You have a domain controller named Server1 that runs Windows Server 2012 R2 and has
the DNS Server server role installed. Server1 hosts a DNS zone named contoso.com and a
GlobalNames zone.
You discover that the root hints were removed from Server1.
You need to view the default root hints of Server1.
What should you do?

A.
From Event Viewer, open the DNS Manager log.

B.
From Notepad, open the Cache.dns file.

C.
From nslookup, run root Server1.contoso.com.

D.
From Windows Powershell, run Get-DNSServerDiagnostics

Explanation:
DNS Server service implements root hints using a file, Cache.dns, stored in the
systemroot\System32\Dns folder on the server. Thus viewing the Cache.dns file will show
the root hints.
