- A
Use Always Encrypted with secure enclaves for specific columns.
Always Encrypts protects data at rest and in use.
- B
Implement column-level security to filter sensitive columns.
Why wrong: Column-level security restricts access, not encryption.
- C
Enable Transparent Data Encryption (TDE) on the SQL pool.
TDE encrypts data files at rest.
- D
Configure Dynamic Data Masking on tables containing sensitive data.
Why wrong: Dynamic Data Masking hides data in query results, not at rest.
- E
Assign Azure RBAC roles to restrict access to the storage account.
Why wrong: RBAC controls access, not encryption at rest.

DP-203 Always Encrypted Practice Question
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: always Encrypted. 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.
Which TWO actions should you take to secure data at rest in Azure Synapse Analytics dedicated SQL pools?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Always Encrypted with secure enclaves for specific columns.
Option A is correct: Always Encrypted with secure enclaves encrypts sensitive columns at rest and during query processing. Option C is correct: Transparent Data Encryption (TDE) encrypts the entire database at rest. Options B, D, and E are incorrect: column-level security and Dynamic Data Masking control access or mask output but do not encrypt at rest; Azure RBAC manages permissions, not encryption.
Key principle: Always Encrypted

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Always Encrypted
- Transparent Data Encryption (TDE)
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
Always Encrypted
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.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
