Comprehensive and Detailed Explanation From Exact Extract:

An "OS Not Found" error typically indicates that the computer is attempting to boot from a drive that doesn't contain a valid operating system or bootable partition. The presence of a USB drive might be confusing the boot order. Therefore, the first step a technician should take is to verify and adjust the boot sequence in the system’s firmware (BIOS or UEFI). It's possible that the USB drive is being prioritized over the internal hard drive, which may cause the system to miss the OS entirely.

A. Running data recovery tools is premature before confirming boot order.

B. Repartitioning the disk would destroy existing data—this should not be done until confirmed the OS is actually missing.

D. Switching between UEFI and BIOS (legacy mode) might help in rare cases, but it is not the first step in standard OS boot issue troubleshooting.

SSH (Secure Shell)allows encrypted console sessions to access and administer remote servers.

FromQuentin Docter – Complete Study Guide:

The su (substitute user) command is used in Linux to switch to another user account, most commonly to escalate privileges by switching to the root (administrator) account. It allows administrative tasks to be performed in a terminal session.

A. runas is a Windows command for executing a program under another user's context.

B. cmcl is not a valid Linux or administrative command.

C. net user is a Windows command for managing local user accounts.

A VPN creates a secure tunnel from the user’s home network into the corporate network, providing the necessary routing and access controls for the laptop to reach internal file servers. Without a VPN, the device remains outside the corporate LAN and cannot directly reach protected resources.

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.

Persistent pop-ups urging antivirus updates are likelyscareware or adware. The correct approach is toverify existing antivirus settings, run a trusted security scan, and avoid interacting with unknown pop-ups.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Users should verify antivirus status using trusted tools before responding to alerts. Fake updates are common vectors for malware.”

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.”

Comprehensive and Detailed Explanation From Exact Extract:

This is likely arogue antivirusor scareware tactic. The user shouldnot click "OK"and instead check Windows Security (or third-party antivirus) status and ensure real-time protection is enabled.

FromMark Soper – Mike Meyers' Lab Manual:

“Users should verify security center settings if receiving suspicious pop-ups. Clicking unknown software updates can install malware. It’s safer to validate protection through legitimate system tools.”

Thepowercfg commandis a built-in utility for controlling power settings including hibernation. It can be used in scripts and does not require domain access.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“The powercfg command provides granular control of power settings, useful for scripting and configuring systems without Group Policy access.”
