Question #902
Which strategies exemplify a company’s approach to rightsizing its AWS infrastructure to optimize cloud expenditures? (Choose two.)
Implement AWS Auto Scaling to dynamically adjust EC2 instance capacity based on real-time demand.
Migrate rarely accessed data from Amazon S3 to Amazon S3 Glacier Deep Archive.
Deploy Amazon RDS Read Replicas to enhance database read performance.
Purchase Scheduled Reserved Instances for EC2 instances with predictable usage patterns.
Set up AWS Direct Connect to establish a dedicated network connection.
Explanation
A (AWS Auto Scaling) allows dynamic adjustment of EC2 instances based on demand, ensuring optimal resource usage and cost efficiency. B (migrating to S3 Glacier Deep Archive) reduces storage costs for rarely accessed data, aligning storage tiers with access patterns.
C (RDS Read Replicas) improves read performance but does not directly reduce costs or adjust resource sizing. D (Scheduled Reserved Instances) saves costs via pricing models but does not 'rightsize' resources. E (Direct Connect) optimizes network performance, not resource sizing. Rightsizing focuses on matching resource capacity to actual needs, making A and B the best answers.
Answer
The correct answer is: AB
