The correct answer is to deploy the custom text classification model to a real-time endpoint and use the correct endpoint URL and key for authentication. A real-time endpoint is specifically designed for low-latency REST API access, as it keeps the model loaded and ready to process individual requests instantly, unlike batch processing which queues jobs and introduces significant delay. On the Microsoft Azure AI Engineer Associate AI-102 exam, this scenario tests your understanding of Azure AI Language deployment options, where the common trap is confusing batch processing with real-time inference or assuming a “test” endpoint exists for production use. Remember that for any REST API requiring sub-second responses, you must deploy to a real-time endpoint—batch is for offline analysis, and the only valid endpoints are “real-time” or “serverless” (for pay-per-call). A useful memory tip: “Real-time for REST, batch for backlog.”
AI-102 Practice Question: Implement natural language processing solutions
This AI-102 practice question tests your understanding of implement natural language processing solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 developer is deploying a custom text classification model in Azure AI Language. The model must be accessible via a REST API with low latency. Which TWO actions should the developer take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Obtain the endpoint URL and primary key from Language Studio
Options A and C are correct. Deploying the model as a real-time endpoint is required for low-latency REST API access. Using the correct endpoint and key is also necessary. Option B is wrong because batch processing is not low-latency. Option D is wrong because a 'test' endpoint does not exist. Option E is wrong because export/import is not needed for deployment.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
