ECC stands for Error Correction Code, which is a type of memory that can detect and correct data errors that may occur during processing or transmission. ECC memory is commonly used in servers that handle sensitive or critical information, such as payment information online, because it can reduce the risk of data corruption, system crashes, or security breaches12.
DDR4 is a generation of DDR technology, which stands for Double Data Rate. DDR4 memory is faster and more power-efficient than its predecessors, but it does not necessarily have ECC functionality. DDR4 memory can be either ECC or non-ECC1.
VRAM is Video RAM, which is a type of memory that is dedicated to storing graphics data for display.
VRAM is usually found on graphics cards or integrated graphics processors, not on servers3.
SODIMM is Small Outline DIMM, which is a type of memory module that has a smaller size and lower profile than regular DIMMs. SODIMMs are typically used in laptops, notebooks, or other compact devices, not on servers3.

According to the Official CompTIA A+ Core 1 Study Guide (220-1101) 1, the correct answer is A. Document the findings, actions, and solution in the company knowledge base.
The explanation is that after resolving an issue, a technician should always document what was done and how it was fixed. This helps to create a record of the problem and its solution for future reference and also to share knowledge with other technicians.

By documenting the findings, actions, and solution in the company knowledge base, it will help to ensure that if the Issue happens again, the technician or a different technician will be able to quickly and easily find the solution and resolve the Issue. Additionally, it is important to document the solution so that the same Issue does not need to be troubleshot multiple times in the future.

A patient record portal is a web-based application that allows patients to access their health information, such as medical history, test results, prescriptions, and appointments. A patient record portal needs to be secure, reliable, and compliant with the health data regulations of the country or region where it operates1.
The type of cloud that best describes the type of cloud a healthcare company should use for a patient record portal is D. Private. A private cloud is a cloud computing model that is dedicated to a single organization and provides exclusive access and control over its resources and data2. A private cloud can offer the following benefits for a patient record portal:
Enhanced security and privacy: A private cloud can protect the sensitive health data from unauthorized access or breaches by using encryption, firewalls, authentication, and other security measures. A private cloud can also comply with the health data regulations, such as HIPAA in the US or GDPR in the EU, by ensuring that the data is stored and processed within the jurisdiction of the organization3.
Improved performance and reliability: A private cloud can optimize the speed and availability of the patient record portal by using dedicated servers, network bandwidth, and storage capacity. A private cloud can also ensure that the patient record portal can handle high demand and traffic without compromising its quality or functionality3.
Greater customization and flexibility: A private cloud can tailor the patient record portal to the specific needs and preferences of the organization and its patients by using customized applications, interfaces, and features. A private cloud can also scale up or down the resources and services of the patient record portal as needed without affecting its performance or cost3.

The correct answer is B. Duplex.
Duplex printing is the process of printing on both sides of a sheet of paper automatically or manually. Duplex printing can save paper, reduce clutter, and create professional-looking documents. To print on both sides of the paper, the printer must support duplex printing or the user must manually reinsert the pages to print the second side.
Orientation is the direction in which the paper is printed, either portrait (vertical) or landscape (horizontal).
Orientation does not affect the ability to print on both sides of the paper.
Quality is the resolution or sharpness of the printed image, measured in dots per inch (dpi). Quality does not affect the ability to print on both sides of the paper.
Print tray is the part of the printer that holds and feeds the paper into the printer. Print tray does not affect the ability to print on both sides of the paper.
To enable duplex printing on a Windows PC, follow these steps1:
* Open the document for printing, then select File > Print.
* In Settings, select Manually Print on Both Sides, then Print.
* Follow the instructions on the screen to flip and reinsert the pages.
To enable duplex printing on a Mac, follow these steps2:
* Open the document for printing, then select File > Print.
* In Layout, select Two-Sided, then Long-Edge binding or Short-Edge binding.
* Click Print.

Explanation:
Primary Array:
* Drag and drop two 120 GB SSD hard drives to the primary array bay.
* Open the primary array and select RAID 1 as the RAID level. RAID 1 provides fault tolerance of one drive, ability to function with only one drive, easily recoverable data, high redundancy, and very fast on reads. It also does not need to be scalable and uses the minimum number of drives (two) for RAID 1.
* Confirm the configuration and close the primary array.
Secondary Array:
* Drag and drop two 300 GB SSD hard drives to the secondary array bay.
* Open the secondary array and select RAID 0 as the RAID level. RAID 0 provides the best write performance and uses the minimum number of drives (two) for RAID 0. It also provides a total space of
600 GB (300 GB x 2), which meets the requirement.
* Confirm the configuration and close the secondary array.
You have completed the configuration of the storage arrays.
