NEW QUESTION # 181
A technician is replacing the motherboard of a workstation for a user who runs multiple large applications at the same time. Which of the following motherboard specifications would provide the most significant improvement in performance?
- A. Number of DIMM slots
- B. Number of USB ports
- C. Number of PCI slots
- D. Number of HDMI ports
Answer: A
Explanation:
Explanation
The correct answer is A. Number of DIMM slots.
The number of DIMM slots on a motherboard determines how much RAM can be installed on the system.
RAM is a crucial component for running multiple large applications at the same time, as it allows the CPU to access data faster and avoid swapping to the hard drive. Having more DIMM slots means that more RAM can be added, which can improve the performance and responsiveness of the system.
B: Number of HDMI ports. This is not a correct answer. The number of HDMI ports on a motherboard determines how many monitors can be connected to the system. HDMI ports are used for video and audio output, but they do not affect the performance of the system when running multiple large applications.
C: Number of PCI slots. This is not a correct answer. The number of PCI slots on a motherboard determines how many expansion cards can be installed on the system. PCI slots are used for adding devices such as sound cards, network cards, or graphics cards, but they do not affect the performance of the system when running multiple large applications.
D: Number of USB ports. This is not a correct answer. The number of USB ports on a motherboard determines how many peripherals can be connected to the system. USB ports are used for connecting devices such as keyboards, mice, printers, or external drives, but they do not affect the performance of the system when running multiple large applications.

- A. NVMe SSD
- B. 15,000rpm SAS
- C. 5,400rpm HOD
- D. SCSI RAID
Answer: C
Explanation:
Explanation
The correct answer is D. 5,400rpm HDD.
A 5,400rpm HDD (Hard Disk Drive) is a type of storage device that uses spinning magnetic disks to store data. A 5,400rpm HDD is the least expensive per gigabyte among the options given, as it has a lower rotational speed and performance than other types of HDDs or SSDs (Solid State Drives). A 5,400rpm HDD is suitable for archiving a large number of photos that are not accessed frequently, as it can offer high capacity and reliability at a low cost.
the average cost per gigabyte of a 5,400rpm HDD is around $0.02 to $0.0312, while the average cost per gigabyte of the other options are:
NVMe SSD: $0.10 to $0.1534
SCSI RAID: $0.20 to $0.305
15,000rpm SAS: $0.30 to $0.40
Therefore, a 5,400rpm HDD is the cheapest option among the four.

The technician then connects a test laptop to the router via the user's Cat 5 cable and records the following information:
Which of the following is MOST likely causing the user's issue?
- A. Misconfigured default gateway
- B. Faulty NIC
- C. Incorrect IP address
- D. Bad network cable
Answer: B
Explanation:
Explanation
Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.
