DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
You are designing a data ingestion pipeline for Azure Synapse Analytics. The pipeline will load sensitive financial data from an on-premises SQL Server to a dedicated SQL pool. The data must be encrypted at rest and in transit. Which combination of features should you use?
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 Azure Synapse Transparent Data Encryption (TDE) and enforce TLS 1.2 for connections.
Transparent Data Encryption (TDE) encrypts data at rest in the dedicated SQL pool, and enforcing TLS 1.2 ensures encryption in transit. Option A is wrong because Always Encrypted is for column-level encryption, not for the entire pipeline. Option B is wrong because Azure Disk Encryption is for IaaS VMs, not for Azure Synapse. Option C is wrong because client-side encryption is not built-in for Synapse ingestion.
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 in SQL Server and Azure Key Vault for column encryption.
Why it's wrong here
Always Encrypted is column-level and not designed for bulk ingestion into Synapse.
- ✗
Enable Azure Disk Encryption on the source server and use a VPN gateway.
Why it's wrong here
Azure Disk Encryption is for IaaS VMs, not on-premises or Synapse.
- ✗
Implement client-side encryption using Azure Storage client library and store keys in Microsoft Purview.
Why it's wrong here
Client-side encryption is not natively supported for Synapse ingestion pipelines.
- ✓
Use Azure Synapse Transparent Data Encryption (TDE) and enforce TLS 1.2 for connections.
Why this is correct
TDE encrypts data at rest in Synapse, and TLS secures data in transit.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are designing a data processing solution in Azure Synapse Analytics. The solution must prevent unauthorized access to data at rest and in transit. Which combination of features should you implement?
medium- ✓ A.Enable Transparent Data Encryption (TDE) and enforce TLS 1.2.
- B.Use Azure RBAC and firewall rules.
- C.Use Always Encrypted and column-level security.
- D.Store encryption keys in Azure Key Vault and enable double encryption.
Why A: Transparent Data Encryption (TDE) encrypts data at rest in Azure Synapse Analytics, and enforcing TLS 1.2 ensures encryption of data in transit. Option B (Azure RBAC and firewall rules) controls access but does not provide encryption. Option C (Always Encrypted and column-level security) is primarily for client-side encryption and access control, not comprehensive at-rest encryption. Option D (storing keys in Key Vault and enabling double encryption) relates to key management and infrastructure encryption, but the direct combination of TDE and TLS 1.2 is the required solution.
