3.4 Given a scenario, install and configure motherboards, central processing units (CPUs), and add-on cards

The correct answer is C. NVMe SSDs require a specific NVMe-compatible motherboard with an M.2 slot. All other options are incorrect.

The correct answer is B. x86 architecture, also known as 32-bit processors, has a maximum addressable memory limit of 4 GB. 2 GB is incorrect as it underestimates the maximum RAM capacity. x64 architecture, also known as 64-bit processors can address memory higher than 4 GB.

The correct answer is A. In the BIOS settings, ensure that the desired operating system is set as the first boot option. All other options are incorrect as they are unrelated to boot option troubleshooting.

The correct answer is D. Heat sinks and fans are essential components in desktop computers to dissipate heat generated by the CPU. As the CPU performs computations, it generates heat, and if not properly managed, it can lead to overheating. Heat sinks are designed to absorb and disperse the heat away from the CPU, while fans provide airflow to carry the heat away from the heat sink. Heat sinks and fans do not focus on power consumption, speed of data transfer, or EMI.

The correct answer is A. The ITX form factor is commonly chosen when building a compact and portable gaming PC. The small size of ITX motherboards allows for a more compact system build, making it easier to transport and suitable for LAN parties or gaming on the go. Other options are not ideal scenarios for using an ITX form factor. They typically require motherboards with more expansion slots and connectivity options.

The correct answer is A. The primary advantage of liquid cooling over air cooling is improved thermal efficiency. Liquid cooling systems, such as all-in-one (AIO) coolers or custom loops, are designed to effectively dissipate heat from the components, resulting in lower temperatures compared to air cooling. This enhanced thermal efficiency allows for better overclocking potential and overall improved performance of the system. All other options are incorrect.

The correct answer is C. Performing a TPM reset clears the previous encryption key stored in the TPM and establishes a fresh secure connection with the upgraded hardware, allowing the system to boot and regain access to the stored data. Disabling the TPM functionality in the BIOS may prevent the system from accessing the encrypted key required to decrypt the data. Reverting to the previous hardware configuration might not be practical or necessary, and it does not address the issue of the TPM encryption key.

The correct answer is A. A clicking noise during computer bootup may indicate a failing hard drive with mechanical issues such as a malfunctioning read/write head or a failing spindle motor. Promptly backing up the data and replacing the failing hard drive is crucial to prevent data loss. An overheating CPU can cause the computer to shut down. A loose power cable might result in power loss. A malfunctioning graphics card is not related to a clicking noise.

The correct answer is A. The 8-pin EPS connector is commonly used to provide dedicated power to the CPU on a desktop motherboard.
