Explanation:
Although updating the anti-malware software and running scans are important steps in removing malware, they may not be sufficient to permanently remove the malware if the user keeps engaging in behaviors that leave the system vulnerable, such as downloading unknown files or visiting malicious websites. Therefore, educating the user on safe computing practices is the best way to prevent future infections and permanently remove the malware.
Enabling System Restore, Booting into safe mode, and scheduling a scan are not the most efficient ways to permanently remove the malware. Enabling System Restore and Booting into safe mode may help in some cases, but they may not be sufficient to permanently remove the malware. Scheduling a scan is also important for detecting and removing malware, but it may not be sufficient to prevent future infections.

Explanation:
When disposing of non-compliant Ethernet cards, the most environmentally friendly option is to use a dumpster for recycling plastics. This method is the most effective way to reduce the amount of waste that is sent to landfills, and it also helps to reduce the amount of energy used in the production of new materials. Additionally, recycling plastics helps to reduce the amount of toxic chemicals that can be released into the environment. According to CompTIA A+ Core 2 documents, "The most environmentally friendly disposal method for non-compliant Ethernet cards is to use a dumpster for recycling plastics. This method is the most effective way to reduce the amount of waste that is sent to landfills, and it also helps to reduce the amount of energy used in the production of new materials."

Explanation:
change management process can help ensure that owners are notified of changes being made and can monitor them for performance impact (A). This can help prevent unexpected issues from arising.

Explanation: Before starting a bare-metal installation of Windows 10, ensuring that there is sufficient storage space on the system's hard drive or SSD is crucial. This is because the installation files need enough room to be copied and for the operating system to be installed and function properly. Without adequate storage, the installation process can fail or the operating system might not perform optimally. Other prerequisites like internet connection, product key, and specific firmware types might be necessary at different stages of installation or activation, but the fundamental requirement is enough storage space to accommodate the new OS.

Explanation:
The technician should run the System File Checker (SFC) first to correct file corruption errors on computers after a power outage. SFC is a command-line utility that scans for and repairs corrupted system files. It can be run from the command prompt or from the Windows Recovery Environment. Rebuilding the Windows profiles, restoring the computers from backup, and reimaging the computers are more drastic measures that should be taken only if SFC fails to correct the issue1.

Explanation: A rollback plan describes the process of reverting a system to its previous state after a failed upgrade or change. This ensures system stability and functionality by restoring known good configurations and is a crucial part of change management to minimize disruptions in case of unsuccessful updates.

Explanation: For a company with geographically dispersed staff and the need to keep devices updated, using cloud-based endpoint management software is the most efficient method. This type of software allows IT administrators to remotely manage and push updates to company devices, regardless of their location. It ensures that all devices remain up to date with the latest security patches and software updates without requiring physical access or user intervention. This approach is scalable, reduces the risk of unpatched vulnerabilities, and is convenient for both the IT department and the end-users.

Explanation:
According to CompTIA A+ Core 2 objectives, a full backup stored off-site provides the greatest protection against data loss in the event of a ransomware attack or other data disaster. By storing the backup in a separate physical location, it is less likely to be affected by the same event that could cause data loss on the original system. Cold storage is a term used for data archiving, which typically refers to a long-term storage solution that is used for retaining data that is infrequently accessed, but still needs to be kept for regulatory or compliance reasons.

Explanation: To resolve an issue of low storage space on a Windows computer, the best approach is to Run Disk Cleanup (B). Disk Cleanup is a built-in utility that helps users free up space on their hard drives by deleting temporary files, system files, and other unnecessary files that are no longer needed, thereby resolving low storage space issues

Explanation:
BitLocker is a disk encryption tool that can be used to encrypt the hard drive of a Windows laptop. This will protect the data stored on the drive in the event that the laptop is lost or stolen, and will help to reduce the risk of data loss. Additionally, BitLocker can be configured to require a PIN or other authentication in order to unlock the drive, providing an additional layer of security.

Explanation: Turning off inheritance on the specific folder requested by the manager and setting the requested permissions, followed by turning on inheritance under the child folders, ensures that only the immediate team has access to the confidential material while maintaining the broader permissions structure for other folders and files. This action isolates the folder's permissions from the top-level inheritance, providing a focused security measure for sensitive content.
