You are building an automated transcription service where Amazon EC2 worker instances process an uploaded audio file and generate a text file. You must store both of these files in the same durable storage until the text file is retrieved. Customers fetch the text files frequently. You do not know about the storage capacity requirements. Which storage option would be both cost-efficient and highly available in this situation?

Answer options:

A.Multiple Amazon EBS Volume with snapshots
B.A single Amazon Glacier Vault
C.A single Amazon S3 bucket
D.Multiple instance stores

Correct Answer – C
Amazon S3 is the perfect storage solution for audio and text files. It is a highly available and durable storage device.
Option A is incorrect because storing files in EBS is not cost-efficient.
Option B is incorrect because files need to be retrieved frequently so Glacier is not suitable.
Option D is incorrect because instance store is not highly available compared with S3.
