A multinational company is transferring data between its US and EU subsidiaries. Which mechanism is most effective for ensuring cross-border data transfer compliance after the invalidation of previous frameworks?
SCCs provide enforceable contractual safeguards between exporter and importer, while a TIA assesses whether local surveillance laws undermine those protections. Together they satisfy the post-Schrems II requirement that transfers be governed by supplementary measures, not mere contractual clauses alone.
Why this answer
Standard Contractual Clauses (SCCs) are the European Commission-approved contractual safeguards for transferring personal data to third countries, and pairing them with a Transfer Impact Assessment (TIA) addresses the post-Schrems II requirement to evaluate the destination country's laws and supplement protections where needed. Together they form the most defensible mechanism for lawful EU-US transfers after prior frameworks were invalidated. This combination is explicitly endorsed by the EDPB.
Exam trap
CDPSE often tests outdated frameworks (Privacy Shield) as if still valid, and confuses supplementary safeguards like encryption with actual lawful transfer mechanisms, luring candidates toward technical controls over legal instruments.
How to eliminate wrong answers
Option A is wrong because encryption in transit does not by itself provide a lawful transfer mechanism under GDPR Chapter V; it is a supplementary safeguard, not a transfer tool. Option B is wrong because an internal group privacy policy is a Binding Corporate Rules-like instrument only if formally approved by supervisory authorities; an unapproved internal policy is not an adequacy decision. Option D is wrong because the US Commerce Department privacy program (Privacy Shield) was invalidated by Schrems II in July 2020, so self-certification under it no longer provides a valid transfer basis.
