Question 9
Domain 1 — Privacy Governance and Program ManagementWhich of the following is the MOST important consideration to ensure privacy when using big data analytics?
Correct answer: C
Explanation
Privacy depends on people knowing what data is gathered and how it will be used. Transparency about the data being collected supports informed consent and limits hidden collection, which is a core privacy safeguard in big data analytics.
Why each option is right or wrong
A. Maintenance of archived data
Archived data maintenance is a retention and operations issue, not the primary privacy safeguard.
B. Disclosure of how the data is analyzed
Analysis disclosure helps governance, but privacy begins with knowing what data is collected.
C. Transparency about the data being collected
Under GDPR Article 5(1)(a) and Article 12–14, personal data processing must be fair and transparent, and the controller must provide clear notice of what data is collected, the purposes, recipients, and retention period. In big data analytics, the privacy risk is not just volume but opaque secondary use; without disclosure, individuals cannot exercise rights under Articles 15–22 or give informed consent under Article 7 where consent is relied on.
D. Continuity with business requirements
Business continuity concerns operational alignment, not individual privacy protection.
