VCP-310,640-802 dumps and 350-001 testking

You need to design a DNS name resolution strategy. You must configure the DNS
server on the peripheral network to meet the case study scenario.

What should you do?

A. Configure a secondary zone for the Willow Bridge, Inc. internal network.
B. Configure the peripheral DNS server to host the willowbridge.com zone with the A
record for WB-SR01.
C. Create a delegation to the zone on the Willow Bridge, Inc. internal network.
D. Create a delegation to the zone on the Research and Development department test
network.
E. Specify the ISP's DNS server as a forwarder.
Answer: E
Explanation: WB-SR01 and WB-DB01 belong to the Willow Bridge, Inc. forest and,
hence their names must be registered with DNS servers on the Willow Bridge, Inc.
network.350-001 To enable customers to access WB-SR01, the ISP's DNS server can be
configured to host the public willowbridge.com zone which include the appropriate A
record for WB-SR01.640-802 The DNS server on the peripheral network should be configured to
forward all queries to the ISP's DNS server and not use recursion.
1. Group Policy is to be used to configure the Web-server named WB-SR01; and the
SQL server named WB-DB01.

Incorrect answers:
A: Configuring a secondary zone will result in increased resolution traffic across the
external firewall.
B: You could configure the peripheral DNS server to host the willowbridge.com zone
with the A record for WB-SR01, but this option does not take into account that the DNS
server should not host any other zones and should not be able to resolve names on either
of the Internal networks.

C: This would result in the DNS server on the peripheral network being able to resolve
names on the internal network.VCP-310 This is therefore a security risk.
D: This will result in an unnecessary security risk because it will allow the DNS server to
resolve names on the internal network.
