Important DS0-001 Exam-Code Notice

CompTIA launched DS0-001 on July 18, 2023. Its published certification information estimates retirement during 2026, but a specific retirement date has not been confirmed.

Candidates should verify that DS0-001 remains available before purchasing this course or an examination voucher. Check the official CompTIA DataSys+ certification page and confirm that DS0-001 is available in the Pearson VUE scheduling system.

If CompTIA announces a replacement exam, learners should compare the new objectives with this DS0-001 course before continuing their preparation.

About the DS0-001 Exam

The CompTIA DataSys+ DS0-001 exam contains a maximum of 90 questions and allows 90 minutes for completion. Candidates may encounter single-response questions, multiple-response questions and performance-based questions.

CompTIA recommends two to three years of experience in a database administrator role. There are no formal certification prerequisites, but practical experience with databases, SQL, operating systems, networking and security is strongly beneficial.

The examination validates your ability to:

• Understand database structures and architecture

• Develop and modify SQL code

• Deploy database systems

• Monitor database health and performance

• Conduct routine database maintenance

• Troubleshoot database problems

• Protect data and database infrastructure

• Implement backup and recovery processes

• Support high availability and business continuity

Score and Pass Mark

The required passing score for the CompTIA DataSys+ DS0-001 examination is 700 on a scale of 100–900.

This is a scaled score rather than a direct percentage of correctly answered questions. CompTIA does not disclose the precise number of questions candidates must answer correctly. Questions may also contribute differently to the final score.

Candidates have approximately one minute per question when the maximum number of questions is presented. However, performance-based questions may require additional time.

This course includes timed quizzes, database-administration scenarios, practical exercises and five full-length mock examinations. These materials help learners improve accuracy, problem-solving ability and exam pacing.

The official certification is awarded only after passing the authorized DS0-001 examination. Candidates can confirm availability and schedule through the CompTIA Pearson VUE testing portal.
