Your network contains two DNS servers named DNS1 and DNS2 that run Windows Server 2012
R2. DNS1 has a primary zone named contoso.com. DNS2 has a secondary copy of the
contoso.com zone.
You need to log the zone transfer packets sent between DNS1 and DNS2.
What should you configure?

A.
Monitoring from DNS Manager

B.
Logging from Windows Firewall with Advanced Security

C.
A Data Collector Set (DCS) from Performance Monitor

D.
Debug logging from DNS Manager

Explanation:
Debug logging allows you to log the packets sent and received by a DNS server. Debug logging
is disabled by default, and because it is resource intensive, you should only activate it temporarily
when you need more specific detailed information about server performance.
