Preventive maintenance is crucial as it reduces system downtime by addressing potential issues before they escalate, ensuring that computer systems remain operational and efficient.

During a routine service, you discover a dusty CPU fan. What should you do to prevent overheating?

• Replace the CPU

• Clean the fan and heatsink

• Increase the power supply output

• Adjust the cooling settings

Answer explanation

Cleaning the fan and heatsink removes dust buildup, which improves airflow and cooling efficiency, preventing overheating. Other options do not directly address the issue of dust obstructing the cooling system.

A client's computer isn't booting. What is the first step you should take in diagnosing the issue?

• Replace the hard drive

• Check if the power cable is connected

• Reinstall the operating system

• Test the motherboard for faults

Answer explanation

The first step in diagnosing a computer that isn't booting is to check if the power cable is connected. This is a simple and common issue that can easily prevent the computer from powering on.

If a customer requests a more efficient computer system setup, what considerations should you prioritize?

• Installing a faster processor

• Reducing unnecessary applications and hardware

• Increasing storage capacity

• Ensuring compatibility and scalability

Answer explanation

Ensuring compatibility and scalability is crucial for a more efficient setup. It allows the system to adapt to future needs and integrates well with existing components, maximizing performance and longevity.

Which of the following is considered an input device?

• Monitor

• Printer

• Keyboard

• Speaker

Answer explanation

A keyboard is an input device used to enter data into a computer, while a monitor, printer, and speaker are output devices that display or produce information.

How does an operating system improve hardware performance?

• It adds extra physical resources

• It manages system resources efficiently

• It replaces outdated components

• It increases clock speed

Answer explanation

An operating system improves hardware performance by managing system resources efficiently. It allocates CPU time, memory, and I/O devices, ensuring optimal use and preventing bottlenecks, unlike simply adding resources or replacing components.

A client complains that their PC is running slow. Which hardware component should you examine first?

• RAM

• Power supply

• Keyboard

• Monitor

Answer explanation

RAM is crucial for system performance; insufficient RAM can cause slowdowns as the system struggles to manage tasks. Checking the RAM first helps identify if an upgrade or replacement is needed to improve speed.

A software installation failed on a client's PC due to insufficient permissions. What is the most likely cause?

• The hardware is incompatible

• The user does not have administrative rights

• The internet connection failed

• The operating system is corrupted

Answer explanation

The installation failed due to insufficient permissions, which typically means the user does not have administrative rights. Without these rights, the software cannot be installed properly.

Which hardware and software combination would you recommend to improve a graphic designer's workstation?

• More storage space and basic graphic design software

• High-end GPU and RAM with advanced graphic design software

• Basic CPU with a large SSD and basic graphic software

• Standard hardware with any software

Answer explanation

A high-end GPU and increased RAM are essential for graphic design tasks, enabling faster rendering and multitasking. Advanced graphic design software takes full advantage of this hardware, enhancing productivity and creativity.
