Question
SIMULATION You need to ensure that all DHCP clients that get an IP address from SRV1 will be configured to use DC1 as a DNS server. To complete this task, sign in the required computer or computers. Answer: Either (if there exists a DHCP scope) Solution 1: Edit an existing DHCP scope Or (if there are no DHCP scopes) Solution 2: Add and configure a new scope Solution 1: Edit an existing DHCP scope Managing scope options You can manage scope options using either the DHCP console or PowerShell. To modify scope options in the DHCP console: Step 1: In the DHCP console when connected to the DHCP server [here SRV1] you wish to manage, expand the IPv4 node, then expand the scope [here a scope if is available, otherwise use Solution 2] with the options you wish to modify. Step 2: Select the Scope Options node. Step 3: Right-click on Scope Options, then select Configure Options. Step 4: Select the option you want to configure from the list of options. Step 4a: To configure the properties of an existing option, right-click on the option, then select Properties. Step 4b: To enable or disable a setting, select the checkbox and configure the option. Step 5: On the Domain Name and DNS Servers page, specify the domain name that clients use for DNS name resolution. Specify the DNS servers by typing the hostname [here DC1] or the IP address in the correct field. Select Next. Solution 2: Add and configure a new scope Configure an IPv4 scope After you have successfully authorized your DHCP Server, you can proceed to create a new DHCP scope. Scopes are used to indicate the range of IP addresses for your DHCP server and its clients. To create a new IPv4 DHCP scope, select the relevant method and follow the steps. Here's how to create a new DHCP scope using the DHCP console. Step 1: From the Windows desktop, open the Start menu, select Windows Administrative Tools > DHCP. Step 2: Expand the name of the DHCP Server [here DHCP1], right-select IPv4, and then select New Scope. Step 3: On the New Scope Wizard welcome page, select Next. Step 4: On the Scope Name page, in the Name field, type the name of your new scope and select Next. Step 5: On the IP Address Range page, specify the range of IP addresses for your DHCP clients and specify the subnet mask, using your preferred method, select Next. Step 6: On the Add Exclusions and Delay page, specify any addresses or range of addresses that you don't want the server to distribute, select Next. [Skip with Next] Step 7: On the Lease Duration page, specify the lifespan for the IP addresses assigned to each DHCP client, select Next. [Accept Default with Next] Step 8: On the Configure DHCP Options page, select Yes, I want to configure these options now and then select Next. Tip The Configure DHCP Options page lets you configure common DHCP options including IP addresses of routers (default gateways), DNS servers, and WIN settings for your new scope. At minimum, you must configure routers and DNS servers before proceeding. Step 9: On the Router (Default Gateway) page, enter the IP address of the Gateway that DHCP clients should use, then select Add. [Skip] Step 10: On the Domain Name and DNS Servers page, specify the domain name that clients use for DNS name resolution. Specify the DNS servers by typing the hostname [here DC1] or the IP address in the correct field. Select Next. Step 11: On the WINS Servers page, enter the names and IP addresses of any WINS servers that you use in your deployment. If WINS servers aren't present in your deployment, you can select Next to skip this step. [Next to skip] Step 12: Use the Activate Scope page to activate the DHCP scope. Select Yes [here Yes], I want to activate this scope to enable your DHCP Server to immediately begin assigning IP addresses to clients. You can also activate your new scope at a later time by selecting No, I will activate this scope later. Step 13: Select Finish to exit the New Scope Wizard.
