CompTIA 220-1202 Exam Dumps

Older tablets may not support newer app versions due toincompatible or unsupported operating systems. App developers often drop support for outdated OS versions.

FromTravis Everett -- CompTIA A+ All-in-One Exam Guide:

''When an app won't install on an older device, check the OS version. Most apps require a minimum OS level for compatibility and security.''

The correct answer is to run a full malware scan using updated antimalware definitions. While svchost.exe is a legitimate Windows system process, malware can masquerade as or inject code into this process. Given the recent installation of untrusted software and the suspicious memory consumption, malware is a likely cause. Running a full scan with updated definitions is the appropriate diagnostic step before taking destructive actions.

Terminating svchost.exe is incorrect and dangerous—it can crash the system or make it unstable since svchost.exe hosts critical Windows services. Reinstalling Windows or replacing the hard drive are premature and unnecessary before diagnosis. Disabling startup programs does not address the immediate problem and would not resolve a malware issue.

To ensure the authenticity of a downloaded application, the most reliable method is to verify the file's hash (e.g., SHA256, MD5) against the value provided by the legitimate vendor. If the hash values match, the file has not been altered or tampered with. This verification confirms the integrity and authenticity of the executable.

B . Process IDs are dynamic and not unique to specific software.

C . Running in safe mode doesn't validate legitimacy---it only runs the app in a minimal environment.

D . File names can be spoofed; matching the name does not prove authenticity.

CompTIA A+ 220-1102 Objective 2.2: Compare and contrast authentication and software integrity verification methods.

Study Guide Section: Hash verification for software authenticity and digital integrity

When a Windows system cannot boot even into Safe Mode, the appropriate diagnostic and recovery approach is to boot from installation media and access the Advanced Startup Options (also called Windows Recovery Environment). From there, you can run Startup Repair, check system files, view system logs, and attempt recovery without immediately reinstalling. This is less destructive than a clean install and often resolves the underlying issue.

Immediately reinstalling is excessive before attempting built-in recovery tools. Simply reseating hardware may help in some cases, but does not address software-level boot issues. Forcing multiple power cycles can corrupt the file system further and is not a systematic approach. Replacing the drive and transferring the license is unnecessary without first confirming a hardware failure. The Recovery Environment and Startup Repair are designed for this exact scenario and should be attempted first.

The correct answers are D. Use PIN authentication and F. Enable screen timeout, because both controls directly protect a mobile device from unauthorized physical access. Physical access controls are designed to prevent someone from using a device if it is lost, stolen, or left unattended.

According to the Quentin Docter -- CompTIA A+ Complete Study Guide, mobile device security begins with lock-screen controls, such as PINs, passwords, biometrics, and automatic locking mechanisms. A PIN authentication requirement ensures that even if an attacker physically possesses the device, they cannot access its contents without the correct credentials.

The guide further explains that screen timeout (automatic locking after inactivity) is a critical security feature. Without it, a device left unattended---even briefly---could be accessed by unauthorized individuals. Enabling a short timeout greatly reduces this risk.

The Travis Everett & Andrew Hutz -- All-in-One Exam Guide reinforces that VPNs and antivirus software protect data in transit and against malware, not physical access. Likewise, disabling hotspots and enabling location services are management or tracking features, not access prevention mechanisms.

The Mike Meyers / Mark Soper Lab Manual emphasizes that physical security controls focus on preventing interaction with the device itself, making PIN authentication and automatic screen locking the most effective measures.

Therefore, D and F are the correct answers.
