Question 1

Which Azure OpenAI parameter controls how deterministic or random the model's output is during text generation?

Accepted Answer

temperature

Answer

Temperature scales the probability distribution over tokens; lower values make output more deterministic, higher values increase randomness.

Question 2

A company needs real-time speech transcription with speaker diarization in a call center application. Which Azure service should they use?

Accepted Answer

Azure AI Speech with conversation transcription

Answer

Azure AI Speech's conversation transcription feature provides real-time multi-speaker diarization that identifies and labels each speaker's segments.

Question 3

What is the key advantage of using Azure OpenAI's function calling feature in an agent application?

Accepted Answer

It enables the model to output structured JSON to invoke defined functions reliably

Answer

Function calling lets you define schemas for external functions and the model returns structured JSON arguments, enabling reliable tool use in agents.

Question 4

In Azure AI Search, what does the 'semantic ranker' do differently from standard BM25 ranking?

Accepted Answer

It re-ranks BM25 results using language model-based semantic understanding

Answer

Semantic ranker applies a cross-encoder model to re-score top BM25 candidates based on deeper semantic relevance to the query.

Question 5

Which Azure Machine Learning feature automatically explores multiple algorithms and hyperparameters to find the best model for a given dataset?

Accepted Answer

Automated ML (AutoML)

Answer

AutoML iterates through algorithm and hyperparameter combinations, evaluating each against a specified primary metric to surface the best candidate model.
