If a server is experiencing high CPU utilization, which diagnostic tool can be used to identify the processes consuming the most CPU resources?

Both Task Manager and Resource Monitor are standard Windows utilities designed for real-time monitoring of system resources. Task Manager provides a direct and easily accessible list of running processes that can be sorted by CPU utilization to quickly identify the highest consumers. Resource Monitor offers a more granular view, displaying detailed CPU usage not only by process but also by associated services and handles, making it another powerful and correct tool for this diagnostic task. Both tools directly fulfill the requirement of identifying processes consuming the most CPU resources.

C. Event Viewer: This tool is used for browsing historical system, application, and security logs. It does not provide real-time data on process-specific CPU consumption.
D. Performance Monitor: This tool is primarily for collecting and analyzing performance counter data over extended periods, which is more suited for trend analysis than for immediate, real-time process identification.

1. Microsoft Corporation. (2023). Task Manager. Microsoft Learn.

Reference: In the "Processes tab" section, it states, "The Processes tab in Task Manager shows you the apps and background processes that are running on your system... To sort the list, select one of the column headers. For example, select the CPU header to sort the list by CPU usage..." This directly supports using Task Manager to identify processes by CPU consumption.

2. Microsoft Corporation. (2023). Use Resource Monitor to check for issues. Microsoft Learn.

Reference: The overview states, "Resource Monitor displays per-process and aggregate CPU, memory, disk, and network usage information... The CPU tab displays the processes and services, and the CPU usage." This confirms Resource Monitor's capability for this task.

3. Microsoft Corporation. (2023). Using Performance Monitor. Microsoft Learn.

Reference: The documentation describes its function: "...you can monitor application and hardware performance in real time, customize what data you want to collect in logs, define alerts... and view past performance data." This highlights its focus on logging and long-term analysis rather than immediate process identification.

4. Microsoft Corporation. (2023). Event Viewer. Microsoft Learn.

Reference: The documentation states, "Event Viewer is a tool that displays detailed information about significant events (for example, programs that don't start as expected or updates that are downloaded automatically) on your computer." This confirms its role as a log analysis tool.
