D. DHCP administrators in Atlanta only

E. Members of the Enterprise Admins group

Answer: A, E

According to the scenario, the Atlanta office will deal with the administration of active directory. Therefore the IT staff in Atlanta is the correct answer, and "B" is incorrect..

Incorrect Options:

C and D: DHCP Administrator is a built-in group in AD that does not have the ability to authorize DHCP.

By default, Windows Server 2003 DHCP servers do not attempt to perform dynamic updates on behalf of these clients.

Incorrect Options:

A: The WINS resource record instructs the DNS service to use WINS to look up and
forward queries for host names not found in the zone database.
B: You should configure a WINS referral zone to provide a means of organizing and
distinguishing between WINS and DNS records.
C: An option that specifies the domain name that DHCP clients should use when
resolving unqualified names during DNS domain name resolution. This option also
allows clients to perform dynamic DNS updates.
