CompTIA A_ Certification All-In-One Exam Guide, Seventh Edition - Michael Meyers [88]
D. 128-bit data bus, two 128-KB L1 caches
5. When a tech adds a new Athlon 64 X2 processor to a motherboard, which of the following should the tech check? (Choose the best answer.)
A. Clock speed of the CPU, clock multiplier for the CPU
B. Clock speed of the CPU, clock multiplier for the CPU, voltage settings on the motherboard
C. Clock speed of the CPU, clock multiplier for the CPU, voltage settings on the motherboard, system clock speed
D. Voltage settings on the motherboard, system clock speed
6. The Intel Core Duo has which of the following advantages over the Pentium M?
A. Level 1 cache
B. 64-bit data bus
C. Quad pipelining
D. Dual processors
7. The Intel Core Duo processor has two 32-KB Level 1 caches, whereas the Athlon 64 X2 has one 128-KB Level 1 cache. What do caches provide for the processors?
A. They enable the CPU to continue working during pipeline stalls.
B. They enable the CPU to continue working during hard drive refreshes.
C. They enable the CPU to access RAM.
D. They enable the CPU to access the chipset memory controller.
8. What distinguishes the Athlon 64 from the original Athlon? (Select two.)
A. Athlon 64 uses an external memory controller.
B. Athlon 64 uses an internal memory controller.
C. Athlon 64 runs on a traditional frontside bus.
D. Athlon 64 runs on a HyperTransport.
9. Jane, the hardware technician for a nonprofit corporation, has 10 systems that she needs to upgrade with new microprocessors. Each system currently has a Socket 939 motherboard with an Athlon 64 3200+ CPU installed. To keep the upgrade costs low, her boss has told her to use the existing motherboards if possible.
Primary objective Upgrade the systems with faster CPUs.
Optional objectives Use existing motherboards and avoid adding any hardware aside from the CPU, fan, and heat-sink assembly.
Proposed solution Jane places an order for 10 PPGA Core 2 Duo processors and 10 PPGA to Socket 939 converters.
The proposed solution:
A. Meets only the primary objective
B. Meets the primary objective and one of the optional objectives
C. Meets the primary objective and both of the optional objectives
D. Meets none of the objectives
10. A donor gives five Socket 939 Athlon X2 processors to the nonprofit corporation for which Jane works as a technician. Jane has several systems with Socket 939 motherboards and Athlon 64 CPUs installed. Her boss wants her to upgrade five systems with the new processors, but to keep the upgrade costs low, if possible, by using the existing motherboards.
Primary objective Upgrade the systems with faster CPUs.
Optional objective Use existing motherboards.
Proposed solution Remove the Athlon 64 CPUs on five systems and replace them with the new Athlon 64 X2 CPUs. Update the motherboards, following the motherboard manufacturer’s guidelines.
The proposed solution:
A. Meets only the primary objective
B. Meets only the optional objective
C. Meets the primary and optional objectives
D. Meets neither objective
Answers
1. B. The CPU uses registers for temporary storage of internal commands and data.
2. C. The external data bus provides a channel for the flow of data and commands between the CPU and RAM.
3. A. The address bus enables the CPU to communicate with the memory controller chip.
4. C. The Core 2 Duo CPU has a 64-bit data bus and two 64-KB L1 caches.
5. C. Even with the CPUID built into modern processors, a good tech should check the motherboard settings for speed, clock multiple, and voltage and should also know the speed of the CPU.
6. D. The Intel Core Duo has dual processors, a definite advantage over the Pentium M.
7. A. Caches enable the CPU to continue working during pipeline stalls.
8. B, D. The Athlon 64 used an internal memory controller and ran on HyperTransport.
9. D. What was Jane thinking? You can’t install Intel processors on AMD-based motherboards. Her proposed solution accomplishes none of the objectives.
