DS0-002 practice examsFinished
CompTIA DataSys+ V2
The vendor-neutral database administration exam, for people who will meet more than one engine: the relational and non-relational models with normalisation and its deliberate reversal, the SQL families and the objects and constraints that keep data correct, deployment choices and what a managed service costs in control, then security and governance vocabulary, the backup shapes and what actually enables point-in-time recovery, availability distinguished from recoverability, and troubleshooting by constraint.
What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
What the exam covers
| Database Fundamentals | 19% |
| Database Deployment | 17% |
| Database Management and Maintenance | 18% |
| Data and Database Security | 19% |
| Business Continuity | 14% |
| Data Integration | 13% |
Two sample questions
1. Log events arrive as JSON with keys that vary slightly between versions. How is this data classified?
- Structured
- Unstructured
- Relational tabular
- Semistructured — correct
Why: Semistructured data carries its own tags or keys without a fixed schema.
2. A team must enforce that every order has a valid status from a list. What should you use?
- A lookup table with a foreign key — correct
- A free-text status column with guidance notes
- A trigger that sends email
- A view without constraints
Why: Reference tables with foreign keys restrict values to a defined list.
