Cryptominersexploit system resources to mine cryptocurrency, often without user consent, leading to high CPU and GPU usage.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Cryptomining malware can cause significant performance degradation by monopolizing system resources like CPU and GPU to mine digital currency."

Remote wipeis a mobile device management (MDM) feature that allows administrators to erase data remotely if a device is lost or stolen, preventing unauthorized access to corporate or personal information.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Remote wipe features enable a device to be cleared of all sensitive data if it is lost or stolen. This is one of the most effective ways to prevent unauthorized access to corporate resources."

Comprehensive and Detailed Explanation From Exact Extract:
Operating systems periodically reach a status known as "end of life" (EOL), at which point the developer (e.
g., Microsoft, Apple) ceases to provide security updates, patches, or technical support. When this happens, the OS becomes vulnerable and non-compliant with security best practices, which is why organizations typically receive advance notifications from vendors or support teams.
A: Manufacturer support expiration only applies to hardware, not OS patching.
C: Security software may be upgraded or removed, but that does not affect patching the OS itself.
D: The release of a new version doesn't automatically stop updates for the current version.

Videoconferencingplatforms allow real-time face-to-face communication and are ideal for collaborative training sessions involving remote employees.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Videoconferencing tools such as Zoom or Microsoft Teams are specifically designed for real-time communication and training, making them ideal for executive or large-group meetings."

Comprehensive and Detailed Explanation From Exact Extract:
In enterprise environments, network-based deployment solutions (such as Windows Deployment Services or SCCM) allow administrators to push images across the network to hundreds of devices efficiently. These tools support hardware-specific drivers (for different vendor classes) and can accommodate user-group configurations using task sequences or answer files.
A: and B (xcopy and robocopy) are file-level tools and not designed for full OS image deployment.
C: Using local tools per device is inefficient for large-scale rollouts (800 devices).
D: Network-based deployment is the industry standard for this scale.
