Difficulty: EasyAWS Storage Services

A company needs to configure storage in AWS for two distinct use cases. First, they need a highly durable object storage solution to store and retrieve static office documents. Second, they need a persistent block storage volume to attach to a single Amazon EC2 instance for a relational database. Which two AWS storage services should the company use to meet these requirements? (Select TWO)

  1. Amazon Simple Storage Service (Amazon S3)Answer
  2. Amazon Elastic Block Store (Amazon EBS)Answer
  3. C
    Amazon Elastic File System (Amazon EFS)
  4. D
    Amazon S3 Glacier Flexible Retrieval
  5. E
    Amazon EC2 Instance Store

Answer

The company should use Amazon Simple Storage Service (Amazon S3) for document object storage, and Amazon Elastic Block Store (Amazon EBS) for database block storage.
Amazon Simple Storage Service (Amazon S3) is the correct choice for storing static documents because it is designed for highly durable object storage. Amazon Elastic Block Store (Amazon EBS) is the correct choice for the relational database because it provides persistent, low-latency block storage that can be attached to a single EC2 instance.

Step-by-Step Solution

1
Analyze the first requirement: highly durable object storage for static office documents.
Identify Amazon Simple Storage Service (Amazon S3) as the primary AWS service designed for object storage with high durability.
Amazon S3 is built to store and retrieve any amount of data as objects from anywhere on the web, making it the perfect fit for static files like documents.
2
Analyze the second requirement: persistent block storage attached to a single EC2 instance for a database.
Identify Amazon Elastic Block Store (Amazon EBS) as the primary AWS service that provides persistent, low-latency block-level storage volumes for EC2 instances.
Databases require high-performance, persistent block storage, which is the primary use case for Amazon EBS volumes.
