Question 19
Domain 5: Privacy by DesignA smart TV lets users turn off ad personalization, but cross-device measurement continues unless they find a second, hidden menu. What is the biggest privacy problem?
Correct answer: B
Explanation
The biggest privacy problem is that the interface gives users an apparent opt-out while keeping cross-device measurement active in a hidden menu, so the choice is not meaningful. This undermines user autonomy because “turn off ad personalization” suggests broad privacy control, but the real tracking continues unless users discover the second setting.
Why each option is right or wrong
A. The TV uses software rather than hardware controls.
B. The preference design undermines meaningful user choice and creates misleading control.
Under GDPR Article 7(2), consent and preference mechanisms must be presented in a way that is clear and distinguishable, and Article 12 requires transparent, intelligible information so users can exercise real control. A setting that appears to disable ad personalization while leaving cross-device measurement active behind a second hidden menu is misleading by design, because the user is not given a single, effective choice over the processing at issue. That makes the privacy control illusory rather than meaningful, which is the core defect here.
C. The TV probably uses too much bandwidth.
D. The hidden menu is acceptable because it still technically exists.
