Your network contains an Active Directory domain named adatum.com.
You have a standard primary zone named adatum.com.
You need to provide a user named User1 the ability to modify records in the zone. Other users must be
prevented from modifying records in the zone.

What should you do first?

A.
Run the Zone Signing Wizard for the zone.

B.
From the properties of the zone, modify the start of authority (SOA) record.

C.
From the properties of the zone, change the zone type.

D.
Run the New Delegation Wizard for the zone.

Explanation:

The Zone would need to be changed to a AD integrated zone When you use directory-integrated zones, you
can use access control list (ACL) editing to secure a dnsZone object container in the directory tree. This feature
provides detailed access to either the zone or a specified resource record in the zone. For example, an ACL for
a zone resource record can be restricted so that dynamic updates are allowed only for a specified client
computer or a secure group, such as a domain administrators group. This security feature is not available with
standard primary zones
DNS update security is available only for zones that are integrated into Active Directory. After you integrate a
zone, you can use the access control list (ACL) editing features that are available in the DNS snap-in to add or
to remove users or groups from the ACL for a specific zone or for a resource record.
Standard (not an Active Directory integrated zone) has no Security settings:

You need to firstly change the “Standard Primary Zone” to AD Integrated Zone:

Now there’s Security tab:
