220-1102 Question 213
Single answerPrivacyA technician is preparing several Windows laptops for a temporary HR recruiting event. Recruiters will use the laptops to review candidate information, including resumes and interview notes, in a public conference area. The company wants to reduce the risk of people nearby viewing sensitive information on the screens without changing the recruiting software. Which action should the technician take FIRST to best address this privacy concern?
- A
Install privacy screen filters on the laptop displays
- B
Enable full-disk encryption with BitLocker on each laptop
- C
Require complex passwords and shorter account lockout timers
- D
Disable browser cookies and cached files after each session
Show answer and explanation
Correct answer: A
Explanation
The best answer is to install privacy screen filters because the scenario specifically describes a visual privacy risk in a public area. In A+ Core 2 objectives, privacy controls include methods to reduce exposure of sensitive information to unauthorized viewers, such as using privacy screens and being aware of shoulder surfing risks. While encryption, password policies, and browser data controls are all valid security measures, they address different threats: data theft from lost devices, unauthorized account access, and residual browsing data. Best practice is to match the control to the risk. For public-facing or open-office use cases involving sensitive personal data, a privacy filter is a direct and practical mitigation.
- A. Correct.
Correct. Privacy screen filters are designed to limit the viewing angle of a display, helping prevent visual access by nearby people in public or shared spaces. In this scenario, the main risk is shoulder surfing and visual exposure of candidate data, so a privacy filter directly addresses the problem without requiring software changes.
- B. Incorrect.
Incorrect. BitLocker is an important security control that protects data at rest if a device is lost or stolen, but it does not prevent someone standing nearby from reading information displayed on the screen. This option improves security, but it does not best address the immediate privacy issue described.
- C. Incorrect.
Incorrect. Strong passwords and lockout settings help protect account access from unauthorized logins, but they do not stop someone from viewing confidential data while an authorized recruiter is actively using the device. This is a common misconception because authentication controls are important, but they do not solve visual privacy concerns.
- D. Incorrect.
Incorrect. Clearing cookies and cached files can reduce leftover browsing artifacts and protect some private data after use, but it does not prevent on-screen information from being seen by others during active use. This option focuses on residual data privacy rather than live visual privacy.
