Exam Tips - Chapitre 3

Relis d'abord ces points que le livre lui-meme signale comme importants pour l'examen ("A+ Certification Exam Tips"). Puis reponds au QCM pour verifier que tu as vraiment compris de quoi il s'agit - pas juste memorise les mots.

Q1. What is a 'multisocket' motherboard, and where is it typically found?

A motherboard with multiple CPU sockets, typically found in servers. A motherboard with multiple RAM slots, typically found in laptops. A motherboard with multiple PCIe x16 slots, typically found in gaming PCs. A motherboard with multiple power connectors, typically found in tablets.

Q2. Which statement about server and mobile device motherboards is correct, per the exam tips?

They are almost always generic and interchangeable between brands. They are frequently proprietary items, tied to their specific manufacturer. They never use CPU sockets at all. They cannot have expansion slots.

Q3. Which processor architecture is associated with RISC design and is widely used in mobile devices for its power efficiency?

x86 x64 ARM AGP

Q4. What must be true about a CPU's firmware setting before virtual machines can run efficiently on that computer?

The CPU must run at over 6 GHz. Virtualization support must be enabled in the firmware (BIOS/UEFI). The motherboard must be multisocket. The CPU must use only a single core.

Q5. A motherboard's manual lists a slot as "x16 (x4 mode)." What does this actually mean for that slot?

It physically accepts an x16-sized card but only transmits using 4 lanes (x4 speed). It only physically accepts x4-sized cards. It runs faster than a true x16 slot. It cannot accept any PCIe card at all.

Q6. Can a PCIe x16 video card be installed into a motherboard's physical x4 slot?

Yes, it always fits and runs at full x16 speed. No - a larger card cannot physically fit into a lower-numbered (smaller) slot. Yes, but only if the card is an AGP adapter. Only if the motherboard is multisocket.

Q7. A customer has an AMD Ryzen 9 processor and a motherboard with only an Intel LGA 1700 socket. What happens if they try to install it?

It works fine after a BIOS/UEFI update. It won't fit - AMD and Intel processors each require their own matching socket type. It works, but runs slower than expected. Only the CPU cooler needs to be swapped for it to fit.

Q8. Thermal paste has hardened over time, sticking the heat sink firmly to the CPU. What is the correct way to separate them?

Pry them apart with a flat screwdriver. Use a thermal paste cleaner, acetone, or denatured alcohol to loosen the bond. Heat the CPU with a hair dryer and pull hard. Soak the whole motherboard in water.

Q9. Which TWO of the following are CPU cooling methods named in the exam tips?

Heat sink Liquid cooling Overclocking Capacitor swelling

Q10. Before applying power to a newly built computer for the first time, what absolutely must already be installed?

Just the CPU - cooling can be added afterward. The CPU AND its heat sink/fan/cooling unit - running it uncooled can destroy or weaken it. Only a case fan is required. Nothing extra, as long as the room is air-conditioned.

Q11. Which motherboard form factor is smaller: microATX or ITX?

microATX ITX They are the same size. ATX

Q12. What is a practical downside of a computer case that requires a proprietary motherboard?

It will never physically fit any CPU. A replacement motherboard must come from the original manufacturer, usually at a higher cost. It can no longer use any expansion slots. The form factor no longer needs to be checked.

Q13. What is the main difference in form between a TPM and an HSM, as typically implemented?

A TPM is usually built into (or has a dedicated slot on) the motherboard, while an HSM is commonly a separate adapter.
