20+ practice questions focused on Data Governance And Security — one of the most tested topics on the CompTIA DataSys+ (DS0-001) (DS0-001) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Data Governance And Security PracticeA data analyst discovers that raw log files contain unmasked social security numbers. Which data governance practice should be implemented immediately to remediate the risk?
Explanation: Dynamic Data Masking (DDM) masks sensitive data such as SSNs in query results in real time, without altering the stored data, so unauthorized users see masked values while privileged users see the real ones. It is the fastest remediation because it can be applied via policy or ALTER TABLE ... ADD MASKED WITH without a data migration. This directly addresses the risk of unmasked SSNs being exposed to analysts.
Your organization uses Azure Active Directory for access management. You need to ensure that database administrators can only access a specific production Azure SQL instance during a scheduled 4-hour maintenance window. Which control is most appropriate?
Explanation: Microsoft Entra Privileged Identity Management (PIM) is designed specifically for just-in-time privileged access with time-bound activation. It allows DBAs to be eligible for a role but requires them to activate it for a defined window (e.g., 4 hours), after which access is automatically revoked. This directly satisfies the requirement of limiting access to a scheduled maintenance window without permanent standing privileges.
A healthcare analytics team stores patient records in a relational database. A compliance officer requires that any user who queries the 'PatientRecords' table must not be able to view the 'Diagnosis' column unless they belong to the 'ClinicalStaff' role. The database supports column-level permissions. Which action should the data administrator take to meet this requirement?
Explanation: The correct approach is to use a view that excludes the sensitive column and revoke direct table access for non-clinical users. This enforces column-level security by ensuring that users without the 'ClinicalStaff' role cannot access the 'Diagnosis' column through any path. It follows the principle of least privilege and is a common technique in relational databases when native column-level permissions are not granular enough or when additional row filtering is needed.
A data steward at a healthcare analytics firm must ensure that analysts querying the patient encounters table cannot view the Social Security Number column, even though the column must remain intact for downstream billing ETL jobs. Which mechanism should the steward implement to satisfy both requirements?
Explanation: Restricting access by object removes the sensitive column from the analysts' reachable schema while leaving the base table unchanged for billing ETL. A view that omits the Social Security Number column, combined with SELECT granted only on that view, enforces least privilege at the query layer and keeps the data available where it is legitimately needed.
A multinational corporation must comply with GDPR's data transfer restrictions. The company wants to transfer employee payroll data from its EU subsidiary to its US parent. Which mechanism is specifically designed to allow this transfer while providing appropriate safeguards?
Explanation: Standard Contractual Clauses are European Commission-approved contract terms that bind the data importer to GDPR-level protections, making them a purpose-built transfer mechanism for EU-to-US data flows. Consent and adequacy decisions are either impractical or outside the company's control for routine payroll transfers.
