Difficulty: HardAWS Storage Services

A healthcare software provider is deploying a patient management platform on AWS. The platform has two specific storage requirements:

1. A shared file storage system that can be accessed concurrently by a fleet of Linux-based Amazon EC2 application servers distributed across multiple Availability Zones to share state and configuration files.
2. A cost-effective archiving repository for patient medical records that are rarely accessed but must be preserved for 7 years to meet compliance standards, with the ability to retrieve any record within a few minutes if requested.

Which two AWS storage options should the provider select to fulfill these requirements? (Select TWO.)

  1. Amazon Elastic File System (Amazon EFS) for the shared application state and configuration files.Answer
  2. Amazon S3 Glacier Flexible Retrieval for the long-term archiving of medical records.Answer
  3. C
    Amazon Elastic Block Store (Amazon EBS) with Multi-Attach enabled for the shared application state and configuration files.
  4. D
    Amazon EC2 Instance Store for the long-term archiving of medical records, relying on AWS physical replication for durability.
  5. E
    Amazon S3 Standard for the long-term archiving of patient medical records to ensure the lowest storage cost.

Answer

Amazon Elastic File System (Amazon EFS) and Amazon S3 Glacier Flexible Retrieval are the correct storage options.
The correct options are Amazon Elastic File System (Amazon EFS) and Amazon S3 Glacier Flexible Retrieval. EFS provides a fully managed shared file system that can be mounted concurrently by multiple EC2 instances across multiple Availability Zones. S3 Glacier Flexible Retrieval is designed for cost-effective, long-term archiving of rarely accessed data, with Expedited retrieval options that deliver files within 1-5 minutes.

Step-by-Step Solution

1
Analyze the first requirement: a shared file system accessible concurrently by multiple Linux EC2 instances across multiple Availability Zones.
Identify Amazon Elastic File System (Amazon EFS) as the managed solution designed for concurrent, multi-AZ shared file storage for Linux workloads.
Amazon EBS volumes are typically restricted to a single instance and a single AZ, and Instance Store is local ephemeral block storage.
2
Analyze the second requirement: long-term, cost-effective archiving of regulatory compliance documents (7 years retention) that are rarely accessed but need retrieval in minutes.
Identify Amazon S3 Glacier Flexible Retrieval as the appropriate storage tier because it provides low-cost archiving and supports Expedited retrievals in 1-5 minutes.
Amazon S3 Standard is too expensive for rarely accessed archiving, and EC2 Instance Store does not persist data, failing the 7-year durability requirement.

Key Concept

Selecting appropriate AWS storage services based on access pattern, latency, concurrency, durability, and cost requirements.
