You are configuring a machine learning model for deployment. What should you prioritize?
AModel Complexity
BModel Explainability
CModel Training Time
DModel Size
Explanation
Model explainability is essential for trust and transparency, more so than other factors here.
Q52
Which Azure service is best suited for real-time streaming analytics?
AAzure Functions
BAzure Cosmos DB
CAzure Stream Analytics
DAzure Firestore
Explanation
Azure Stream Analytics specializes in real-time data processing, while the others serve different purposes such as serverless computing or database services.
Q53
A company needs to manage their data science project lifecycle effectively. What should they use?
AAzure Notebooks
BAzure DevOps
CAzure Machine Learning Workspaces
DAzure Data Lake Storage
Explanation
Azure DevOps provides tools for managing the entire project lifecycle, whereas the others focus on specific aspects like code or storage.
Q54
You are configuring an Azure Machine Learning model for deployment. What happens when you select 'Real-time endpoint'?
ABatch processing deployed
BScalable endpoint for predictions
CData is automatically cleaned
DModel will run only on-premises
Explanation
Selecting 'Real-time endpoint' creates a scalable REST endpoint for instant predictions, not batch processing or other options.
Q55
Which Azure service is best for real-time event processing?
AAzure Stream Analytics
BAzure Blob Storage
CAzure SQL Database
DAzure Virtual Machine
Explanation
Azure Stream Analytics specifically handles real-time data streams, while other options are not designed for real-time processing.
Q56
A company needs to implement a secure REST API for their data science models. Which Azure service should they use?
AAzure API Management
BAzure Data Lake Storage
CAzure Functions
DAzure DevOps
Explanation
Azure API Management allows for secure APIs, while the other options do not focus on API management functionalities.
Q57
What happens when you set the 'warm-up' time for an Azure Machine Learning model deployment?
AModel loads faster initially
BRequests get throttled
CModel is not ready for requests
DIncreased cost from idle time
Explanation
Setting 'warm-up' time delays readiness for requests, ensuring the model is fully prepared before handling them.
Q58
Which Azure service is best for real-time analytics on streaming data?
AAzure Stream Analytics
BAzure Blob Storage
CAzure SQL Database
DAzure Data Lake Storage
Explanation
Azure Stream Analytics provides real-time insights, while others are not optimized for streaming data.
Q59
A company needs to scale its machine learning model on-demand. Which Azure service should they use?
AAzure Functions
BAzure Machine Learning
CAzure Batch
DAzure App Service
Explanation
Azure Machine Learning supports model deployment and scaling, whereas others do not specialize in ML models.
Q60
What happens when you configure a model with high bias in Azure ML?
AModel underfits training data
BModel overfits training data
CModel performs excellently
DModel ignores all input features
Explanation
High bias leads to underfitting, while other options describe different types of model behavior.
