Your network contains an Active Directory domain named contoso.com. The domain contains a domain
controller named DC1 that runs Windows Server 2012 R2. DC1 has the DNS Server server role installed.
The network contains client computers that run either Linux, Windows 7, or Windows 8. You have a standard
primary zone named adatum.com as shown in the exhibit. (Click the Exhibit button.)
You plan to configure Name Protection on all of the DHCP servers.
You need to configure the adatum.com zone to support Name Protection.
Which two configurations should you perform from DNS Manager? (Each correct answer presents part of the
solution. Choose two.)
A.
Sign the zone.
B.
Store the zone in Active Directory.
C.
Modify the Security settings of the zone.
D.
Configure Dynamic updates.
E.
Add a DNS key record
Explanation:
Name protection requires secure update to work. Without name protection DNS names may be hijacked.
You can use the following procedures to allow only secure dynamic updates for a zone. Secure dynamic update
is supported only for Active Directoryintegrated zones. If the zone type is configured differently, you must
change the zone type and directory-integrate the zone before securing it for Domain Name System (DNS)
dynamic updates.1. (B) Convert primary DNS server to Active Directory integrated primary
2. (D) Enable secure dynamic updates
DHCP: Secure DNS updates should be configured if Name Protection is enabled on any IPv4 scope
