A startup is deploying a web application on AWS. They need a storage option to act as a persistent boot volume for their Amazon EC2 instances, and another storage option to serve as a shared file storage that multiple EC2 instances can mount and access simultaneously.
Which two AWS storage services should the startup select?
- Amazon Elastic Block Store (Amazon EBS)Answer
- Amazon Elastic File System (Amazon EFS)Answer
- CAmazon Simple Storage Service (Amazon S3)
- DAmazon EC2 Instance Store
- EAmazon S3 Glacier
Answer
Amazon Elastic Block Store (Amazon EBS) and Amazon Elastic File System (Amazon EFS)
Amazon Elastic Block Store (Amazon EBS) is the correct choice for the persistent boot volume because it provides durable, block-level storage volumes that persist independently of the EC2 instance lifetime. Amazon Elastic File System (Amazon EFS) is the correct choice for shared file storage because it provides a serverless file system that can be mounted by multiple EC2 instances at the same time using the NFS protocol.
