Difficulty: EasyAWS Storage Services

An educational institution is deploying a web portal on AWS. The portal requires a shared storage directory where multiple web servers (EC2 instances) can read and write media files at the same time. Additionally, the portal needs a dedicated, persistent storage volume attached to a single database server (EC2 instance) to store transaction logs.

Which TWO AWS storage services should the institution choose to satisfy these requirements? (Select TWO.)

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

Answer

Amazon Elastic File System (Amazon EFS) and Amazon Elastic Block Store (Amazon EBS)
Amazon Elastic File System (Amazon EFS) is a fully managed file storage service that supports the Network File System (NFS) protocol, allowing multiple EC2 instances to access the storage concurrently. Amazon Elastic Block Store (Amazon EBS) provides high-performance, persistent block storage volumes designed for a single EC2 instance, making it suitable for running databases and storing transaction logs.

Step-by-Step Solution

1
Identify the storage requirements for the shared media directory.
The requirements specify a shared storage directory that multiple EC2 instances can read and write to simultaneously.
This points to a shared file storage solution, which is addressed by Amazon Elastic File System (Amazon EFS).
2
Identify the storage requirements for the database server.
The requirements specify a dedicated, persistent storage volume for a single EC2 instance to store transaction logs.
This points to a persistent block storage solution, which is addressed by Amazon Elastic Block Store (Amazon EBS).

Key Concept

Selecting appropriate AWS storage services based on file-sharing and persistence needs.
