A SysOps Administrator must evaluate storage solutions to replace a company’s current user-shared drives infrastructure.Any solution must support security controls that enable Portable Operating System Interface (POSIX) permissions and Network File System protocols.Additionally, any solution must be accessible from multiple Amazon EC2 instances and on-premises servers connected to the Amazon VPC.
Which AWS service meets the user drive requirements?
Amazon S3
Amazon EFS
Amazon EBS
Amazon SQS
Explanations:
Amazon S3 is an object storage service and does not support POSIX permissions or NFS protocols, which are required by the scenario.
Amazon EFS is a scalable file storage service that supports POSIX permissions and NFS protocols, making it ideal for multiple EC2 instances and on-premises servers connected to the VPC.
Amazon EBS is block storage designed for individual EC2 instances and does not support shared access or NFS protocols.
Amazon SQS is a message queuing service and does not provide file storage, nor does it support POSIX permissions or NFS protocols.
