What are the ...
... four steps in the process of analyzing and interpreting performance-
monitoring results?
The four steps are (1) establish a baseline, (2) analyze free CompTIA practice tests performance-monitoring results, (3) plan and implement changes to meet the baseline, and (4) repeat steps 2 and 3 until performance is optimized.
5.In the process of analyzing and interpreting performance-monitoring results, what is a baseline?
A baseline is a measurement derived from the collection of data over an extended period during varying workloads and user connections, representing acceptable performance under typical operating conditions. The baseline indicates how system resources are used during periods of normal activity and makes it easier to spot problems when they occur.
Margie tells you that she wants to install new firewalls between all of the Active
Directory sites that she has worldwide. She remembers that the original installers
had to do something special to the firewalls because they were being used with
Active Directory. She cannot remember what that special something was, so she
asks if you know of anything. What would you tell her?
If you need Active Directory replication to occur between domain controllers of the same domain, you must allow a Remote Procedure Call (RPC) connection to occur through the fire?wall. You can do this by opening the RPC Endpoint mapper (TCP 135) and also allowing the dynamic RPC ports of 1024-65535. Alternately, you can configure the domain controllers to use different RPC ports.
6.Margie wants you to determine whether the existing domain controllers are using default or custom ports for replication. How could you determine this?
You could use Network Monitor (or another network packet capturing utility) to analyze the traffic on your network to determine which ports are being used for RPC and NTFRS traffic. You can also check the firewall logs or monitor the firewall to see what type of traffic is coming and going right now. Another method is to review the configuration of the domain Free A+ practice exams controllers registry for the NTFRS service and RPC ports.
