When a technician finds that a user's office is not listed for an upgrade but the user has submitted a request, the appropriate action is to:

Notify the project manager about the user's concern: The project manager oversees the upgrade process and can address any discrepancies or omissions in the upgrade list.

Ask the company's human resources department to address the issue: HR typically handles personnel matters, not hardware upgrades.

Tell the user that this request is not on the list to be upgraded: This does not resolve the user's concern and could cause frustration.

Ask the user's supervisor if the technician should upgrade the computer: The supervisor may not have the authority or information to make decisions about the upgrade list.

Restarting services can resolve issues with web applications without requiring a full server reboot, which aligns with the company policy.

Restart services: Likely to resolve issues with the web application by refreshing the necessary services.

Roll back Windows updates: Unnecessary if the issue is with the application services.

Perform a Windows repair: More disruptive and not typically needed for application service issues.

Add RAM to the server: Would require a reboot and is not immediately necessary for troubleshooting application issues.

The most likely reason for the installation failure of a 64-bit software is that the operating system is incompatible, specifically if the system is running a 32-bit version of the OS. A 64-bit program requires a 64-bit operating system to run, and if the user’s OS is a 32-bit version, the software will fail to install. Other reasons, like needing administrator privileges or updating .NET, are valid but less likely since the error message would be different.

When a system administrator discovers a user's PC running slowly with 100% CPU utilization, it often indicates that the system is being used for unauthorized purposes, such as being part of a botnet attack. Here’s why:

Botnet attack: Botnets are networks of computers infected with malware and controlled by an attacker. These infected computers (bots) are often used to carry out tasks like sending spam or participating in Distributed Denial of Service (DDoS) attacks. The high CPU utilization and resource usage indicate that the computer might be performing tasks dictated by the botnet controller.

Firewall activities: While firewall activities can use some resources, they generally do not cause sustained high CPU utilization.

DDoS attack: DDoS attacks target external systems by overwhelming them with traffic. A system participating in a DDoS might have high network usage, but the primary symptom on the user’s PC would be high network activity, not necessarily CPU usage.

Keylogger attack: Keyloggers record keystrokes and generally do not cause high CPU utilization. They are more stealthy and have minimal resource footprints.
