Question 81 - ARA-C01 discussion

A healthcare company that handles PHI data must ensure compliance with relevant privacy standards, such as HIPAA, HITRUST, and GDPR.Snowflake provides several features and best practices to help customers meet their data protection and compliance requirements1.

One best practice recommendation is to use, at minimum, the Business Critical edition of Snowflake.This edition provides the highest level of data protection and security, including end-to-end encryption with customer-managed keys, enhanced object-level security, and HIPAA and HITRUST compliance2. Therefore, option A is correct.

Another best practice recommendation is to create Dynamic Data Masking policies and apply them to columns that contain PHI. Dynamic Data Masking is a feature that allows masking or redacting sensitive data based on the current user's role.This way, only authorized users can view the unmasked data, while others will see masked values, such as NULL, asterisks, or random characters3. Therefore, option B is correct.

A third best practice recommendation is to use the External Tokenization feature to obfuscate sensitive data. External Tokenization is a feature that allows replacing sensitive data with tokens that are generated and stored by an external service, such as Protegrity.This way, the original data is never stored or processed by Snowflake, and only authorized users can access the tokenized data through the external service4. Therefore, option D is correct.

Option C is incorrect, because the Internal Tokenization feature is not available in Snowflake.Snowflake does not provide any native tokenization functionality, but only supports integration with external tokenization services4.

Option E is incorrect, because rewriting SQL queries to eliminate projections of PHI data based on current_role() is not a best practice. This approach is error-prone, inefficient, and hard to maintain.A better alternative is to use Dynamic Data Masking policies, which can automatically mask data based on the user's role without modifying the queries3.

Option F is incorrect, because avoiding sharing data with partner organizations is not a best practice. Snowflake enables secure and governed data sharing with internal and external consumers, such as business units, customers, or partners. Data sharing does not involve copying or moving data, but only granting access privileges to the shared objects.Data sharing can also leverage Dynamic Data Masking and External Tokenization features to protect sensitive data5.
