Client system sends a recursive query message with the web address to the DNS server as specified in the system's TCP/IP configuration. d. Client's DNS generates another iterative query and transmits it to the second-level domain server. Assuming second-level server is authoritative server for the zone containing the web address, it consults its records to determine IP address of requested system, and then messages back to the client's DNS server. e. Client's DNS receives reply from the authoritative server and transmits the IP address back to the client. The client's web browser now knows the IP address of the web server.
c. Client system sends a recursive query message with the web address to the DNS server as specified in the system's TCP/IP b. Client's DNS server checks records for authoritative source for the zone containing the web address. DNS server sends iterative query to a root server. Root server responds with referral to top-level domain server address. a. Client's DNS server, with the top-level domain server address, generates a new iterative query and sends it to the top-level domain server. The top-level domain server responds with a referral to the second-level domain server. d. Client's DNS generates another iterative query and transmits it to the second-level domain server. Assuming second-level server is authoritative server for the zone containing the web address, it consults its records to determine IP address of requested system, and then messages back to the client's DNS server. e. Client's DNS receives reply from the authoritative server and transmits the IP address back to the client. The client's web browser now knows the IP address of the web server. C, B, A, D, E

3. Order the steps to create a DHCP scope. a. Expand the server and IPv4 nodes. Right-click the IPv4 node and, from the context menu, select New Scope. The New Scope Wizard appears. Type a name for the scope into the Name text box and click Next. b. Configure IP address range, from starting to ending IP address. Configure the subnet mask. c. In the Server Manager window, click Tools and then click DHCP. The DHCP console appears. d. Specify the length of leases for the scope's addresses. Specify the default gateway, DNS, and activate the scope. e. Configure the IP exclusion range, from starting to ending IP address. You can also specify a delay interval between the server's receipt of DHCPDISCOVER messages and its transmission of DHCPOFFER messages.
