Which of the following is the GREATEST concern for an organization subject to cross-border data transfer regulations when using a cloud service provider to store and process data?

The term "cross-border data transfer" directly points to the geographical location of data processing and storage. The greatest regulatory concern, under frameworks like the GDPR, is whether the data is transferred to a jurisdiction with an "adequate" level of data protection. Storing data in a region with different and potentially weaker requirements can result in non-compliance, leading to severe legal and financial penalties. This jurisdictional issue is the most fundamental concern specific to cross-border scenarios.

A. The right to audit is a crucial contractual control for vendor oversight but is a general due diligence concern, not one specific to cross-border regulations.
B. Not anonymizing personal data is a general data protection failure, relevant regardless of whether the data transfer is cross-border or domestic.
C. The extent of provider access is a critical access control issue but does not directly address the specific legal requirements governing data movement between countries.
