Which Azure service offers a fully managed NoSQL database?
AAzure Cosmos DB
BAzure SQL Database
CAzure Blob Storage
DAzure Data Lake Storage
Explanation
Azure Cosmos DB provides globally distributed NoSQL databases, whereas the others serve different storage functionalities.
Q92
A company needs to deploy machine learning models. What should they use?
AAzure Synapse Analytics
BAzure Machine Learning
CAzure Functions
DAzure Data Factory
Explanation
Azure Machine Learning is designed specifically for building and deploying ML models, unlike the other options.
Q93
What happens when you configure auto-scaling in Azure Machine Learning?
AIncreases storage capacity.
BAutomatically scales compute resources.
CLimits model functionality.
DDecreases training speed.
Explanation
Auto-scaling adjusts compute resources based on demand, while other options do not accurately describe scaling behavior.
Q94
You are configuring Azure Machine Learning. Which language is supported for scripting custom models?
APython
BRuby
CSwift
DGo
Explanation
Python is the primary language for Azure ML, while Ruby, Swift, and Go are not supported.
Q95
A company needs to deploy a machine learning model that handles sensitive customer data. Which Azure service provides built-in security features for such workloads?
AAzure Blob Storage
BAzure Machine Learning
CAzure Functions
DAzure Data Factory
Explanation
Azure Machine Learning includes compliance features for handling sensitive data, unlike Blob Storage, Functions, and Data Factory.
Q96
What happens when you select a lower `max_distance` in a KMeans clustering scenario in Azure ML?
AMore clusters created
BLess data is included
CIncreased complexity of model
DFewer iterations run
Explanation
A lower `max_distance` can lead to more clusters being formed, while the other options are incorrect interpretations of the parameter's effect.
Q97
Which service can be used to automate ML model deployment?
AAzure ML
BAzure Functions
CAzure SQL Database
DAzure Blob Storage
Explanation
Azure ML provides tools for deploying models, while the others serve different purposes.
Q98
A company needs to streamline data preprocessing for ML. Which Azure service is best suited for ETL tasks?
AAzure Data Factory
BAzure Logic Apps
CAzure DevOps
DAzure Kubernetes Service
Explanation
Azure Data Factory specializes in ELT processes, unlike the other options.
Q99
What happens when you set a model's input without matching the trained schema in Azure ML?
AIt will throw an error.
BIt will auto-correct the schema.
CIt will process with default values.
DIt will return incorrect predictions.
Explanation
Mismatched inputs lead to schema validation errors during model execution.
Q100
Which service is optimal for real-time analytics on streaming data?
AAzure Stream Analytics
BAzure Data Lake
CAzure SQL Database
DAzure Blob Storage
Explanation
Azure Stream Analytics is designed for real-time data analysis; the others are for different storage or processing tasks.
