AWS Certified SysOps Administrator Practice Exam

What can a SysOps Administrator do to help make informed decisions regarding S3 costs?

1. Instantiate new EC2 instances

2. Review the Cost and Usage Report on a monthly basis

3. Limit bucket access permissions

4. Delete older buckets regularly

The correct answer is: Review the Cost and Usage Report on a monthly basis

To make informed decisions regarding S3 costs, reviewing the Cost and Usage Report on a monthly basis is highly effective. This report provides comprehensive insights into your AWS spending, including detailed breakdowns of costs related to Amazon S3. By analyzing this data, a SysOps Administrator can identify usage patterns, detect anomalies, and understand which services or activities contribute most to their AWS bill. This visibility enables proactive cost management and optimization strategies. Other approaches listed, while they might be part of general operations, do not directly aid in understanding or managing costs related to S3. For instance, instantiating new EC2 instances is unrelated to S3 costs, while limiting bucket access permissions mainly focuses on security rather than expense management. Deleting older buckets may save some storage costs, but it does not provide the detailed cost insights necessary for making informed decisions about overall expenditure on S3 services. Therefore, regularly reviewing the Cost and Usage Report stands out as the most effective action for financial oversight related to S3 usage.
