Question 1

You administer your company's Windows 2003 domain. The domain contains 10 Windows Server 2003

computers, 750 Windows XP Professional computers, and 300 Windows NT 4.0 Workstation computers Four

of the Windows Server 2003 computers are DHCP servers, and two of the Windows Server 2003 computers

are DNS servers. All network computers are configured to use DHCP. All four DHCP servers are configured

with scopes for every subnet in the network.

You configure the DHCP servers to always register and update client computer information in DNS. To increase

security, you configure DNS to only allow secure updates.

Immediately following this, you discover that the resource records for the DHCP clients are no longer updated

when IP addresses change. You want the resource records for the client computers to have the most recent

information.

What should you do?

Options :

A : Add the computer accounts of the four DHCP servers to the DNSUpdateProxy global security group

B : Add the computer accounts of the two DNS servers to the DHCP Users domain local security group

C : Add the computer accounts of the four DHCP servers to the DNSAdmins domain local security group

D : Configure the four DHCP servers to enable updates for DNS client computers that do not support dynamic update. Configure the DHCP server to not release the DHCP lease for Windows XP Professional computers and the Windows NT 4.0 Workstation computers at shutdown. Configure the two DNS servers to use a Time to Live (TTL) interval on resource records that are shorter than the lease time used by the DHCP servers.

Answer: A

C :

The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.

D :

Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.
