• B. Share data publicly without restrictions.
• C. Audit access; consider guest accounts and data separation.
• D. Use email attachments for all sharing.

Answer: (A)

External data sharing should be secure, governed, and auditable, using a centralized sharing mechanism rather than ad hoc methods. Sharing data through OneLake with proper ACLs ensures you grant access only to the right external partners and only to the exact data surfaces intended. Applying data masking protects sensitive fields so partners can work with the necessary information without exposing private or regulated data. Enforcing RBAC means permissions are tied to roles, so users and partner accounts receive the least privilege needed for their tasks. Auditing access creates a clear trail for compliance and security investigations, helping you detect unusual activity and prove who did what. Using guest accounts to onboard external collaborators, along with data separation to keep partner data isolated from internal datasets, makes revocation and monitoring straightforward when a partnership ends. Public sharing or sending data without controls lacks governance and visibility, while relying on only auditing or only partial controls leaves gaps in security and compliance.
