- A
Enable Azure Storage Service Encryption (SSE) with platform-managed keys and configure Azure Databricks to use a VNet injection.
Why wrong: SSE with platform-managed keys does not give customer control; VNet injection helps with network isolation but not encryption key management.
- B
Apply an Azure Policy to require encryption and assign a built-in GDPR blueprint.
Why wrong: Policy enforces compliance but does not directly implement encryption; encryption must be configured separately.
- C
Use Azure Security Center to monitor for data exposure and enable Azure Defender for Storage.
Why wrong: Security Center provides monitoring and threat detection, not encryption itself.
- D
Enable double encryption using Azure Key Vault with customer-managed keys and enable Azure Databricks audit logs.
Double encryption provides encryption at rest and in transit; customer-managed keys give control; audit logs track access.
Quick Answer
The correct answer is to enable double encryption using Azure Key Vault with customer-managed keys and enable Azure Databricks audit logs. This combination directly satisfies GDPR requirements for encryption and auditing in Azure Databricks because double encryption provides two layers of protection—server-side encryption using platform-managed keys and an additional layer using customer-managed keys stored in Azure Key Vault—securing data both at rest and in transit, while audit logs capture all access events for compliance reporting. On the DP-203 exam, this scenario tests your understanding of how to layer security controls rather than relying on a single feature; a common trap is choosing Azure Storage Service Encryption alone, which lacks customer-managed key control, or Azure Policy, which enforces rules but does not encrypt data. Remember the memory tip: “Double down on keys, audit the keys to the kingdom”—double encryption with customer-managed keys plus audit logs covers both encryption and access tracking for GDPR.
DP-203 Develop data processing Practice Question
This DP-203 practice question tests your understanding of develop data processing. 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 processing solution for a financial services company. They need to process sensitive customer data in Azure Databricks while complying with GDPR. The data must be encrypted at rest and in transit, and access must be audited. You need to recommend a configuration that meets these requirements. Which combination of actions should you take?
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
Enable double encryption using Azure Key Vault with customer-managed keys and enable Azure Databricks audit logs.
Option B is correct because enabling double encryption and using Azure Key Vault for encryption keys ensures encryption at rest and in transit; Azure Databricks audit logs capture access. Option A (Azure Storage Service Encryption) encrypts at rest but not necessarily with customer-managed keys. Option C (Azure Policy) enforces compliance but does not directly encrypt data. Option D (Azure Security Center) provides monitoring but not encryption.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

- ✗
Enable Azure Storage Service Encryption (SSE) with platform-managed keys and configure Azure Databricks to use a VNet injection.
Why it's wrong here
SSE with platform-managed keys does not give customer control; VNet injection helps with network isolation but not encryption key management.

Why it's wrong here
Security Center provides monitoring and threat detection, not encryption itself.
- ✓

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DP-203 NAT questions on configuration and troubleshooting.
