Question

Difficulty: MediumAWS Storage Services

A media production company wants to implement a storage solution on AWS for two specific use cases. First, they need to store raw video footage that must be accessed and modified concurrently by multiple Amazon EC2 instances for collaborative editing. Second, they need to store final rendered video exports that are rarely accessed but must be available immediately for users to download. Which two AWS storage services or tiers should the company select to meet these requirements? (Select TWO).

  1. Amazon Elastic File System (Amazon EFS)Answer
  2. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)Answer
  3. C
    Amazon Elastic Block Store (Amazon EBS)
  4. D
    Amazon EC2 Instance Store
  5. E
    Amazon S3 Glacier Flexible Retrieval

Answer

Amazon Elastic File System (Amazon EFS) and Amazon S3 Standard-Infrequent Access (S3 Standard-IA)
The scenario requires shared file access for raw footage, which is best served by Amazon Elastic File System (Amazon EFS) because it allows multiple instances to read and write to the same storage system simultaneously. For the final exports that are infrequently accessed but require immediate retrieval, Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is the correct tier because it matches the access pattern while providing lower cost than S3 Standard and millisecond access times.

Step-by-Step Solution

1
Analyze the first requirement: concurrent, shared file-level storage for multiple EC2 instances.
Identify Amazon Elastic File System (Amazon EFS) as the service that supports shared file access across multiple instances simultaneously using the NFS protocol.
Block storage options like EBS do not support this standard multi-instance shared write capability natively.
2
Analyze the second requirement: low-cost storage for infrequently accessed objects that must be available immediately for download.
Identify Amazon S3 Standard-Infrequent Access (S3 Standard-IA) as the tier that provides low-cost storage with millisecond access times.
S3 Glacier tiers are lower cost but require minutes to hours for retrieval, which does not meet the immediate access requirement.

Key Concept

Selecting appropriate AWS storage services based on access pattern, durability, and sharing requirements.
