Your network contains an Active Directory domain named contoso.com.
The domain contains a main office and a branch office.
An Active Directory site exists for each office.
All domain controllers run Windows Server 2012 R2.
The domain contains two domain controllers.
The domain controllers are configured as shown in the following table.
DC1 hosts an Active Directory-integrated zone for contoso.com.
You add the DNS Server server role to DC2.
You discover that the contoso.com DNS zone fails to replicate to DC2.
You verify that the domain, schema, and configuration naming contexts replicate from DC1 to
DC2.
You need to ensure that DC2 replicates the contoso.com zone by using Active Directory
replication.
Which tool should you use?
A.
Dnslint
B.
A DNS Manager
C.
Active Directory Users and Computers
D.
Dnscmd
Explanation:
Note: If you see question about AD Replication, First preference is AD sites and services, then
Repadmin and then DNSLINT.
Think it’s D here :

Correct. There’s also a version of this where DNSCMD is replaced with ntdsutil and that becomes the right answer.
I think DNSCMD is most correct based on https://technet.microsoft.com/en-us/library/cc742490(WS.10).aspx You can use dnslint to troubleshoot replication issue https://support.microsoft.com/en-us/kb/321046
However if NTDSUTIL was an option I would choose it over dnslint based on the first linked article.
Here is a good one to explain that it is DNSCMD

answer is D
Answer is A because DnsLint is used at the command prompt to generate HTML reports. Read https://mcpmag.com/articles/2006/10/16/tools-to-monitor-dns.aspx
“DNS zone fails to replicate” so you have to diagnose problem
Except the question states that you need to “ensure that DC2 replications”
“DNSLint is a Microsoft Windows tool that can be used to help diagnose common DNS name resolution issues. It can be targeted to look for specific DNS record sets and ensure that they are consistent across multiple DNS servers. It can also be used to verify that DNS records used specifically for Active Directory replication are correct.”

DNSLint is diagnostic tool. You would be not able to fix anything with it. Couple or reports, that is all it can do. But we have been told: “need to ensure that DC2 replicates”, so I think that DNSCMD will be right answer if we have to pick ONE tool.
Dnscmd is a command-line interface for managing DNS servers. This utility is useful in scripting batch files to help automate routine DNS management tasks, or to perform simple unattended setup and configuration of new DNS servers on your network.
DNSLint has three functions that verify Domain Name System (DNS) records and generate an HTML report. The three functions are:
dnslint /d: This diagnoses potential causes of “lame delegation” and other related DNS problems.
dnslint /ql: This verifies a user-defined set of DNS records on multiple DNS servers.
dnslint /ad: This verifies DNS records specifically used for Active Directory replication.
You add the DNS role but does DNS automatically perform zone transfer? Anyone thought maybe in DNS manager there is more to configure before it can replicate?
