Question

A company has an NFS server that runs on a single Amazon EC2 instance. A SysOps administrator needs to replace the NFS server with a highly available file system. A total of 30 EC2 instances must connect to the file system to store and retrieve shared images and data. The EC2 instances are spread across multiple Availability Zones. The SysOps administrator will use Amazon Elastic File System (Amazon EFS) for the file system. Which solution will meet these requirements?

Options

  • ACreate a new EFS file system in each Availability Zone. Configure the file systems to use the EFS
  • BCreate a new EFS file system that uses the EFS Standard storage class. Configure each EC2
  • CCreate a new EFS file system in each Availability Zone. Configure the file systems to use the EFS
  • DCreate a new EFS file system that uses the EFS Standard storage class. Configure each EC2

Explanation

Amazon Elastic File System (EFS) is a highly available, scalable, and fully managed file system designed for workloads that require shared access across multiple EC2 instances and Availability EFS Standard storage class is required for multi-AZ high availability and redundancy. Each Availability Zone must have a mount target, and EC2 instances should connect to the mount target in their respective Availability Zones to minimize latency and optimize performance. EFS automatically scales to accommodate growing storage needs, making it a suitable replacement for the NFS server.
