AI-102 Practice Question: Implement natural language processing solutions
Your organization uses Azure AI Language to analyze customer support tickets. You need to ensure that personally identifiable information (PII) is detected and redacted before further processing. Which TWO features should you use?
⚠ Common exam trap
This question tests the distinction between detection and redaction, where candidates mistakenly think that simply detecting PII (Option C) satisfies the requirement to 'ensure PII is redacted,' but the question explicitly requires both detection and redaction, making Option B necessary alongside Option C.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Redaction
Redaction (Option B) is correct because it is the process of masking or removing detected PII from text, which directly meets the requirement to ensure PII is redacted before further processing. Azure AI Language provides a dedicated PII detection and redaction feature that identifies categories such as names, phone numbers, and credit card numbers, and then replaces them with placeholders like '********' or entity type labels.

Entity linking
Why it's wrong here
Entity linking links mentions to knowledge bases, not PII detection.

Redaction removes or masks the detected PII.
- ✓
PII detection
Why this is correct
PII detection specifically identifies personal information.
