SAP-C02 Question 567
Select 2A company is planning to migrate its on-premises infrastructure to AWS. The workload consists of a mix of compute, storage, and database resources. The company has a strict budget and needs to ensure cost efficiency while maintaining performance and scalability. As a Solutions Architect, how would you approach asset planning for this migration?
- A
Use AWS Migration Hub to track the progress of resource migrations and estimate costs.
- B
Right-size instances by analyzing the on-premises usage patterns and selecting the appropriate EC2 instance types.
- C
Use Reserved Instances for all compute resources to guarantee cost efficiency.
- D
Leverage Amazon S3 for storing archival data and enable lifecycle policies to move data to lower-cost storage tiers.
- E
Implement a hybrid architecture by keeping all critical workloads on-premises and only migrating non-critical workloads to AWS.
Show answer and explanation
Correct answers: B, D
Explanation
Asset planning during a migration involves identifying the most cost-efficient and scalable options for each workload. Right-sizing instances ensures proper resource allocation without over-provisioning, while using Amazon S3 with lifecycle policies helps reduce storage costs for less frequently accessed data. These practices align with cost efficiency and scalability requirements, making them the most appropriate choices for this scenario.
- A. Incorrect.
AWS Migration Hub is a useful tool for tracking migration progress, but it does not directly contribute to cost efficiency or asset planning during a migration.
- B. Correct.
Right-sizing instances ensures that resources are provisioned in a cost-effective manner while maintaining the required performance. This is a critical step in asset planning.
- C. Incorrect.
Reserved Instances can be cost-effective, but committing to them before fully understanding workload patterns can lead to inefficiencies. Using Savings Plans or Spot Instances might be more flexible.
- D. Correct.
Leveraging Amazon S3 with lifecycle policies is a cost-efficient way to handle storage. It automatically transitions data to lower-cost storage tiers, aligning with the company's budget constraints.
- E. Incorrect.
A hybrid architecture could increase complexity and costs without necessarily addressing the performance and scalability needs of the workload.
