A technician is upgrading RAM in a desktop. Which step is most important to perform BEFORE purchasing new RAM modules?

Disconnect all power cables from the motherboard

Check the motherboard's maximum supported memory capacity

Remove the existing RAM modules

Update the BIOS to the latest version

A technician is upgrading a desktop PC to add Wi-Fi 6 capability. The motherboard has one free PCIe x1 slot, one free M.2 slot that supports both SATA and PCIe, and no built-in Wi-Fi. The user wants the fastest possible wireless speed. What should the technician install?

An M.2 SATA Wi-Fi card, since the slot supports SATA.

A USB Wi-Fi 6 adapter plugged into a USB 3.0 port.

A PCIe x1 Wi-Fi 6 card with external antennas.

An M.2 Wi-Fi 6 card that uses the PCIe interface, with antennas attached to the card's connectors.

A user wants to upgrade their desktop PC from 8 GB to 16 GB of RAM. The PC currently has one 8 GB DDR4-2400 module. The user buys a single 8 GB DDR4-3200 module. After installing it, the system boots but shows only 8 GB in Task Manager. What should you do?

Update the motherboard BIOS to support DDR4-3200.

Enable XMP in the BIOS to run the new module at its rated speed.

Return the new module and buy a matched pair.

Check that the new module is fully seated in the slot.

When installing a RAM module, what is the correct way to ensure proper seating?

Insert the module at a 45-degree angle and then rotate it upright

Insert the module with the notch facing the wrong way and then flip it

Press down firmly on the module until the retention clips snap into place

Use excessive force to push the module in, even if the notch is misaligned
