DP-203 Always Encrypted Practice Question
Which TWO actions should you take to secure data at rest in Azure Synapse Analytics dedicated SQL pools?
⚠ Common exam trap
Candidates often confuse Always Encrypted with Dynamic Data Masking or mistake TDE for a column-level solution. Remember: TDE encrypts the whole database, Always Encrypted protects specific columns.
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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use Always Encrypted with secure enclaves for specific columns.
Why this is correct
Always Encrypts protects data at rest and in use.
- ✗
Implement column-level security to filter sensitive columns.
Why it's wrong here
Column-level security restricts access, not encryption.
- ✓
Enable Transparent Data Encryption (TDE) on the SQL pool.
Why this is correct
TDE encrypts data files at rest.
- ✗
Configure Dynamic Data Masking on tables containing sensitive data.
Why it's wrong here
Dynamic Data Masking hides data in query results, not at rest.
- ✗
Assign Azure RBAC roles to restrict access to the storage account.
Why it's wrong here
RBAC controls access, not encryption at rest.

| 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 |
