Sample AI-200 Practice Questions
Question 1
In designing a machine learning training pipeline using Azure Machine Learning Workspaces, you need to ensure that your data is stored in a secure and accessible location. Which Azure service should you use to store your training dataset, and how should it be configured to ensure secure access and efficient data loading into the compute cluster?
- Azure Files
- Azure Blob Storage with SAS tokens
- Azure Table Storage
- Azure Queue Storage
The correct answer is to use Azure Blob Storage with SAS (Shared Access Signature) tokens for secure and controlled access. Azure Blob Storage provides a scalable and durable storage solution for large datasets. Using SAS tokens allows you to grant temporary access to specific users or services while maintaining security. Other options like Azure Files or Azure Table Storage may not offer the same level of scalability and performance for large datasets.
Question 2
When setting up a compute cluster for training a machine learning model in Azure Machine Learning Workspaces, which type of compute cluster should you choose if you require high-performance computing resources and want to leverage GPU acceleration for faster training times?
- CPU-only cluster
- Azure Machine Learning Compute Cluster with GPU instances
- Virtual Machine without GPU support
- Azure Batch
The correct answer is to choose an Azure Machine Learning Compute Cluster with GPU instances. This type of compute cluster is specifically designed for high-performance computing tasks and can take advantage of GPU acceleration to speed up training times. Other options like CPU-only clusters or virtual machines without GPU support would not provide the necessary performance for GPU-accelerated training.
Question 3
In an Azure Machine Learning project, you need to optimize the hyperparameters of a machine learning model using HyperDrive. Which of the following best describes how you would set up the HyperDrive configuration to achieve this goal?
- Define a fixed set of hyperparameters and manually run multiple training jobs.
- Define a search space for hyperparameters and configure HyperDrive to perform automated hyperparameter tuning.
- Use a single set of hyperparameters and rely on the model's default settings.
- Create a custom environment container and use it to run training jobs with different hyperparameters.
The correct answer is B because HyperDrive in Azure Machine Learning allows you to define a search space for hyperparameters and automatically runs multiple training jobs with different hyperparameter values to find the optimal set. Option A is incorrect because it refers to a manual process which does not leverage automation. Option C is incorrect as it suggests using a fixed set of hyperparameters, which defeats the purpose of hyperparameter tuning. Option D is incorrect because it mentions a custom environment container, which is not directly related to setting up HyperDrive for hyperparameter tuning.
