Explanation

Explanation: DHCP scope is a range of Internet Protocol (IP) addresses that are available to be leased or assigned to Dynamic Host Configuration Protocol (DHCP) clients by the DHCP service. You can configure a DNS server to forward all name resolution requests it cannot resolve itself to a server called a forwarder. If your DNS server uses a forwarder, the requests sent by your server to the forwarder will be recursive queries. It is mentioned in the question that DNS queries on the Windows Small Business Server 2003 computer are functioning, but not DNS lookups for domains in the internet. You need to configure forwarders to point to the ISP's name servers.This is what is required to ensure that client computers can properly resolve internal and external fully qualified Incorrect answers: B: DHCP scope is a range of Internet Protocol (IP) addresses that are available to be leased or assigned to Dynamic Host Configuration Protocol (DHCP) clients by the DHCP service. However, you first need to set up DNS forwarders. C: This option will not ensure access to the Internet at all times for all of the company computers. D: Making use of reserved IP addresses does not necessarily mean that the client computers will be able to access the Internet at all times.
