AI-102 Practice Question: Implement natural language processing solutions
You are building a solution that uses Azure AI Language to analyze customer support transcripts. You need to detect personally identifiable information (PII) and also redact the detected PII from the text. Which TWO features should you use? (Select TWO.)
⚠ Common exam trap
A common mix-up: candidates confuse 'PII detection' with 'PII redaction' as a single feature, or mistakenly think that 'Key phrase extraction' or 'Sentiment analysis' can identify personal data, when in fact only the dedicated PII detection and redaction features handle that task.
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
✓
PII detection
PII detection (Option A) is correct because it is the Azure AI Language feature specifically designed to identify categories of personally identifiable information such as names, addresses, phone numbers, and social security numbers within text. PII redaction (Option D) is correct because it is the companion feature that replaces the detected PII entities with placeholder tokens (e.g., '********') or masks them, enabling safe sharing of transcripts. Together, they fulfill the requirement to both detect and redact PII from customer support transcripts.
