20+ practice questions focused on Data Systems Management — 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 Systems Management PracticeYou are auditing database logins to ensure compliance. You need to identify users who have not logged in for over 90 days. Which system view or dynamic management function is most appropriate?
Explanation: sys.dm_server_principals (or sys.syslogins in older versions) combined with session monitoring is typical, but in SQL Server, there is no direct 'last login' property; however, auditing tools are the standard way to track this.
A DBA is configuring an Always On Availability Group in SQL Server. To ensure that the secondary node can be used for read-only reporting tasks, which setting must be correctly configured in the Availability Group replica settings?
Explanation: The 'Readable Secondary' property must be set to 'Read-intent only' or 'Yes' to allow the secondary node to accept connections for reporting tasks.
A database administrator wants to move a heavily accessed table to a different physical storage tier to improve performance. In SQL Server, what is the best way to move the table data while retaining the clustered index?
Explanation: Moving the clustered index to a new filegroup moves the data pages of the table to that filegroup, effectively changing the physical storage location.
A database administrator needs to ensure that a SQL Server transaction log does not grow uncontrollably during a high-volume ETL process. Which recovery model should be configured to allow for periodic log truncation while maintaining a balance between performance and recovery needs?
Explanation: The Full recovery model requires log backups to truncate the transaction log. The Simple recovery model automatically truncates the log, but the Bulk-Logged recovery model is specifically designed to minimize log space usage during large-scale bulk-load operations.
In PostgreSQL, you need to monitor the performance of your long-running queries. Which view is the most appropriate to inspect the query execution statistics for all active sessions?
Explanation: pg_stat_activity provides information about the current state of each backend process, including the query being executed.

Start with 10 questions to gauge your current understanding of Data Systems Management. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Data Systems Management questions on the DS0-001 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Data Systems Management is tested as part of the CompTIA DataSys+ (DS0-001) (DS0-001) blueprint. Practicing with targeted Data Systems Management questions ensures you can handle any format or difficulty that appears.
