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. 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. A key principle to apply: language Detection is a pre-built Azure AI Language feature.. 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 global company receives customer support tickets in over 60 languages. They need to automatically detect the language of each ticket so it can be routed to the appropriate language-specific team. The company has no labeled training data for language identification. Which Azure AI Language feature should they use?
Why wrong: Custom Text Classification requires labeled training data and is used to classify text into custom categories, not to detect language.
B
Language Detection
Language Detection is a pre-built capability that identifies the language of text without needing custom training data. It supports many languages and is ideal for this scenario.
C
Key Phrase Extraction
Why wrong: Key Phrase Extraction identifies important phrases in text but does not detect language.
D
Entity Recognition
Why wrong: Entity Recognition identifies named entities (people, places, etc.) but does not detect the language of the text.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Language Detection
Language Detection is the correct choice because it is a pre-built, zero-shot Azure AI Language feature that can automatically identify the language of text without requiring any labeled training data. The service uses a multilingual model trained on large datasets to detect over 100 languages, making it ideal for routing support tickets in over 60 languages with no prior customization.
Key principle: Language Detection is a pre-built Azure AI Language feature.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates might confuse Language Detection with Custom Text Classification, assuming they need to train a model for a multilingual scenario, when in fact Azure provides a built-in, no-code language detection API that requires zero training data.

Detailed technical explanation
How to think about this question
Under the hood, Azure Language Detection uses a deep neural network trained on the Unicode Common Locale Data Repository (CLDR) and other multilingual corpora, returning a language name, ISO 639-1 code, and a confidence score. A subtle behavior is that for very short text (e.g., a single word), the service may return 'Unknown' or a lower confidence score, so real-world implementations often concatenate multiple sentences from a ticket for more reliable detection.
KKey Concepts to Remember
Language Detection is a pre-built Azure AI Language feature.
It requires no custom training data or model development.
It identifies the primary language of text and returns a language code and confidence score.
It supports a wide range of languages out-of-the-box.
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
Language Detection is a pre-built Azure AI Language feature.
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. Language Detection is a pre-built Azure AI Language feature. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
