You work as a Network Administrator at AIOTestking.com. AIOTestking.com has an Active Directory
Domain Services (AD DS) domain named AIOTestking.com. All servers in the AIOTestking.com domain
have Microsoft Windows Server 2012 R2 installed. AIOTestking.com has a corporate LAN and a
perimeter network.
A Windows Server 2012 R2 server named TESTKING-SR11 is located in the perimeter network
and hosts the corporate website. The website is publicly accessible.
A Windows Server 2012 R2 server named TESTKING-SR04 is also located in the perimeter
network. TESTKING-SR04 hosts a publicly accessible DNS zone which contains DNS records for
the corporate website.
You plan to move the corporate web site to a new server named TESTKING-SR12.
You need to change the DNS records for the corporate web site to point to TESTKING-SR12.
To minimize the time it takes for the changed DNS records to propagate to other public DNS
servers, you want to reduce the time that the DNS records are cached for.
What action should you take?

A.
In the properties of the DNS zone, change the Serial Number value on the Start of Authority
(SOA) tab.

B.
In the properties of the DNS zone, change the Refresh Interval value on the Start of Authority
(SOA) tab.

C.
In the properties of the DNS zone, change the Expires After value on the Start of Authority
(SOA) tab.

D.
In the properties of the DNS zone, change the Minimum (default) TTL value on the Start of
Authority (SOA) tab.

E.
In the properties of the DNS zone, change the TTL for this record value on the Start of Authority
(SOA) tab.
