You have a server named CorpNet_DHCP that runs WIndows Server 2016 and has the DHCP Server role installed on it. You have another server named CorpNet_WDS with the Windows Deployment Service (WDS) server role installed. Both servers are located on the same subnet as client computers. You need to make sure that clients can perform a PXE boot from CorpNet_DHCP and install the image located on CorpNet_WDS. Which two additional IPv4 options should you configure in DHCP? (Select two. Each answer is part of the complete solution.)
- 066 Boot Server Host Name - 067 Bootfile Name
Drag the DHCP mechanism on the left to the appropriate description on the right. (Each mechanism can be used once, more than once, or not at all.)
- Associates a client's MAC address with an IP address the client should always receive: Reservation - Specifies computers that can be DHCP server clients: Filter - Ensures that a client always receives the same IP address from the DHCP server: Reservation - Prevents the DHCP server from assigning certain IP addresses: Exclusion - Specifies computers that can be DHCP server clients: Filter - Identifies IP addresses within the range that cannot be assigned: Exclusion Reservation, Filter, Reservation, Exclusion, Filter, Exclusion
The DHCP server and the client use broadcasts to communicate with each other. Clients go through four steps to obtain an address from a DHCP server. Drag steps from the left pane to the right pane to arrange them in the order they occur when a client obtains IP configuration from a DHCP server. Each step may be used once, more than once, or not at all.
- DHCP Discover, DHCP Offer, DHCP Request, DHCP ACK - Discover, Offer, Request, ACK
You are the administrator of a large network with one location serving several thousand users. You have 100 Windows servers. Your users have Windows desktops. You are installing another server into the network. The server's role as a web server that will be hosting the company intranet site. The server will require an IP address on the 10.1.1.0/24 subnet. At present, this subnet contains only servers, and one of the servers is providing addresses through DHCP. You need to assign this server an IP address. Which of the following are the best practice options for assigning the IP address to the web server? (Select two. Each answer is a complete solution.)
- Manually configure the IP address on the web server. Create an exclusion on the DHCP server. - Configure the web server to use DHCP. Create a reservation on the DHCP server.
Bryce is the system administrator for a network with a single Active Directory domain. The network has just expanded to include an additional subnet. Bryce has installed a new server on the new subnet. It is running Windows Server, and he has configured it as a DHCP server. When he checks the server icon in the DHCP Management console, he notices the server has a down icon. The DHCP server service has started, but the server still does not respond to DHCP lease requests. What should Bryce do to solve the problem?
Ask a member of the Enterprise Admins group to authorize the server.
Rachel is a junior system administrator for a network with a single Active Directory domain. The network has just expanded to include an additional subnet. Rachel has installed a new server running Windows Server 2016 on the new subnet and configure it as a DHCP server. When she checks the server icon in the DHCP Management console, she notices the server has a down icon. The DHCP server has started, but the server does not respond to DHCP lease requests. What should Rachel do to solve the problem?

Nadine is the systems administrator for a network with a single subnet. The subnet uses 192.168.1.0 with a mask of 255.255.255.0. The network has 10 servers running Windows Server. Srv1 currently provides both DHCP and DNS services. Nadine wants to increase the fault tolerance for her DHCP servers. She installs a new server, Srv11, and configures it for DHCP. She configures a scope on Srv11 to match the scope on Srv1 and then excludes half of the addresses in the scope on Srv1 and the other half of the addresses on the Srv11. Nadine decides to test her solution and shuts down Srv1. As a test, she forces a workstation to release its IP address and request a new one. She finds that the workstation has the IP address 169.254.0.15 with a mask of 255.255.0.0. What should Nadine do to fix the problem?
Authorize Srv11.
Which of the following is a valid IPv6 address?
FEC0::AB:9007
You are the administrator of what will become a large Windows Server network that uses the TCP/IP protocol. Currently, the network consists of three Windows Servers and 50 Windows workstations all on the same subnet. During the last meeting you had with the CIO, it was determined that company growth would mean adding workstations and printers to the existing network for a total of 235 devices. The existing hardware will be used on the network as the new devices are added. How should you assign IP addresses to the workstations on the network to minimize administration?
Configure each workstation to use DHCP. Install a DHCP server and configure a single scope. Configure reservations for each printer.
Jodie is the administrator for a single DHCP server for a network of three subnets. The DHCP server is configured with three scopes, one for each subnet. The three subnet addresses are 192.168.1.0, 192.168.2.0, and 192.168.3.0 using the default subnet mask. In addition to assigning IP addresses to network hosts, the DHCP server needs to configure the following: - DNS server address for all hosts: 192.168.1.11 - Default gateway for hosts on the 192.168.2.0 subnet: 192.168.2.1 - Default gateway for hosts on the 192.168.2.0 subnet: 192.168.2.1 - Default gateway for hosts on the 192.168.3.0 subnet: 192.168.3.1 How should you configure the DHCP scope options to minimize administrative effort?
Configure server options to deliver the DNS server address. Configure scope options for each scope to deliver each subnet's designated default gateway address.
Anthony administers a single DHCP server for a network of three subnets. The DHCP server is configured with three scopes, one for each subnet. The three subnet addresses are 192.168.1.0, 192.168.2.0, and 192.168.3.0 and use the default subnet mask. The server delivers IP addressing and other TCP/IP configuration information. All hosts on the subnets should be configured to use 192.168.1.11 for the DNS server. In addition, the default gateway for hosts within a subnet should point to the first IP address on the subnet. The default gateway for hosts on subnet 192.168.1.0 should be set to 192.168.1.1. The default gateway for hosts on subnet 192.168.2.0 should be set to 192.168.2.1. The default gateway for hosts on subnet 192.168.3.0 should be set to 192.168.3.1. All clients run Windows 10. How should Anthony configure DHCP to minimize administrative effort?
Configure the server's scope options to deliver the DNS server value. Configure scope options for each scope to deliver the default gateway value.
You are the network administrator for a single domain network with 15 servers running Windows Servers, 190 Windows clients, and 10 Linux workstations. Windows servers on the network provide DNS and DHCP services. The Linux workstations run a custom application that validates the workstation identity based on its IP address. For the program to run successfully, each workstation must have the same IP address each time it runs the program. Which of the following actions can you take to meet this requirement?
Create a reservation for each Linux workstation. Configure the workstations to receive IP addresses from DHCP.
Rachel has a DHCP server named CorpNet_DHCP that runs Windows Server 2016. She has a single IP subnet. CorpNet_DHCP has an IPv4 scope named ScopeA. ScopeA has an IP address range of 192.168.1.10 to 192.168.1.200 and a subnet of 255.255.255.0. She needs to create a second logical IP network on the subnet. The subnet will use an IP address range of 192.168.2.10 to 192.168.2.200 and a subnet of 255.255.255.0. What should Rachel do?
Create a second scope and then create a superscope.
Rachel is the network administrator for CorpNet.xyz. She supports the main office. A DHCP server named DHCP1 provides IP addresses from the 192.168.1.0./24 scope. Management informs Rachel that they intend to add five hundred new users at the main office. She intends to migrate users to the 10.1.0.0/16 network. She creates a new scope on DHCP1 for the 10.1.0.0/16 network. She needs to ensure that clients at the main office can receive addresses from either scope until all of the new users have arrived. What should Rachel do?
Create a superscope.
You are the network administrator for eastsim.com. The network consists of a single Active Directory domain. All of the servers run Windows Server 2016. All of the clients run Windows 10. There is one main site, and there are several satellite locations. The organization has decided to implement IPv6. IPv6 will be used to connect multiple integral segments, but not to connect to the internet. All IPv6 addresses should be centrally assigned. You have installed the DHCP role on a member server in the main site. You need to create an IPv6 scope that will distribute site-local addresses to client computers. What should you do?
Create an IPv6 scope and identify a prefix of FC00::/64.
You have a network with 50 workstations. You want to automatically configure workstations with the IP address, subnet mask, and default gateway values.

You are a junior systems manager for your company's network. There are 600 workstations running Windows 10, and they receive services from 20 Windows servers. The network is split into 10 subnets. You've configured the DHCP servers on 10 servers, one for each subnet. However, shortly after you finish configuring the servers, your boss receives reports that workstations are not able to communicate properly with other workstations. Your boss investigates and soon discovers that the subnet masks you assigned in the DHCP scopes are incorrect. Your boss tells you to correct your error with the least amount of administrative effort. What should you do?
Delete all of the scopes and start over.
You manage the westsim.com domain. The network has a single subnet with five servers running Windows Server. The 100 client computers are all Windows desktops. One of the servers is configured as a DHCP server configured with a single scope for the 10.0.0.0/24 subnet. Your network has three printers with built-in print servers. These printers are configured as DHCP clients. You want to make sure that each printer gets the same IP address each time it starts up. You configure an exclusion range of 10.0.0.12 to 10.0.0.14 for the printers. You also configure a reservation for each printer. You are informed that no one is able to connect to the printers. You use management software and find that none of the printers are assigned appropriate IP addresses. What should you do?
Delete the exclusion range on the DHCP server.
You are the network administrator for CorpNet.xyz. The company has six internal networks that are routable within the company and use IPv4 private addressing. In preparation for the transition to IPv6, you have been asked to configure DHCP to support IPv6 address distribution. You need to create a new IPv6 scope on the DHCP server. The prefix for the scope must support private addressing and be routable on the internal network. Which prefix should you use?

Ralph is implementing a DHCP server for a segment. His segment's IP address is 192.168.1.0. His default gateway address is 192.168.1.254. His DNS server address is 192.168.1.1. His default gateway is configured as a NAT router to translate addresses between network segments. Ralph configures the 03 Router option on his DHCP server so it can deliver the IP address of the default gateway to workstations. After configuring his workstations to get their IP addressing information dynamically, his users complain that they are unable to access websites on the internet. How can Ralph resolve this problem?
He must configure his DHCP server with an option that delivers the IP address of the DNS server (option 06).
You have configured your organization's DHCP server to dynamically assign IP addresses to DHCP clients using a lease duration of four days. You are using a Windows server for DHCP, and the default lease time is eight days. What impact, if any, will this have on the network?
Increased network traffic
You want to configure your network router such that network hosts obtain the interface ID, subnet prefix, default gateway, and all other configuration information from a DHCPv6 server. How should the M and O flags be set on the router to accomplish this?

You want to configure your network router so that IPv6 addressing information is assigned to network hosts with the following process: 1. The interface ID is set automatically. 2. The subnet prefix and default gateway are retrieved from the router RA (Router Advertisement) message. 3. DNS and other configuration information are retrieved from a DHCPv6 server. How should you set the M and O flags on the router to accomplish this?
Set the M flag to 0 and the O flag to 1. (MOO1)
You are installing DHCP in four subnets. Three of the subnets have Windows desktop computers, and the fourth subnet has only Windows laptop computers. On the subnet with the laptops, you want any computer that has not logged on in two days to release its IP address. On the desktop subnets, you want computers that have not logged on in 30 days to release their IP addresses. How should you configure the DHCP scopes?
Set up one scope for each subnet and set the lease period as a part of each scope's configuration.
A workstation configured to use DHCP for IP addressing sends a DHCP Discover frame on the local network segment. The frame is received by the DHCP service running on a Windows Server 2012 R2 system. What happens next?
The DHCP server responds with a DHCP Offer.
Your network routers are configured to use stateful DHCPv6. When a DHCPv6 client first starts up, it sends a solicit packet to the DHCPv6 server to solicit IP addressing information. The DHCPv6 server responds with an advertise packet. What happens next?
The DHCPv6 client responds with a request packet.
