B. They act as an entry point for routing requests to the deployed model
C. They train the model in real-time
D. They visualize model performance metrics

Answer: B
Explanation: API gateways manage and route external requests to the appropriate backend services, including deployed models, while handling authentication and rate limiting.

Question 8:
In Kubernetes, what is a pod used for in model deployment?
A. To manage user access
B. To deploy and run containers as a group
C. To store historical data
D. To debug code errors

Answer: B
Explanation: A Kubernetes pod is the smallest deployable unit that can contain one or more containers, making it ideal for orchestrating and scaling deployed machine learning models.

Question 9:
Why is versioning important in model deployment?
A. It allows models to be trained faster
B. It tracks changes and enables rollback to previous versions if issues arise
C. It reduces the need for testing
D. It automatically deletes old models

Answer: B
Explanation: Versioning helps manage updates to models, allowing teams to revert to a stable version if a new deployment introduces bugs or performance issues.

Question 10:
Which security practice is essential when deploying a machine learning model?
A. Exposing all endpoints publicly
B. Implementing encryption for data in transit
C. Avoiding authentication mechanisms
D. Sharing API keys openly

Answer: B
Explanation: Encryption ensures that data sent to and from the deployed model is protected from unauthorized access, maintaining confidentiality and compliance.

Question 11:
What is A/B testing in the context of model deployment?
A. Testing a model against a benchmark dataset
B. Comparing two versions of a model with live traffic to determine performance
C. Deploying a model on multiple servers
D. Auditing the model’s code for errors

Answer: B
Explanation: A/B testing involves serving different model versions to subsets of users to evaluate which performs better in real-world scenarios, aiding in informed deployment decisions.

Question 12:
Which metric is commonly monitored after model deployment to ensure reliability?
A. Training accuracy
B. Latency and throughput
C. Model architecture size
D. Dataset size

Answer: B
Explanation: Monitoring latency (response time) and throughput (requests per second) helps assess how well the deployed model handles production loads and maintains performance.

Question 13:
What is the purpose of a model’s inference endpoint?
A. To retrain the model with new data
B. To provide an interface for making predictions with the deployed model
C. To store the model’s weights
D. To visualize training progress

Answer: B
Explanation: An inference endpoint is a URL or service that accepts input data and returns predictions from the deployed model, facilitating real-time or batch inference.

Question 14:
In model deployment, what does “blue-green deployment” refer to?
A. Deploying models only in blue environments
B. Switching traffic between two identical environments to minimize downtime
C. Using green energy for servers
D. Deploying models in a single color-coded phase

Answer: B
Explanation: Blue-green deployment involves running two environments (blue and green) simultaneously, allowing traffic to switch seamlessly to the new version, reducing risks during updates.

Question 15:
Why might you use edge deployment for a machine learning model?
A. To increase data center costs
B. To process data closer to the source for reduced latency
C. To centralize all computations
D. To avoid using any cloud services

Answer: B
Explanation: Edge deployment places models on devices near the data source, such as IoT devices, enabling faster processing and reducing the need for data transmission to central servers.

Question 16:
Which format is commonly used for serializing machine learning models for deployment?
A. CSV
B. JSON
C. Pickle or ONNX
D. TXT

Answer: C
Explanation: Formats like Pickle (for Python) or ONNX allow models to be saved and loaded efficiently, preserving their structure and weights for deployment across different environments.

Question 17:
What challenge does model drift pose in deployed models?
A. It improves model accuracy over time
B. It causes the model’s performance to degrade as data changes
C. It speeds up deployment processes
D. It eliminates the need for monitoring

Answer: B
Explanation: Model drift occurs when the real-world data diverges from the training data, leading to decreased accuracy, which requires monitoring and potential retraining.
