Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company is testing an application that runs on an Amazon EC2 Linux instance. The instance contains a data volume of 500 GB that consists of a single Amazon
Elastic Block Store (Amazon EBS) General Purpose SSD (gp2) volume.
The application is now ready for production use and will be installed on multiple EC2 instances that run in an Auto Scaling group. All instances need access to the data that was stored on the 500 GB volume. The company needs a highly available and fault-tolerant solution that does not introduce any significant changes to the application's code.
Which solution meets these requirements?

  • A. Provision an EC2 instance with NFS server software that is configured with a single 500 GB gp2 volume.
  • B. Use an Amazon FSx for Windows File Server file system that is configured as an SMB file store within a single Availability Zone.
  • C. Migrate the data into an Amazon S3 bucket. Use an EC2 instance profile to access the contents of the bucket.
  • D. Use an Amazon Elastic File System (Amazon EFS) file system that is configured with the General Purpose performance mode.

Selected Answer: D
EBS volumes that are attached to an instance are exposed as storage volumes that persist independently from the life of the instance. You can create a file system on top of these volumes, or use them in any way you would use a block device (such as a hard drive). You can dynamically change the configuration of a volume attached to an instance. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AmazonEBS.html
