CompTIA Updated 220-1101 Exam Questions and Answers by yasir

Physical cabling issues are the most likely cause of the display problems described. Loose, damaged, or faulty cables can cause intermittent signal loss, leading to a slow response, color distortion, lines on the display, and intermittent blanking. Checking and securing the connections or replacing the cable can resolve these issues. This aligns with the troubleshooting steps outlined in the CompTIA A+ Core 1 (220-1101) Exam Objectives under section 4.0 "Virtualization and Cloud Computing" and 5.0 "Hardware and Network Troubleshooting", which include checking physical connections as a primary step in diagnosing display issues .

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.

The best way to complete the upgrade with the least amount of downtime is to clone the HDD to the SSD using cloning software, and then replace the HDD with the SSD. This way, the user does not have to reinstall the operating system and applications, or copy over their data manually. The other options would either take more time or result in data loss or inaccessibility. Verified References: [How to Upgrade Your Laptop’s Hard Drive to an SSD].

A limited wireless range after replacing the wireless card could indicate that the antenna is not properly connected to the card, or that the antenna is damaged or obstructed. According to the web search results, some possible steps to troubleshoot and verify the antenna’s connection are:

Open the laptop case and locate the wireless card and the antenna wires. Make sure that the wires are securely attached to the card’s connectors, and that they are not loose or broken12.

Check the position and orientation of the antenna. Make sure that it is not blocked by any metal objects, walls, or other sources of interference. Adjust the angle or location of the antenna if possible to improve the signal strength3.

Replace the antenna with a new one or a compatible one from another device. Test the wireless range and performance with the new antenna2.
