Question 934 of 945
AI-102 Practice Question: Implement natural language processing solutions
You are building a multilingual chatbot using Azure AI Language. The chatbot must handle English, Spanish, and French. You need to configure the LUIS (Language Understanding) model to support multiple languages efficiently. What is the best practice?
⚠ Common exam trap
It's easy for candidates to assume a 'Multilingual' setting or a single app with mixed utterances is supported, but LUIS requires separate apps per language for custom models, and the 'Multilingual' option only applies to prebuilt domains.
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
✓
Create a separate LUIS app for each language and use the same intents and entities structure.
LUIS does not support a single multilingual model; each LUIS app is designed for a single primary language. To handle multiple languages efficiently, you must create a separate LUIS app per language, each with the same intent and entity schema, and route user queries to the appropriate app based on the detected language. This ensures optimal language-specific model training and accuracy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the prebuilt multilingual LUIS model and fine-tune it with your intents.
Why it's wrong here
There is no prebuilt multilingual LUIS model; LUIS requires training per language.
- ✓
Create a separate LUIS app for each language and use the same intents and entities structure.
Why this is correct
Each language requires its own app with utterances in that language.
- ✗
Create a single LUIS app and add utterances in all three languages.
Why it's wrong here
LUIS apps are language-specific; mixing languages will degrade accuracy.
- ✗
Create one LUIS app with language set to 'Multilingual' and add utterances in all languages.
Why it's wrong here
LUIS does not support a 'Multilingual' option; you must create separate apps.
