AWS Certified AI Practitioner AIF-C01 Practice Question
A team hosts a generative AI model on an Amazon SageMaker real-time endpoint that currently runs on one ml.g5.xlarge instance in a single Availability Zone. To improve availability without greatly increasing monthly spend, which action is the MOST cost-effective choice?
Replace the ml.g5.xlarge with a larger instance class in the same Availability Zone.
Enable SageMaker data capture and store invocations in Amazon S3.
Increase the endpoint's instance count to two of the same instance type.
Deploy an identical endpoint in a second AWS Region and use Amazon Route 53 latency-based routing.
Running the endpoint on two instances allows SageMaker to place the instances in separate Availability Zones. This provides resilience if one AZ becomes unavailable, yet only doubles the instance cost compared with more expensive alternatives such as multi-Region duplication or larger instance types. Merely replacing the instance with a larger size does not add fault tolerance, and SageMaker data capture is unrelated to availability.
