- A
Key Phrase Extraction
Why wrong: Key Phrase Extraction identifies important words and phrases in general text, but it is not specialized for medical terminology and does not provide the structured medical entity recognition needed.
- B
Named Entity Recognition (NER)
Why wrong: Standard NER can identify general categories like person, location, and organization, but it is not pre-trained with medical-specific entities like diseases or medications.
- C
Text Analytics for Health (Healthcare NLP)
This prebuilt Azure AI Language feature is trained on medical literature and clinical data, enabling extraction of medical entities, relationships, and assertions without custom training.
- D
Sentiment Analysis
Why wrong: Sentiment Analysis determines whether text is positive, negative, or neutral, not for extracting medical entities.
Quick Answer
The correct answer is Text Analytics for Health (Healthcare NLP), a pre-trained Azure AI Language feature that extracts medical terms like disease names, symptoms, and medications from unstructured clinical text without requiring any custom training. This service is built on medical ontologies such as UMLS and SNOMED CT, allowing it to recognize complex healthcare entities directly from clinical trial reports or patient records. On the AI-900 exam, this question tests your understanding of Azure’s specialized, pre-built AI services versus custom machine learning solutions—a common trap is confusing Text Analytics for Health with the general Custom Text Classification or Entity Recognition, which do require labeled training data. Remember that “for Health” signals a domain-specific, out-of-the-box capability. A useful memory tip: think of “Health” as the keyword that means “no training needed—just plug in clinical text and extract.”
AI-900 Practice Question: Describe features of Natural Language Processing workloads on Azure
This AI-900 practice question tests your understanding of describe features of natural language processing workloads on azure. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A medical research team needs to analyze thousands of clinical trial reports to extract specific medical terms like disease names, symptoms, and medications. They want to use an Azure AI Language feature that is pre-trained on medical data and requires no custom training. Which feature should they use?
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
Text Analytics for Health (Healthcare NLP)
Option C is correct because Text Analytics for Health (Healthcare NLP) is a pre-trained Azure AI Language feature specifically designed to extract medical entities such as disease names, symptoms, medications, and treatment details from unstructured clinical text. It requires no custom training and is built on medical ontologies like UMLS, making it ideal for analyzing thousands of clinical trial reports without additional model development.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse generic Named Entity Recognition (NER) with domain-specific healthcare NER, assuming any NER can handle medical terms, but only Text Analytics for Health is pre-trained on medical data and requires no custom training.

Detailed technical explanation
How to think about this question
Text Analytics for Health leverages a deep learning model trained on large biomedical corpora and integrates with the Unified Medical Language System (UMLS) to map extracted entities to standardized concept IDs. It also supports relation extraction (e.g., linking a medication to a dosage) and negation detection (e.g., 'no evidence of infection'), which are critical for accurate clinical data analysis. In real-world scenarios, this feature can process thousands of clinical trial reports in batch mode via the Azure AI Language API, returning structured JSON output with entity categories, confidence scores, and offsets.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
