SAP-C02 Question 568
Select 4An organization is planning to migrate its on-premises infrastructure to AWS. The current infrastructure includes a mix of compute, storage, and database resources, with some assets running continuously and others being used only during business hours. The organization wants to optimize cost while ensuring that resources are available when needed. Which of the following strategies should the organization implement as part of their asset planning on AWS?
- A
Use Auto Scaling groups for dynamic adjustment of compute resources based on demand.
- B
Implement Amazon EC2 Reserved Instances for workloads that run continuously.
- C
Use Amazon S3 Intelligent-Tiering for storage to optimize costs based on access patterns.
- D
Manually start and stop instances for workloads used only during business hours to save costs.
- E
Leverage AWS Savings Plans for flexible pricing across compute services.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Effective asset planning on AWS involves leveraging built-in services and tools that automate resource scaling, optimize costs, and match resources to usage patterns. Auto Scaling, Reserved Instances, S3 Intelligent-Tiering, and Savings Plans all contribute to a well-architected and cost-effective solution. Manual interventions, like starting and stopping instances, are not efficient for asset planning as they do not scale and can introduce human error.
- A. Correct.
Using Auto Scaling groups allows the organization to dynamically adjust compute capacity based on demand, ensuring cost optimization and resource availability when needed.
- B. Correct.
Amazon EC2 Reserved Instances provide significant cost savings for workloads that run continuously, making it a suitable choice for this scenario.
- C. Correct.
Amazon S3 Intelligent-Tiering automatically moves data between storage tiers based on access patterns, optimizing storage costs without manual intervention.
- D. Incorrect.
Manually starting and stopping instances is not an efficient or scalable solution for asset planning. AWS provides tools like Auto Scaling and scheduling to automate these tasks.
- E. Correct.
AWS Savings Plans offer flexible pricing for compute services and are an effective way to manage and reduce costs across various AWS services.
