You are configuring a model training pipeline in Azure. What happens if you set the maximum number of concurrent pipelines to zero?
AAll pipelines will execute immediately
BNo pipelines will execute
CThe system will default to one pipe
DPipelines will queue indefinitely
Explanation
Setting concurrency to zero effectively halts all pipeline executions, unlike other options.
Q22
Which Azure service is best suited for building machine learning models?
AAzure Machine Learning
BAzure Data Factory
CAzure Databricks
DAzure Logic Apps
Explanation
Azure Machine Learning is specifically designed for building, training, and deploying machine learning models, while the others serve different purposes.
Q23
A company needs to deploy a predictive model for real-time user data. What Azure solution should they use?
AAzure Batch
BAzure Stream Analytics
CAzure Blob Storage
DAzure Logic Apps
Explanation
Azure Stream Analytics enables real-time data processing, which is critical for predictive modeling on live data.
Q24
You are configuring an Azure ML workspace. What happens if you set the default compute target to VM with limited GPUs?
AOnly CPU processing will be allowed.
BAll models will fail to run.
CGPU models will run slower.
DTraining will only use CPU.
Explanation
Setting the compute target to a limited GPU VM means models that utilize GPUs will still run but potentially with reduced performance.
Q25
Which Azure service is primarily used for building, training, and deploying machine learning models?
AAzure Machine Learning
BAzure Data Factory
CAzure Databricks
DAzure Synapse Analytics
Explanation
Azure Machine Learning is specifically designed for machine learning workflows, while the others serve different data processing purposes.
Q26
A company needs to implement version control for their machine learning models. What service should they choose?
AAzure DevOps
BAzure Blob Storage
CAzure Data Lake Storage
DAzure Cognitive Services
Explanation
Azure DevOps provides tools for version control while the others do not focus on model versioning.
Q27
What happens when you try to deploy a model with mismatched schema in Azure Machine Learning?
ADeployment succeeds with warnings
BDeployment fails
CModel runs but gives errors
DSchema automatically adjusts
Explanation
Deployment fails due to the mismatch in expected input schema.
Q28
Which Azure service would you use for real-time data processing?
AAzure Stream Analytics
BAzure Blob Storage
CAzure Data Lake Storage
DAzure SQL Database
Explanation
Azure Stream Analytics is optimized for real-time data processing, while the others are focused on storage solutions or batch processing.
Q29
A company needs to automate model deployment in Azure. Which service should they use?
AAzure DevOps
BAzure Machine Learning
CAzure Functions
DAzure Virtual Machines
Explanation
Azure Machine Learning provides built-in capabilities for automating model deployment, while Azure DevOps focuses on workflow management and CI/CD practices.
Q30
What happens when you don't set an expiration for a dataset in Azure Data Lake Storage?
AData is deleted automatically
BData remains indefinitely
CData becomes read-only
DData triggers alerts
Explanation
If no expiration is set, the data stays in Azure Data Lake Storage indefinitely until explicitly deleted by the user.
