Chad is the network administrator for a network that consists of a single Active Directory domain named Globe.com. A Windows Server 2003 computer named S1 is the only DNS server in the domain. It hosts no other zones. Users report that connecting to computers within the Globe.com domain is slow. What should Chad do to check if DNS client traffic on S1 is causing this problem?
  1. Use System Monitor to create a log of the Network Interface counter Total bytes/sec.
  2. Use System Monitor to create a log of the DNS counters Dynamic updates/see and Total queries/sec.
  3. Enable debug logging on S1. Configure the log to capture Notification events.
  4. Enable debug logging on S1. Configure the log to capture Update events.
Explanation
Answer - B - To check if DNS client traffic on S1 is causing this problem, Chad should use System Monitor to create a log of the DNS counters Dynamic updates/see and Total queries/sec.

Key Takeaway: DNS server performance counters can be used to measure and monitor server activity aspects such as: Number of overall queries and responses processed by a DNS server; UDP or TCP counters, for measuring DNS queries and responses that are processed using these protocols; Dynamic update and secure dynamic update counters; Memory usage counters, for measuring system memory usage and memory allocation patterns; Recursive lookup counters, for measuring queries and responses when the DNS Server service uses recursion to look up and fully resolve DNS names on behalf of requesting clients; WINS lookup counters; and Zone transfer counters.
