AI-102 Practice Question: Implement natural language processing solutions
A company wants to build a solution that can identify and redact personally identifiable information (PII) from customer support transcripts. The solution must handle multiple languages. Which Azure AI service should be used?
⚠ Common exam trap
Candidates often confuse Azure AI Language's PII detection with Azure AI Content Safety, assuming 'safety' includes privacy, but Content Safety addresses content moderation (e.g., toxicity) rather than PII redaction.

Correct answer & explanation
✓
Azure AI Language - PII Detection
Azure AI Language's PII Detection feature is specifically designed to identify and redact personally identifiable information in text across multiple languages. It supports over 30 languages and can detect entities such as names, addresses, phone numbers, and credit card numbers, making it the correct choice for this multilingual PII redaction requirement.
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 AI Content Safety
Why it's wrong here
Azure AI Content Safety classifies harmful content such as violence or hate; it does not identify or redact PII entities. It is tempting as a text-moderation service, but it suits filtering user-generated content, not extracting and masking personal data across languages.
- ✗
Azure AI Document Intelligence
Why it's wrong here
Azure AI Document Intelligence extracts structured data from forms and documents; it does not detect or redact PII within conversational transcripts. It is tempting because it processes text, but it suits invoice, receipt, or form extraction, not multilingual transcript redaction.
- ✗
Azure AI Translator
Why it's wrong here
Azure AI Translator translates text between languages but performs no PII detection or redaction. It is tempting because the scenario demands multilingual handling, yet translation alone leaves personal data intact; it suits localisation, not identifying and masking PII in transcripts.
- ✓
Azure AI Language - PII Detection
Why this is correct
Azure AI Language's PII detection feature natively identifies and redacts personal data across multiple languages, directly satisfying the stem's multilingual requirement. Its prebuilt entity models recognise names, addresses, and phone numbers in transcripts without custom training, unlike translation or vision services that lack redaction capability.
