AWS Certified Solutions Architect Associate SAA-C03 Practice Question
Your application will store large data files that are frequently accessed for the first 30 days, after which they are rarely accessed. Which storage option aligns most closely with these access patterns to balance performance and cost?
Use Amazon EBS Cold HDD (sc1) volumes for data storage, as they are designed for less frequently accessed workloads.
Use Amazon EFS with the Infrequent Access storage class for all the files since they will become infrequently accessed.
Store the data on Amazon Glacier, as it is the most cost-effective option for rarely accessed data.
Use Amazon S3 to store data, setting a lifecycle policy to transition to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
Amazon S3 offers the ability to configure a lifecycle policy that can transition objects to a lower-cost storage class after a set period of time. In this case, storing files in S3 Standard for immediate and frequent access, then automatically transitioning them to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days, provides a cost-effective solution that still maintains reasonable access to the data when needed. Other options do not provide the same level of cost optimization aligned with the described access pattern, either lacking lifecycle management or being optimized for different access patterns.
