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.)
- Amazon Elastic File System (Amazon EFS)Answer
- Amazon Elastic Block Store (Amazon EBS)Answer
- CAmazon Simple Storage Service (Amazon S3)
- DAmazon EC2 Instance Store
- EAmazon 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.
