When a system drive is nearly full, the most appropriate tool to free up space is Disk Cleanup. This built-in Windows utility scans the drive and allows users to safely remove temporary files, system cache, recycle bin contents, and other unnecessary files that consume disk space. Resource Monitor provides detailed real-time system resource usage but does not free space. Disk Defragment reorganizes fragmented files to improve performance but does not delete data. Disk Management is used to partition and format drives but does not clean files. Disk Cleanup is a primary maintenance tool covered in the Core 2 operating system domain to manage storage and optimize system performance.

When a smartphone is lost, especially one that might contain sensitive or private data, the primary concern is to ensure that any data on the device cannot be accessed by unauthorized persons. Among the options provided:

Remote lock: This option will lock the device remotely, preventing access. However, it does not remove the data and might not be effective if the device is powered off or reset.

Remote wipe: This is the best option as it allows the technician to erase all data from the device remotely, ensuring that sensitive information is not accessible to anyone who finds or steals the device.

Remote access: This option would allow a technician to access the device remotely, but it would not directly prevent unauthorized access or data breaches.

Remote encrypt: Encrypting the device remotely might not be possible if the device is not accessible or turned on, and it does not remove existing data which could be at risk.

For ensuring data protection against local natural disasters and hardware failures, the best approach is to use an off-site solution that provides redundancy and is resilient to local disruptions.

Using an agent-based cloud backup solution: This method involves backing up data to a remote cloud server, providing protection against local disasters like floods, fires, or hardware failures since the data is stored off-site and can be accessed from anywhere.

Implementing a grandfather-father-son backup rotation: While effective for managing local backups, this method typically involves physical media which could still be vulnerable to local disasters.

Automating backups to a local network share: This keeps the backups within the same physical location, making them susceptible to local disasters.

Saving files manually to an external drive: This method is prone to human error and doesn't provide automated or off-site protection.

When dealing with a malware-infected system, isolating the system from the network and disabling System Restore are critical initial steps. The next step in the malware removal process should be:

Perform an antivirus scan: This helps to identify and remove the malware from the system. Running a thorough scan using updated antivirus software is essential to detect and clean any malicious files.

Run Windows updates: This is important for system security but should be done after the malware is removed to avoid further issues.

Reimage the system: This is a more drastic measure and should be considered if the antivirus scan cannot fully clean the system.

Enable System Restore: This should only be done after the system is confirmed to be clean.

Badge readers are devices that scan employee or visitor credentials, logging entries and exits from restricted areas. Video surveillance (B) provides a visual record but does not directly control access. Bollards (A) and fences (D) provide physical security but cannot detect or record access events.

Time Machine (Option A) is macOS's built-in backup application. It allows users to automatically back up their entire system, including apps, music, photos, emails, and system files. Time Machine provides an easy way to restore files from a previous state or recover from a system failure.

FileVault (Option B) is used for encrypting data, not for backups.

Keychain (Option C) is a password management tool.

Mission Control (Option D) manages open windows and desktops but has no backup functionality.
