Explanation
If a technician is tasked with upgrading a laptop's RAM, the technician should verify the memory requirements of the motherboard first. The motherboard of the laptop will have specific requirements for the type and amount of RAM that can be installed. By verifying the memory requirements of the motherboard, the technician can ensure that the new RAM is compatible with the laptop.
Before upgrading a laptop's RAM, a technician should verify the memory requirements of the motherboard to ensure the new RAM is compatible. The type, speed, and maximum capacity of the RAM should be checked to ensure it meets the requirements of the motherboard. References: CompTIA A+ Certification Exam Guide, pg. 347-348

The most likely explanation for the distorted image on the projector is that the projector's aspect ratio is set incorrectly. The aspect ratio is the ratio of the width to the height of the image, and it affects how the image is displayed on the screen. If the aspect ratio of the projector does not match the aspect ratio of the laptop, the image may appear stretched, squashed, cropped, or letterboxed.
To fix the distorted image, the technician should follow these steps:
* Check the aspect ratio of the laptop and the projector. The aspect ratio of the laptop can be found in the display settings of the operating system, such as Windows or Mac OS. The aspect ratio of the projector can be found in the user manual or the on-screen menu of the projector. Common aspect ratios are 4:3,
16:9, and 16:10.
* Adjust the aspect ratio of the projector to match the aspect ratio of the laptop. The technician can use the remote control or the buttons on the projector to access the on-screen menu and select the appropriate aspect ratio option. Some projectors may have a dedicated aspect ratio button on the remote control or the projector itself.
* Verify that the image is displayed correctly on the screen. The technician can use the zoom, focus, or keystone buttons on the projector or the remote control to fine-tune the image quality and alignment.

Explanation
This is because a docking station can connect multiple monitors to a laptop without using USB ports, which are disabled in this scenario. A splitter cable would only allow two monitors to be connected, not three. A discrete graphics card would require opening the laptop and installing hardware, which may not be feasible or allowed in a high-security environment. An HDMI switch would only allow one monitor to be active at a time, not all three simultaneously.

802.11 ax is a wireless networking protocol that utilizes the 5.0GHz frequency and has the best speed and reception among the options given. 802.11 ax offers higher data rates, lower latency, increased capacity, and improved power efficiency than previous protocols. It is also known as Wi-Fi 6 or High Efficiency Wireless (HEW). 802.11a also uses the 5.0GHz frequency, but it is an older protocol that has lower speed and reception than 802.11 ax. 802.11b/g/n use the 2.4GHz frequency, which is more crowded and prone to interference than the 5.0GHz frequency. 802.11n can use both frequencies, but it is also slower and less efficient than 802.11 ax.
