Operating Systems (OS) are fundamental software that manage computer hardware and provide services for computer programs. They act as an intermediary between users and hardware, facilitating interaction with the computer system. In CompTIA A+, understanding operating systems is essential as they'r…

Question 1

Which of the following is a key function of the Windows Process Explorer tool?

Correct Answer: Displaying real-time system information

The correct answer is 'Displaying real-time system information.'

Windows Process Explorer is an advanced system monitoring tool that provides detailed, real-time information about running processes, system resource usage, and other performance metrics. It offers a more in-depth view of system activities compared to the standard Task Manager.

Key features of Process Explorer include:
1. Detailed process information
2. Real-time CPU, memory, and I/O usage graphs
3. Ability to identify and kill malicious processes
4. Viewing and managing process dependencies

The other options are incorrect because:

'Optimizing hard disk performance through defragmentation' is typically performed by the Disk Defragmenter tool, not Process Explorer.

'Creating system restore points for backup purposes' is a function of the System Restore feature in Windows, not Process Explorer.

'Managing user accounts and access permissions' is handled by the User Account Control (UAC) and other built-in Windows administrative tools, not Process Explorer.

Process Explorer's primary function is to provide advanced, real-time system information and process management capabilities, making it an essential tool for system administrators and power users.

Question 2

A graphic designer experiences slow performance when working with large image files. Which hardware component upgrade will provide the most improvement?

Correct Answer: Add more RAM

Adding more RAM will provide the most improvement for a graphic designer working with large image files. When working with large files, the computer needs to load them into memory (RAM) for processing. If there is insufficient RAM, the system will rely on virtual memory, which uses the slower hard drive, causing performance to suffer. More RAM allows the computer to hold more of the image file data in fast memory, improving overall performance. Replacing the hard drive with a larger one would provide more storage space but not necessarily improve performance. Upgrading the CPU or graphics card could offer some benefits but would have less impact compared to adding RAM when the primary issue is handling large image files.

Question 3

A technician needs to restore a file from a cloud backup. What action should the technician take?

Correct Answer: Download the selected file from the cloud backup provider

To restore a specific file, the technician should download the selected file from the cloud backup provider. Restoring the entire backup or copying files from other sources is not necessary.
