The answer is to register the Azure SQL Database as a data source in Microsoft Purview. This is the foundational step because Microsoft Purview cannot scan or classify data without first establishing a connection to the database through a registered source, which then allows you to run a scan using a configured scan rule set that detects patterns like credit card numbers or social security numbers. On the DP-300 exam, this task tests your understanding of the Purview data governance workflow, often appearing in scenario-based questions where compliance mandates automatic classification—a common trap is assuming classification happens automatically after registration, but the scan itself must be explicitly triggered. Remember the sequence: register first, then scan, then classify; think of it as “register to connect, scan to detect, classify to protect.”
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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 has a compliance requirement to automatically classify and protect sensitive data in Azure SQL Database. You need to configure Microsoft Purview to scan and classify the database. Which THREE actions are required?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run a scan to discover and classify sensitive data.
Option A is correct because running a scan is the primary action that discovers and classifies sensitive data in Azure SQL Database using Microsoft Purview. The scan applies the classification rules from the scan rule set to identify patterns like credit card numbers or social security numbers, and then labels the data accordingly for compliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Run a scan to discover and classify sensitive data.
Why this is correct
The scan performs the classification.

✓
Create a scan rule set that includes the classification rules for sensitive data types.
Why this is correct
A scan rule set defines what to look for.

✓
Register the Azure SQL Database as a data source in Microsoft Purview.
Why this is correct
The data source must be registered.
Related concept
Read the scenario before looking for a memorised answer.
✗
Create a Microsoft Entra ID application and grant it access to the database.
Why it's wrong here
Purview can use managed identity for authentication.
✗
Enable Microsoft Defender for SQL to automatically classify data.
Why it's wrong here
Defender for SQL does not classify data; it provides security alerts.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Defender for SQL's data classification feature (which is a separate, simpler classification) with Microsoft Purview's full scanning and governance pipeline, leading them to incorrectly select Option E as a required action.
Detailed technical explanation
How to think about this question
Under the hood, Purview uses a managed identity or system-assigned identity to authenticate to Azure SQL Database, and the scan rule set defines custom or system classification rules (e.g., regex patterns for sensitive data types). The scan process invokes the Azure SQL Database's built-in classification engine, which can also leverage Microsoft's sensitive information types (SITs) from the Microsoft 365 compliance center, ensuring consistency across data estate.

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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
