DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and 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.
Your organization uses Azure Purview for data governance. You need to automatically scan an Azure Data Lake Storage Gen2 account and classify sensitive data such as credit card numbers and social security numbers. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A new scan rule set in Purview with classification rules for sensitive data types
Option B is correct because Purview's classification rules can detect sensitive data patterns. Option A is wrong because Azure Policy is for resource compliance, not data classification. Option C is wrong because Azure Information Protection (now part of Microsoft Purview Information Protection) labels files but requires integration. Option D is wrong because Microsoft Defender for Cloud is for security posture.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 Information Protection (AIP) scanner
Why it's wrong here
AIP scanner can classify and label files, but it is not integrated with Purview scans for automated classification.
✗
Microsoft Defender for Cloud
Why it's wrong here
Defender for Cloud provides security recommendations and threat detection, not data classification.
✓
A new scan rule set in Purview with classification rules for sensitive data types
Why this is correct
Purview can create custom scan rule sets that include classification rules to detect sensitive data during scans.
Related concept
Static NAT maps one inside address to one outside address.
✗
Azure Policy with built-in guest configuration
Why it's wrong here
Azure Policy enforces rules on resource configurations, not data classification.
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.
