You need to be aware of Glacier's characteristics, purposes, and available alternatives for retrieval times and costs.
Make sure you know the operating systems you can use with the Amazon Elastic File System (EFS) before purchasing it (just Linux).
Make sure you are familiar with the several tiers of the Amazon Elastic Block Store (EBS), including instance stores. For instance, what would you select for a data store with excellent IO requirements and data dispersed over multiple instances? (Good use case for an instance store)
Discover Amazon FSx. You must be familiar with Lustre and FSx for Windows.
Check out this whitepaper to learn how to optimize Amazon S3 speed, including leveraging CloudFront and byte-range fetches.
Ensure you are familiar with the versioning and MFA remove object deletion protection options available for Amazon S3.

3 Steps to Get Certified

Compute

It would be best if you were well-versed in the possibilities for scaling an Auto Scaling Group using metrics like SQS queue depth or SNS message counts.
Learn about your target tracking policies as well as other auto-scaling policies.
Learn more about AWS's High-Performance Computing (HPC). You must be familiar with Amazon FSx with HPC use cases.
Understand the placement groupings. Verify your ability to distinguish between spread, cluster, and partition; for instance, what would you utilize for the lowest latency? What happens if you have to support a tightly linked app? Within an AZ or outside of one?
Ascertain that you are familiar with the distinctions between elastic network adapters (ENAs), elastic network interfaces (ENIs), and elastic fabric adapters (EFAs).
Ensure you comprehend how to assign IAM policies to the Amazon Elastic Container Service (ECS) to grant S3 access. How can Kinesis Firehose or SQS be separated from an ECS data processing process?
Ensure you understand the various Reserved Instances (RI) pricing models and the different RI choices, such as scheduled RIs.
Make sure you are aware of AWS Lambda's 15-minute or 900-second maximum execution time.
