Question 28
Domain 4 — Privacy Risk Assessment and Compliance ValidationWhich of the following tracking technologies associated with unsolicited targeted advertisements presents the GREATEST privacy risk?
Correct answer: A
Explanation
Online behavioral tracking presents the greatest privacy risk because it follows a user’s activity across websites and apps to build a detailed profile of interests, habits, and identity. That broad collection and aggregation of personal data makes unsolicited targeted advertising far more invasive than single-site or limited tracking methods.
Why each option is right or wrong
A. Online behavioral tracking
Online behavioral tracking is the most privacy-invasive form because it uses third-party cookies, pixels, device identifiers, or similar mechanisms to monitor a person’s activity across multiple websites and apps, then aggregates that data into a persistent profile for ad targeting. By contrast, limited or first-party tracking is confined to a single service and does not create the same cross-context dossier of browsing habits, interests, and identity-linked inferences.
B. Radio frequency identification (RFID)
RFID mainly identifies tagged physical objects nearby, not broad cross-site ad profiling behavior.
C. Website cookies
Cookies often store session or site preferences; alone they are narrower than behavioral tracking.
D. Beacon-based tracking
Beacon tracking is usually proximity-based and location-limited, not comprehensive long-term behavior aggregation.
