Azure SQL Database is the correct choice because it natively supports HIPAA-compliant storage with point-in-time restore for up to 35 days, meeting both the regulatory and recovery requirements for patient records. The service achieves this through automated backups and a configurable retention window from 7 to 35 days, allowing you to restore a database to any point within that period while maintaining transactional consistency—critical for healthcare data. On the Microsoft Azure Data Engineer Associate DP-203 exam, this scenario tests your understanding of how Azure SQL Database combines HIPAA eligibility (when configured with encryption, auditing, and network security) with built-in PITR capabilities, often contrasting it against Azure Cosmos DB or Azure SQL Managed Instance, which have different restore limits or compliance scopes. A common trap is assuming any SQL-based service works, but only Azure SQL Database offers the exact 35-day PITR window out of the box for frequently accessed reporting workloads. Memory tip: think “35 days, one database”—Azure SQL Database’s native PITR is the single, straightforward answer for HIPAA-compliant transactional storage with point-in-time restore.
DP-203 Design and implement data storage Practice Question
This DP-203 practice question tests your understanding of design and implement data storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are designing a data storage solution for a healthcare organization that stores patient records. The solution must comply with HIPAA and support point-in-time restore (PITR) for the last 35 days. The data is frequently accessed for reporting. Which Azure data service should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure SQL Database
Azure SQL Database is the correct choice because it natively supports point-in-time restore (PITR) for up to 35 days (configurable from 7 to 35 days) and is a HIPAA-eligible service when configured with encryption, auditing, and network security. It provides transactional consistency required for patient records and supports frequent reporting workloads with features like columnstore indexes and read replicas.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Cosmos DB
Why it's wrong here
Cosmos DB has PITR but the default retention is up to 30 days, not 35.
✗
Azure Blob Storage with point-in-time restore
Why it's wrong here
Blob Storage has PITR but it is for storage accounts, not optimized for relational reporting.
✓
Azure SQL Database
Why this is correct
Azure SQL Database supports PITR up to 35 days and is HIPAA-eligible when configured properly.

✗
Azure Data Lake Storage Gen2
Why it's wrong here
Data Lake Storage supports soft delete but not point-in-time restore for individual records.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Blob Storage's point-in-time restore (which only applies to container-level recovery of blobs) with the transactional point-in-time restore needed for relational patient records, or they assume Cosmos DB's multi-model capabilities make it suitable for structured healthcare data despite its lack of ACID compliance and limited backup retention.
Detailed technical explanation
How to think about this question
Azure SQL Database's PITR leverages automated backups (full, differential, and transaction log) to restore a database to any point within the retention window, with a granularity of up to one minute. Under the hood, the service uses geo-redundant storage (RA-GRS) for backups by default, and the retention period is set at the server or database level via the `backupRetentionDays` property. For HIPAA compliance, Azure SQL Database supports Transparent Data Encryption (TDE), Always Encrypted, and audit logging via Azure SQL Auditing, which are critical for protecting protected health information (PHI).

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
