Quick Answer
The answer is the 'to' parameter. In the Azure AI Translator REST API, the 'to' parameter is the required query string that specifies the target language for the translation output, such as 'fr' for French, 'de' for German, or 'es' for Spanish. This parameter directly maps to the destination language you want the source text converted into, and it can be used multiple times in a single request to translate into several languages at once. On the Microsoft Azure AI Engineer Associate AI-102 exam, this concept tests your understanding of the Translator API's request structure, and a common trap is confusing 'to' with 'from' (which sets the source language) or inventing a parameter like 'targetLanguage'—neither of which exists in the API specification. To remember it easily, think of the phrase "translate TO a language, not FROM it," and note that the parameter is just two letters: 'to'.
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 building a multilingual translation solution using Azure AI Translator. The solution must translate text to French, German, and Spanish. Which parameter should the developer set to specify the target language?
language
Why wrong: 'language' is not a REST API parameter.
to
'to' specifies target language.
targetLanguage
Why wrong: 'targetLanguage' is not the correct parameter name.
from
Why wrong: 'from' specifies source language.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
to
Option B is correct because the 'to' parameter specifies the target language. Option A is wrong because 'from' specifies source language. Option C is wrong because 'language' is not a REST API parameter. Option D is wrong because 'targetLanguage' is not the correct parameter name.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
