A+ 220-1102 Syllabus Exam Questions Answers

Device data encryption (Option D) ensures that even if the device is lost or stolen, its data cannot be accessed without proper credentials, even while offline. Encryption protects the data at rest, making it unreadable without the decryption key.

Remote wipe (Option A) requires the device to be online to receive the wipe command.

Mandatory screen locks (Option B) provide a layer of security but can be bypassed with physical access in some cases.

Location applications (Option C) help track the device but don't protect data.

Comprehensive and Detailed In-Depth Explanation:

Biometrics (such as fingerprint scanning, retinal scanning, or facial recognition) is the most secure method because it authenticates individuals based on unique physical characteristics that cannot be easily duplicated or shared.

A. Smart cards – More secure than passwords but can be lost or stolen.

B. Key fobs – Provide access control but can be stolen or cloned.

D. Security guard – Can enhance security but is prone to human error and does not offer automated access control.

The next step after isolating the system is to perform a system scan to remove the malware (Option C). Since ransomware is suspected, running a comprehensive malware scan can help identify and remove the malicious software. It is crucial to deal with the active threat before taking further actions.

Scheduling an antivirus scan and system update (Option A) may help, but the immediate concern is identifying and removing the ransomware.

Educating the end user (Option B) is important but should happen after the immediate threat is resolved.

Creating a system restore point (Option D) would not be useful at this point since the system is infected.
