Q:
You are a domain administrator for your company's Active Directory domain. You plan to use a Remote Installation Service (RIS) server to deploy Windows XP Professional to 40 new client computers. You want to ensure that your Windows Server 2003 Dynamic Host Configuration Protocol (DHCP) server responds to both DHCP clients and Bootstrap Protocol (BOOTP) clients.
Which component of the DHCP console should you use to ensure that the server responds to DHCP and BOOTP clients?
The Properties dialog box of the scope for RIS clients
The Properties dialog box of the server
The scope options
The server options
A:
You should use the Properties dialog box of the scope for RIS clients. You can enable responses to BOOTP clients on the Advanced tab of the dialog box.
You should not use the Properties dialog box of the server. You can use this dialog box to enable the display of the BOOTP table. You can use the BOOTP table to define the location of RIS images, but not to enable the server to respond to BOOTP requests.
You should not use the scope options. You can use the scope options to configure specific options for BOOTP clients, but not to enable the server to respond to BOOTP requests.
You should not use the server options. You can use the server options to configure specific options for BOOTP clients, but not to enable the server to respond to BOOTP requests. Options that you configure at a server level apply to leases from all scopes. However, if you configure the same option at a server level and at a scope level, the scope-level option will override the server-level option.
Note that you can also configure a DHCP reservation to respond to BOOTP clients. You use a DHCP reservation to reserve an Internet Protocol (IP) address for a specific Media Access Control (MAC) address.
