Sample questions
A few questions from this practice exam, with the correct answer and why it is correct.
1.A training workload fine-tunes a deep learning model on images. Which Azure Machine Learning compute specification is most appropriate?
- AA managed online endpoint
- BA serverless Spark pool
- CA CPU-only compute instance
- DA GPU-enabled compute clusterCorrect answer
Why
Deep learning on images benefits from GPU acceleration, so a GPU-enabled compute cluster such as an NC or ND series virtual machine size is the appropriate choice.
2.Which Azure Machine Learning compute type is a single-user development machine for running notebooks interactively?
- AA compute cluster
- BA compute instanceCorrect answer
- CAn attached Kubernetes cluster
- DA batch endpoint
Why
A compute instance is a managed virtual machine bound to one user for interactive work. A compute cluster scales out for jobs and is shared across the workspace.
3.Which Azure Machine Learning compute target automatically scales to zero nodes when no jobs are queued?
- AA compute cluster with minimum nodes set to zeroCorrect answer
- BA managed online endpoint
- CAn attached Synapse Spark pool
- DA compute instance
Why
A compute cluster is configured with a minimum and maximum node count, and setting the minimum to zero means it releases all nodes when idle, so nothing is billed.
4.A team wants to build a model without writing code, using a drag-and-drop canvas. Which Azure Machine Learning development approach fits?
- AAn MLflow project
- BThe Azure CLI with YAML job specs
- CThe Azure Machine Learning designerCorrect answer
- DThe Python SDK v2
Why
The designer provides a visual pipeline canvas with prebuilt components. Automated machine learning also requires no code but explores algorithms rather than letting the user compose a pipeline.
5.Which Azure Machine Learning data asset type should be registered for a single CSV file used as a training input?
- Amltable
- Bcustom_model
- Curi_folder
- Duri_fileCorrect answer
Why
A uri_file asset points at one file. uri_folder points at a directory, and mltable carries a schema definition for tabular data that needs transformation on load.
