3 questions from the free diagnostic, with answers and explanations.

Question 1 · Create and manage resources in a Machine Learning workspace

Which Azure Machine Learning compute scales out to several nodes for training jobs and back down to zero nodes when it is idle?

  1. A compute cluster with a minimum of 0 nodes
  2. A compute instance with idle shutdown turned on
  3. Serverless Spark compute attached to the workspace
  4. An attached Kubernetes cluster with a fixed node pool
Show answer

Answer: A (A compute cluster with a minimum of 0 nodes)

Compute clusters autoscale between the minimum and maximum node counts; a minimum of 0 means you pay nothing when no jobs run. Compute instances are single development machines.

Question 2 · Orchestrate model training

Which Azure Machine Learning feature chains data preparation, training and evaluation as reusable steps that can run on different compute?

  1. Pipelines built from components
  2. Automated ML (AutoML) jobs
  3. A sweep job over several scripts
  4. Registered environments
Show answer

Answer: A (Pipelines built from components)

Pipelines connect components (reusable, versioned steps) into a workflow; each step can run on its own compute and be reused.

Question 3 · Implement Foundry environments and platform configuration

In Microsoft Foundry, which item groups one application's models, agents, evaluations, data and connections so a team can work on it?

  1. A Foundry project
  2. A Foundry hub resource
  3. A resource group
  4. A connection
Show answer

Answer: A (A Foundry project)

Projects are the work areas inside a Foundry resource where teams build, evaluate and deploy an app.

AI-300 practice test FAQ

Is there a free AI-300 practice test?

Yes. Create a free account and take the AI-300 free diagnostic: 10 questions across every skill area of the exam, with a study plan for the topics to work on. You can retake it as often as you like.

How many questions are in each ExamKite AI-300 practice test?

Each full practice test has 40 questions with a 100-minute timer, and you pass at 70%. There are 6 practice tests plus a harder challenge test, with 350 questions in total.

Which question formats does the AI-300 practice include?

Single choice, hotspot (drop-down and yes/no), case studies and exhibits (screenshots, diagrams and code), the same formats you meet on the real exam.

Are these real AI-300 exam questions?

No. They are original questions written for ExamKite and mapped to the Microsoft skills outline, never copied from the real exam. Using leaked exam questions breaks the certification provider's exam rules and can get your certification revoked.
