   A company runs a real-time inference endpoint for a recommendation model. The traffic pattern is predictable: high during business hours and low at night. The team wants to reduce costs without sacrificing performance during peak hours. The model is deployed on a SageMaker endpoint with a single instance. What should the team do?

   • AMove the endpoint to AWS Lambda for serverless inference.
   • BUse Spot Instances for the endpoint to reduce cost.
   • CUse a larger instance type to handle peak traffic and keep it running 24/7.
   • DConfigure automatic scaling based on a schedule to scale out during business hours and scale in at night.

   A team is running a SageMaker training job and wants to monitor the progress of the job. The team wants to be alerted if the job fails or if the training loss is not decreasing as expected. What should the team do?

   • AUse AWS CloudTrail to monitor API calls to the training job.
   • BUse SageMaker Debugger to monitor training metrics and create a CloudWatch alarm on the loss metric.
   • CUse CloudWatch alarms on the CPUUtilization metric of the training instances.
   • DUse SageMaker Model Monitor to monitor the training data for drift.

   A data science team runs nightly training jobs on a SageMaker training cluster. The finance department wants to track and control the monthly spend on these jobs. The team needs to be alerted when the projected monthly cost exceeds a threshold, and they also want a detailed breakdown of costs by training job and instance type. What should the team do?

   • AEnable detailed billing reports and use Amazon QuickSight to visualize costs, then set a billing alarm in CloudWatch.
   • BEnable AWS Cost and Usage Report (CUR) and use Amazon Athena to query the report for cost breakdowns, and create a budget in AWS Budgets for alerts.
   • CCreate a budget in AWS Budgets with a cost threshold and a CloudWatch alarm that sends an email when the budget forecast exceeds the threshold.
   • DUse AWS Cost Explorer to view the cost breakdown and create a CloudWatch alarm on the estimated monthly charge metric.

   A company uses SageMaker to run training jobs and host endpoints. The finance team wants to allocate costs to different departments. The team has already tagged all SageMaker resources with a 'department' tag. What should the team do to see the cost breakdown by department?

   • AUse AWS Cost Explorer to filter costs by the 'department' tag.
   • BUse AWS Trusted Advisor to view cost optimization recommendations.
   • CUse AWS Budgets to create a budget for each department.
   • DUse Amazon CloudWatch to view the billing metrics for each department.
