DNS Soru 4:

Litware, Inc. is a large, multinational corporation with its headquarters in Chicago and

large offices all over the world. The Singapore office is experiencing rapid expansion.

Singapore has considerable autonomy and users in Singapore seldom access resources in

Chicago. Users in Chicago access resources in Singapore sporadically. However, when

they do access these resources, they need to be able to do so without undue delay.

To reduce replication traffic over wide area network (WAN) links, the Delegation Of

Control Wizard has been used to create the child DNS zone singapore.litwareinc.com,

for which the Singapore domain controllers are authoritative. Both the singapore.litwareinc.

com and the litwareinc.com zones are Active Directory–integrated.

Users in Chicago report that access to resources in Singapore is becoming increasingly

slow as the Singapore operation expands. How can you improve access to Singapore

without unduly increasing network traffic?

A. Create a secondary DNS server for singapore.litwareinc.com in the Chicago office.

B. Install a caching-only server in Chicago.

C. Install a stub server for singapore.litwareinc.com in Chicago.

D. Configure a forwarder in Chicago to forward queries to a DNS server in Singapore.
