While creating a DHCP scope, you create an exclusion range for the printers on your network. You also create client reservations for each printer. None of the printers receives an IP address from DHCP. How should you resolve the problem? a. R: b. Remove the exclusion range for the printers.

EXPLANATION: Addresses that are excluded could not be leased
under client reservations. In this scenario, you should configure client reservations but not exclusions.
You configure a DHCP scope with a 15-day lease period and a 21-bit subnet mask. How can you change the lease period so that it is unlimited with the least amount of administrative effort and DHCP server downtime? a. Delete the existing scope: b. Edit the properties of the scope within the DHCP console, and change the lease period to unlimited.

EXPLANATION: A Dynamic Host Configuration Protocol (DHCP) scope
can be edited to change the lease period. If a change were required to the subnet mask, the scope would have to be deleted and re-created.
From a DHCP server, a client receives an address that has a lease period of 6 days. At what point will the client first attempt to renew the lease? a. 1 day b. 5 days c. 2 days d. 3 days: d. 3 days

EXPLANATION: Dynamic Host Configuration Protocol (DHCP) clients will attempt to renew the lease with the DHCP server that originally provided the lease when 50 percent of the lease duration has expired.
You are the administrator of a Microsoft Windows Server 2003 network. The network consists of two Windows Server 2003 computers named Toledo and Cleveland and 275 Microsoft Windows XP Professional computers. Toledo is a DHCP server. The DHCP server provi: a. On the DHCP server, create and activate a multicast scope with a range of Class D addresses.

EXPLANATION: Dynamic Host Configuration Protocol (DHCP) has been
extended to support the assignment of Class D multicast addresses. You should create a multicast scope. The DHCP server would then dynamically assign multicast IP addresses to all clients that were configured to receive a multicast address.
You administer a network that has 75 client computers configured to dynamically receive IP address configuration. The DHCP server has been configured using a DHCP scope with a configured IP address range of 170.34.32.1 to 170.34.32.255 and a 24-bit mask.: a. Activate the scope.

EXPLANATION: A scope must be activated before it can be used to
assign addresses, and a Dynamic Host Configuration Protocol (DHCP) server must be authorized if it is part of an Active Directory domain. Increasing the lease duration or re-creating the scope does not affect this situation.
A DHCP server that is located on a member server and that is a member of a workgroup must be authorized before it can respond to DHCPDISCOVER messages? a. True b. False: b. False

EXPLANATION: Dynamic Host Configuration Protocol (DHCP) servers
that are part of an Active Directory domain must be authorized. There is no authorization process for DHCP servers that are members of a workgroup.
You are the administrator of a Microsoft Windows Server 2003 network. The network consists of two Windows Server 2003 computers, named server 1 and server 2, and 200 Microsoft Windows XP Professional client computers. Server 2 is a DHCP server that provi: c. 237.10.10.4

EXPLANATION: The multicast address range is 224.0.0.0 through 239.255.255.255
When a DHCP-enabled client is unable to contact a DHCP server and begins using an APIPA address, when will the client attempt to contact a DHCP server again? a. Every 30 minutes b. Every 5 minutes c. Never d. Every 10 minutes: b. Every 5 minutes

EXPLANATION: When a client receives an address through Automatic
Private IP Addressing (APIPA), it will attempt to contact a Dynamic Host Configuration Protocol (DHCP) server at 5-minute intervals.
You add new computers to your DHCP-enabled network; soon after, you discover that users have occasional problems accessing resources on the network using TCP/IP. Which of the following solutions could solve this problem? a. Add addition: a. Add additional IP addresses to the DHCP scope to include enough addresses for all computers.

EXPLANATION: All client computers must receive a unique Internet Protocol (IP) address, and the scope must contain an adequate number of addresses. If the number of requests for addresses exceeds the number of addresses contained in the scope, clients begin receiving Automatic Private IP Addressing (APIPA) addresses and they are not able to communicate on the network.
You are a network administrator and you have statically assigned IP addresses to each of your network servers. What should you do to ensure that DHCP does not assign the addresses you have statically assigned to the network servers? a. Exclud: a. Exclude the addresses of the servers from the DHCP scope.

EXPLANATION: Statically assigned IP addresses that fall within the
Dynamic Host Configuration Protocol (DHCP) scope address range should be excluded to ensure that the DHCP server does not assign them to a DHCP-enabled client.
When would a client computer receive a DHCPNACK message? a. When a DHCP server receives a request from a client to renew a lease and is in the process of completing the renewal b. When a DHCP server receives a request from a client to r: b. When a DHCP server receives a request from a client to renew a lease but cannot renew the lease

EXPLANATION: The DHCPNACK is used to inform a client that its
request for lease renewal cannot be fulfilled. The DHCPOFFER is used to answer a DHCPDISCOVER message.
You are the administrator of a Microsoft Windows Server 2003 network that consists of two subnets that are connected by a router. Active Directory directory service is implemented on the network. The DHCP server is installed on subnet 1, and the DHCP rel: c. The DHCP relay agent is configured with an incorrect IP address for the DHCP server.

EXPLANATION: The most likely cause of this problem is that the Dynamic Host Configuration Protocol (DHCP) relay agent was incorrectly configured. The DHCP relay agent must be configured with the IP address of the DHCP server. If this is done incorrectly, communication cannot occur between the DHCP relay agent and the DHCP server.
APIPA addresses come from which address range? a. 172.16.0.0 through 172.31.255.255 b. 169.254.0.0 through 169.254.255.255 c. 10.0.0.0 through 10.255.255.255 d. 192.168.0.0 through 192.168.255.255: b. 169.254.0.0 through 169.254.255.255

EXPLANATION: Automatic Private IP Addressing (APIPA) will assign addresses in the range of 169.254.0.0 through 169.254.255.255. The addresses 172.16.0.0 through 172.31.255.255, 10.0.0.0 through 10.255.255.255, and 192.168.0.0 through 192.168.255.255 are private IP addresses and cannot be assigned through APIPA.
As a network administrator, you are deploying DHCP on your Microsoft Windows Server 2003 network. You want to ensure that all of your print devices receive the same IP address each time they initialize. What step should you take to ensure that DHCP assig: a. Configure client reservations for each print device interface.

EXPLANATION: Client reservations map a specific IP addresses to a specific hardware address. Dynamic Host Configuration Protocol (DHCP) then assigns the same IP address to each print device for each mapping. (Discussion starts on page 18.)
The DHCP Server service is installed on Microsoft Windows Server 2003 by default. a. True b. False: b. False

EXPLANATION: The Dynamic Host Configuration Protocol (DHCP)
Server service can be installed through Add And Remove Windows components in the Control Panel or through the Configure Your Server page.
DHCP is based heavily on which protocol? a. Address Resolution Protocol (ARP) b. Reverse Address Resolution Protocol (RARP) c. Bootstrap Protocol (BOOTP) d. Domain Name System (DNS): c. Bootstrap Protocol (BOOTP)

EXPLANATION: Dynamic Host Configuration Protocol (DHCP) is based heavily on Bootstrap Protocol (BOOTP).
When a Microsoft Windows XP client that is configured to use a DHCP server initializes, what type of message will it broadcast first? a. DHCPREQUEST b. DHCPINFORM c. DHCPDISCOVER d. DHCPNACK: c. DHCPDISCOVER

EXPLANATION: A DHCP-enabled client will broadcast a DHCPDISCOVER message in an attempt to locate a Dynamic Host Configuration Protocol (DHCP) server. DHCPREQUEST messages are sent to the DHCP server to request parameters from one server while declining a lease offer from another server.
A network administrator has a single Class C address space, which is 194.10.10.0. The network consists of 150 users who are logged on to the network at all times and 150 sales users who have portable computers and who are periodically logged on to the ne: c. Decrease the default lease period to 1 day.

EXPLANATION: With a single Class C address, only 254 possible addresses are available. Because you have a total of 300 potential users on your network, you should decrease the lease period so that addresses that are no longer in use will be readily available.
You must deploy DHCP on your network. The network has three physical segments that are separated by a Microsoft Windows Server 2003 server that is configured to act as a router. You configure three subnets, or multinets, using the following range of: b. Define a superscope that includes a separate scope for each address range.

EXPLANATION: A superscope is an administrative grouping of multiple DHCP scopes or multinets. Creating a scope for each subnet is incorrect because each scope must contain separate address spaces. Configuring DHCP on three computers, one for each subnet, would not allow the DHCP server to use multiple scopes.
If a client on a routed network is not on the same segment as the DHCP server, which of the following can be configured to allow the client to obtain DHCP addressing information from the DHCP server? a. DHCP helper address b. Def: d. DHCP relay agent

EXPLANATION: Dynamic Host Configuration Protocol (DHCP) relies heavily on broadcast messages that are not typically allowed to pass through a router. A DHCP relay agent can be configured with the address of the DHCP server. The DHCP relay agent will listen for DHCPDISCOVER, DHCPREQUEST, and DHCPINFORM messages. The DHCP relay agent will forward the messages across the router to the DHCP server as a unicast packet.
You are a network administrator and have been asked to configure a DHCP relay agent. What option in Administrative Tools would you use to complete this task? a. DHCP management console b. DHCP relay manager c. Routing And Remote A: c. Routing And Remote Access

EXPLANATION: To configure the Dynamic Host Configuration Protocol (DHCP) relay agent, use Routing And Remote Access in Administrative Tools.
What is the default lease period for a DHCP server running on Microsoft Windows Server 2003? a. 24 hours b. 3 days c. 8 days d. 5 days: c. 8 days

EXPLANATION: The default lease period for a Dynamic Host Configuration Protocol (DHCP) server running on Windows Server 2003 is 8 days.
An administrator has configured a DHCP server on a computer that is running Microsoft Windows Server 2003 in an Active Directory domain. A scope has been configured that has a valid range of addresses from 192.168.1.1 through 192.168.1.254. DHCP-enabled: d. Authorize the DHCP server in Active Directory.

EXPLANATION: A Dynamic Host Configuration Protocol (DHCP) server
in an Active Directory domain must be authorized before it can respond to DHCPDISCOVER messages from DHCP-enabled clients.
A valid range of addresses and associated configuration options that a DHCP server is configured to assign to DHCP-enabled clients is referred to as a what? a. DHCP scope b. Client reservation c. Client lease d. Scope option: a. DHCP scope

EXPLANATION: A Dynamic Host Configuration Protocol (DHCP) scope
is a set of Internet Protocol (IP) addresses and associated configuration information that can be supplied to DHCP clients. A client reservation is a DHCP scope option that provides the same IP address to a client each time based on the clientâ€™s hardware address. A client lease contains the addressing information provided by the DHCP server to a DHCP client. Scope options are optional configuration parameters that can be configured and associated with a DHCP scope.
You are the network administrator for Wingtip Toys. Your network consists of 85 desktop client computers and 55 portable computers, all of which run on Microsoft Windows XP Professional. Only 20 of the users of the portable computers are ever in the offi: c. Create one scope that has two user classes, each with different lease durations.

EXPLANATION: Creating one scope with two user classes will allow an administrator to assign different configuration parameters to each user class. User classes are administrative groupings created by the network administrator. Thus, the group of portable computer users could be assigned a shorter lease duration than the clients that use desktops.
Your Microsoft Windows Server 2003 network has 100 clients and uses DHCP with a scope that is configured to issue an internal address in the range of 192.18.1.0 through 192.168.1.254. You have been asked to set the DCHP lease period to the longest possib: c. Set the DHCP lease period to unlimited.

EXPLANATION: The Dynamic Host Configuration Protocol (DHCP) lease period can be set to intervals between 1 minute and 999 days, or it can be set to unlimited. In this case, you would set the lease period to unlimited. (Discussion starts on page 5.)
DHCP is based heavily on which protocol? A Address Resolution Protocol (ARP) B Reverse Address Resolution Protocol (RARP) c. Bootstrap Protocol (BOOTP) d Domain Name System (DNS): c. Bootstrap Protocol (BOOTP)

EXPLANATION: Dynamic Host Configuration Protocol (DHCP) is based heavily on Bootstrap Protocol (BOOTP).
A network administrator configures a DHCP server that has a scope of addresses 172.16.1.0 through 172.16.1.255. The first 10 addresses in this range were previously assigned to servers and print devices that require static IP address configuration. What: B Configure an exclusion range for the addresses that have been assigned previously.

EXPLANATION: To prevent the Dynamic Host Configuration Protocol (DHCP) server from assigning addresses that have been statically assigned and included in the address pool, you must configure an exclusion range that includes the statically assigned addresses.
