Your network contains an Active Directory domain named contoso.com.
You currently have an intranet web site that is hosted by two Web servers named Web1 and
Web2. Web1 and Web2 run Windows Server 2012.
Users use the name intranet.contoso.com to request the web site and use DNS round robin.
You plan to implement the Network Load Balancing (NLB) feature on Web1 and Web2.
You need to recommend changes to the DNS records for the planned implementation.
What should you recommend?
A.
Create a service locator (SRV) record. Map the SRV record to Intranet.
B.
Delete both host (A) records named Intranet. Create a pointer (PTR) record for each Web
server.
C.
Remove both host (A) records named Intranet. Create a new host (A) record named
Intranet.
D.
Delete both host (A) records named Intranet. Create two new alias (CNAME) records
named Intranet. Map each CNAME record to a Web server name.
Should be C – remove (A) records of old web servers and add new (A) record of new cluster.
agreed should be C.
correct one is C
You must manually register the NLB cluster name in DNS by using a host (A) or (AAAA) record because DNS does not automatically register static IP addresses.
