AWS Certified Machine Learning Engineer – Associate (MLA-C01) — Question 93

An IoT company uses Amazon SageMaker to train and test an XGBoost model for object detection. ML engineers need to monitor performance metrics when they train the model with variants in hyperparameters. The ML engineers also need to send Short Message Service (SMS) text messages after training is complete.

Which solution will meet these requirements?

Answer options

• A. Use Amazon CloudWatch to monitor performance metrics. Use Amazon Simple Queue Service (Amazon SQS) for message delivery.
• B. Use Amazon CloudWatch to monitor performance metrics. Use Amazon Simple Notification Service (Amazon SNS) for message delivery.
• C. Use AWS CloudTrail to monitor performance metrics. Use Amazon Simple Queue Service (Amazon SQS) for message delivery.
• D. Use AWS CloudTrail to monitor performance metrics. Use Amazon Simple Notification Service (Amazon SNS) for message delivery.

Correct answer: B

Explanation

Option B is correct because Amazon CloudWatch is specifically designed to monitor performance metrics, while Amazon SNS allows for SMS notifications, which meets the requirement for sending messages after training. Options A and C are incorrect because they use Amazon SQS, which is not suitable for sending SMS, and options C and D incorrectly suggest using AWS CloudTrail, which is not intended for performance monitoring.
