A customer asks you over the phone how much it will cost to upgrade memory on her desktop system to 16 GB. She is capable Windows user and to access BIOS/UEFI setup using the user power-on password you set up for her. Which actions can you ask the customer to perform as you direct her over the phone to get the information you need to develop an estimate of the upgrade's cost?

• Use BIOS/UEFI to view how much memory to installed and how much memory the system can hold.

• Enter info.32.exe to determine how much memory is currently installed.

• Use BIOS/UEFI to show which memory slots are used and how much memory is installed in each lists.

• View the system Information window to determine how much memory is currently installed.

The GeForce GTX 1060 graphics card requires 120 W of power. You plan to install it in a PCIe 3.0 x16 slot. Will you need to also install extra power to the card? If so, how can you do that?

• Yes. The PCIe 3.0 x16 slot provides 75 W and you need to connect the card using a PCIe 8-pin connector to gain additional power.

• No. The PCIe 3.0 x16 slot provides all the necessary power and no extra power connection is required.

• Yes. The PCIe 3.0 x16 slot provides 75 W and you need to connect the card using a PCIe 6-pin connector to gain additional power.

• Yes, The PCIe 3.0 x16 slot provides 100 W and you need to connect the card using a Molex connector to gain an additional 20 W.
