients are not configured with the IP address of DHCP servers.
