B. Correct the keystone:

A keystone correction adjusts the image shape when a projector is angled either up or down. When a projector is not positioned directly perpendicular to the screen, the image becomes distorted or offset. Correcting the keystone will resolve alignment issues, ensuring that the presentation matches the display.

Incorrect Options:

A. Adjust the color settings: This is used for improving color balance and has no impact on ghosting or mismatched images.

C. Increase the brightness levels: Brightness changes the visibility of the image but does not address ghosting or alignment.

D. Replace the monitor: Replacing the monitor is unnecessary unless there is hardware failure, which is not indicated here.

Key Takeaway: Keystone correction is essential to resolve alignment and distortion issues in projected images.

The ATX 3.0 16-pin connector provides power to high-end graphics cards, and a poor connection could lead to power issues and burning smells.

Comprehensive and Detailed In-Depth Explanation:

USB-C is a versatile connector capable of transmitting data, video, audio, and power. With standards like DisplayPort over USB-C or Thunderbolt 3/4, it can be used for external displays, file transfers, charging, and more — all through one cable.

Option B (HDMI): Supports video and audio but not general data transfer.

Option C (DisplayPort): Similar to HDMI — supports video/audio but not general file transfer.

Option D (VGA): Legacy analog video only — no data or audio support.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.1: Identify common connector types.

The two sets of colors on the motherboard indicate that it supports dual-channel memory, which doubles the bandwidth available to the memory controller. Dual-channel memory requires two identical memory modules to be installed in pairs in the correct slots to work effectively. In this case, the user can install two identical RAM modules to enable dual-channel memory, which will provide better performance when using multimedia applications that consume a lot of memory.

The technician should check the MAC filtering list next as the new router may have a different MAC address than the old router. References: CompTIA A+ Certification Exam Guide, Exam 220-1001, Page 332

Firmware is a type of software that controls the hardware components of a device, such as the motherboard, hard drive, or keyboard. Firmware updates can improve the performance, stability, and compatibility of the device, as well as fix bugs and security issues. Running a firmware update can help to resolve the issue of a slow laptop, especially if the firmware is outdated or corrupted.

The best option that the technician should choose for the best performance is A. PCIe SSD connected via NVMe interface. This option means that the technician should install a solid state drive (SSD) that uses the PCIe (Peripheral Component Interconnect Express) bus and the NVMe (Non-Volatile Memory Express) protocol to communicate with the motherboard. This option can offer the following advantages:

Faster speed: PCIe SSDs can transfer data faster than SATA or IDE SSDs, as they use more lanes and have higher bandwidth. PCIe SSDs can reach speeds of up to 7,000 MB/s, while SATA SSDs are limited to 600 MB/s and IDE SSDs are even slower12. NVMe is a protocol that is designed specifically for SSDs and can optimize their performance by reducing latency and increasing parallelism3.

Smaller size: PCIe SSDs can be smaller than SATA or IDE SSDs, as they do not require additional cables or connectors. PCIe SSDs can come in different form factors, such as M.2 or U.2, which can fit in different slots on the motherboard12.

Higher reliability: PCIe SSDs can be more reliable than SATA or IDE SSDs, as they have less moving parts and are less prone to mechanical failures or data corruption. PCIe SSDs can also support features such as error correction and wear leveling, which can enhance their durability and lifespan12.

If you want to install Windows 11 on a virtual machine using Hyper-V, you will have to use a “Generation 2” VM and enable the “trusted platform module” (TPM) and Secure Boot options. Otherwise, the OS won’t install.

Starting with Windows 11, Microsoft is changing the system requirement and making TPM 2.0 and Secure Boot a prerequisite to perform an in-place upgrade or clean install the new version on any device. This is in addition to the new 4GB of RAM and at least 64GB of storage.

Furthermore, Multithreading is not a requirement for hyper-v hosting.

To create virtual machines on a workstation, the technician needs to enable Trusted Platform Module (TPM) in the system BIOS. TPM is a hardware-based security feature that helps protect the system from unauthorized access and tampering. It is required for many virtualization technologies, including Hyper-V, VirtualBox, and VMware.
