AI-102 Practice Question: Implement knowledge mining and information extraction solutions
You are using Microsoft Purview to create a knowledge map of your organization's data assets. The solution must automatically scan and classify sensitive data in Azure Blob Storage. You need to configure the scanning and classification. Which THREE actions should you perform?
⚠ Common exam trap
Candidates often confuse the required actions for configuring scanning (registering the source, creating a scan rule set, and running a scan) with optional or subsequent steps like creating custom rules or applying sensitivity labels, leading them to select B or C instead of the correct three.
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
✓
Run a full scan of the Blob Storage to discover and classify data.
Running a full scan of Azure Blob Storage in Microsoft Purview is the mechanism that discovers and classifies sensitive data. A full scan examines all files and metadata, applying the configured classification rules to identify sensitive information types such as credit card numbers or social security numbers. This action is essential for populating the knowledge map with classified data assets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Run a full scan of the Blob Storage to discover and classify data.
Why this is correct
Scanning is required to apply classifiers.
- ✗
Create custom classification rules for sensitive data types.
Why it's wrong here
Built-in classifiers may suffice; custom rules are optional.
- ✗
Apply sensitivity labels to the classified data.
Why it's wrong here
Sensitivity labeling is separate from scanning.
- ✓
Create a scan rule set that includes the desired classification rules.
Why this is correct
Scan rule sets define what classifiers to apply.
- ✓
Register the Azure Blob Storage account as a data source in Purview.
Why this is correct
Required to scan the storage.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
