A clever manager has realized that most components are fine, but upgrading the RAM will make a significant impact, and users will be happier. They also want to give the appearance that they bought completely new desktops, so they will buy new cases with the memory upgrade. Which of the following cases should they purchase? ATX mATX SFF ITX

ATX The advanced technology extended (ATX) specification is the standard form factor for most desktop PC motherboards and cases. Full-size ATX boards are 12 inches wide by 9.6 inches deep (or 305 mm x 244 mm).

A curious IT professional is exploring how AMD and Intel graphics cards operate. They are conducting a basic test for the frame rate it can produce for a particular game or application. Which part of the graphics card is the IT professional testing? Memory GPU Video port Hardware security module (HSM)

GPU The graphics processing unit (GPU) is a microprocessor designed and optimized for processing instructions that render 2-D and 3-D images and effects on-screen.

A PC technician is helping out a nonprofit organization who has older laptops. They want to implement data at rest encryption, but the laptops are older and do not support a trusted platform module (TPM). What should the technician use? Boot password UEFI HSM PGA

HSM A secure USB key or thumb drive used to store cryptographic material can be a hardware security module (HSM), which is useful if the computer does not support TPM.

A server technician sets up a small server at home to keep up with emerging technology and to learn in a test environment at home. However, the technician wants a low power consumption to use a small form factor. Also, since the technician is building it from scratch, what type of motherboard should the technician get? ITX ATX mATX CompactFlash

ITX Small form factor (SFF) PCs are popular as home machines and mini servers. SFF PCs often use Via's Mini-ITX (Information Technology Extended) form factor.

A computer operator has an x8 PCIe but plugs it into an x16 connector. The operator notices that performance seems to be a bit sluggish. What is the most likely cause? It defaulted to a slower speed because of the mismatch. The RAM does not match. It is only working at x1. It is working fine.

It is only working at x1. An x8 card will fit in an x8 or x16 socket. Therefore, the card should work at x8, but in some circumstances, it may only work at x1.

A PC technician is diagnosing a faulty laptop and finds that the memory has likely gone bad, so the technician opens the case to try and replace it. However, the technician gets sidetracked when noticing that the SSD is provisioned in an adapter card form factor. What format is this most likely in? SATA eSATA M.2 SAN

M.2 A technician can provision a solid-state drive (SSD) in an adapter card form factor. These often use an M.2 interface. As well, an M.2 port orients horizontally.

A user accidentally entered the Unified Extensible Firmware Interface (UEFI) setup program. How can the user generally get out? Escape F10 F2 Mouse

Mouse UEFI setup programs use a graphical interface and have mouse support, though advanced menus may still require keyboard navigation.

A server administrator often downloads large files onto the desktop provisioned as virtual machines. The administrator often waits for hours, even though there is a physical connection to the internet. The company's internet should be able to handle significantly faster downloads. What component should the administrator upgrade to increase their download? Hard drive Memory NIC Capture card

NIC A dedicated network interface card (NIC) may also provide multiple ports. The administrator can bond these into a single higher bandwidth link.

A server engineer replaces the company's gold standard image quarterly, which they use to provision virtual machines. The engineer often has to wait for hours for the gold images to download since the company has several operating systems to maintain. The engineer checks with the networking department and confirms that internet speed, routing, and switching are not the holdup. What component can the engineer replace on their endpoint to help? Hard drive Memory Capture card NIC

NIC A dedicated network interface card (NIC) may also provide multiple ports. The engineer can bond these into a single higher bandwidth link.
