AI-901 practice test questions

Question 1: Which statement best describes artificial intelligence in a business application?

The correct answer is A capability that allows software to perform tasks that normally require human intelligence.

Artificial intelligence helps applications recognize patterns, understand language, make predictions, generate content, or support decisions. It is not limited to one Azure service or one type of workload. In business scenarios, AI is used to automate and improve tasks that previously required human reasoning or perception.

Question 2: Which AI workload is most appropriate for predicting whether a customer will renew a subscription?

The correct answer is Classification.

Classification predicts a category or class, such as renew or not renew, approved or rejected, and high risk or low risk. It is different from regression, which predicts numeric values. Subscription renewal prediction is a typical classification scenario because the output is a discrete label.
