The scenario described is characteristic of a malware tactic known as scareware, where users are tricked into installing malware through false alerts claiming that their system is infected. The anti-malware software installed in response to a pop-up is likely malicious, causing the system to run slowly and display frequent pop-ups.

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

To prevent security issues related to an employee using the same password for multiple applications and websites, implementing expiration policies (B) is best. Password expiration policies require users to change their passwords at regular intervals, which helps to mitigate the risks associated with password reuse. Regularly changing passwords reduces the chances of unauthorized access from compromised credentials​​.

The most important environmental control to maintain the safety of a data center is Temperature control (A). Proper temperature control is crucial to prevent overheating, which can lead to hardware failure, reduced performance, and shortened equipment lifespan. Data centers house high-density computing equipment that generates significant amounts of heat, making effective temperature management essential for maintaining operational stability and reliability​​.

In a Small Office/Home Office (SOHO) setup, the technician is most likely to configure mapped drives on a new PC. Mapped drives allow for easy access to shared resources such as files and printers on the network. This setup facilitates file sharing and collaboration within a small network, making it an essential configuration for SOHO environments.

An image backup captures a complete snapshot of the entire system at a specific point in time, including the operating system, installed applications, user profiles, and system settings. This method is most suitable for backing up the components listed in the question because it ensures that every aspect of the workstation, from the core OS to individual user settings, is preserved and can be restored in its entirety. This is crucial for quickly recovering a system to a fully operational state after a failure or when migrating to new hardware. Other methods like differential, synthetic, and archive backups do not provide the comprehensive one-step restoration capability that an image backup offers for the complete system recovery.

When an email is encrypted and the recipient cannot open it, the issue typically revolves around the need for encryption keys. Encryption keys are used to encode and decode the email content, ensuring that only authorized recipients with the correct key can access the information. In this scenario, the user would need to receive the appropriate decryption key from the sender to unlock and read the encrypted email. This exchange ensures that sensitive information remains secure during transmission and is only accessible to intended recipients.

The app file type is designed to run under macOS as an application file bundle. macOS uses application bundles to store executable files and related resources, such as libraries, image files, and localized content, in a single directory hierarchy. This approach simplifies application management and execution within the macOS environment​​.
