AnNDA (Non-Disclosure Agreement)is used to ensure confidentiality of sensitive company information, especially when interacting with external parties.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“An NDA ensures that confidential information is not disclosed to unauthorized individuals, especially important in external communications.”

Multi-Factor Authentication (MFA) requires at least two different types of authentication factors:

Something you know (e.g., password or PIN)

Something you have (e.g., smartphone or hardware token)

Something you are (e.g., fingerprint or facial recognition)

Option A, sending a code to the user’s phone, is an example of " something you have " — a physical device that receives a one-time passcode. Combined with a password, this forms a proper MFA implementation.

B. Date of birth is another knowledge-based factor (like a password), not a second factor type.

C. Solving a math problem is not a recognized authentication factor.

D. A PIN is also " something you know " and does not count as a distinct MFA factor when paired with a password.

These symptoms strongly suggest malware activity—likely from the newly installed app. The first action should be torun a malware scanto detect and isolate malicious software.

FromQuentin Docter – CompTIA A+ Study Guide:

“Signs of malware infection include rapid battery drain and overheating. The first step should be a malware scan using trusted mobile antivirus apps.”
