14. Users are complaining about slow network performance. Using Network Monitor, youhave identified the source of the excessive traffic is inbound and outbound traffic fromyour DNS server. How would you identify the source of the excessive DNS traffic?A. Using the host IP addresses from Network Monitor, perform a tracert command toeach host and determine the time it takes to get to each requested destination.B. Use System Monitor to watch performance counters on the DNS server and identifythe cause of the slow performance.C. Use System Monitor to watch performance counters on the client machines to iden-tify the machine that is using the DNS server heavily.D. Ping the DNS server using the –t option from different host machines to identify thesubnet that is causing the increase in network traffic.B. Using System Monitor, you can identify the problem areas and zero in on the exactoperations in DNS that are causing the traffic.A, C, D. Using Tracert is incorrect because it provides information only on routinglatency and does not address the issue you have identified with the DNS server. SystemMonitor running on the client machine may provide some insight related to eachclient, but the source of the network utilization problem has been identified as theDNS server. Ping –t would only serve to increase the network load and would do socontinuously.
