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.
Which file should you open?

A.
Netlogon.dns

B.
Cache.dns

C.
Globalnames.dns

D.
Place.dns

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.
