A video production workstation that will consist of two high-end GPUs will require a lot of power and a modular power supply. A modular power supply allows the technician to connect only the cables that are needed for the components, which reduces clutter and improves airflow. A 1,200W power supply should be enough to power the two GPUs and other components, but the exact wattage depends on the specifications of the GPUs and other components. A 400W external power supply is not enough to power the workstation and may not be compatible with the ATX case. Two 600W redundant power supplies are unnecessary and may not fit in the ATX case. A 1,500W uninterruptible power supply (UPS) is a device that provides backup power in case of a power outage, but it is not a replacement for a power supply unit (PSU). References:

DisplayPort is a type of external monitor connection that provides the highest possible resolution for a PC. DisplayPort supports up to 8K resolution at 60 Hz, or 4K resolution at 120 Hz, with a maximum bandwidth of 32.4 Gbps. DisplayPort also supports audio, multiple monitors, and adaptive sync. DisplayPort is compatible with other types of connections, such as HDMI and DVI, with adapters.

The correct answer is A. Turn on the laptop and move it again to replicate the issue.

One of the basic troubleshooting techniques is to reproduce the problem and observe the symptoms. This can help to identify the cause and the solution of the issue. By turning on the laptop and moving it again, the technician can verify if the noise is related to the laptop’s movement, and if it affects the laptop’s performance or stability. The noise could indicate a loose or damaged component, such as a fan, a hard drive, or a cable, that needs to be fixed or replaced.

The other options are not the best next steps, because they do not confirm the source of the problem, and they may cause more damage or complications. Reseating the memory modules and the SSD (option B) may be helpful if the laptop has booting or performance issues, but it is unlikely to solve the noise problem. Removing the internal battery and looking for loose parts (option C) may be risky if the technician does not follow proper safety precautions, such as disconnecting the power cord and wearing an anti-static wrist strap. Inspecting the connections for a damaged cable (option D) may be part of the troubleshooting process, but it should be done after replicating the issue and narrowing down the possible causes.

The screen needs to be recalibrated. The cursor drift is a common symptom of a misaligned touch screen, which can be caused by physical shocks, temperature changes, or software updates. The screen can be recalibrated using the tablet’s settings or a utility program. The screen is not physically damaged, as there is no visible crack or break. The screen rotation is not related to the cursor drift, as it only affects the orientation of the display. The touch-pen battery is not relevant, as the cursor drift occurs even without using the pen.
