AWS Certified SysOps Administrator - Associate SOA-C02 — Topic 1 Question 11

Question

A SysOps administrator is provisioning an Amazon Elastic File System (Amazon EFS) file system to provide shared storage across multiple Amazon EC2 instances. The instances all exist in the same VPC across multiple Availability Zones. There are two instances in each Availability Zone. The SysOps administrator must make the file system accessible to each instance with the lowest possible latency. Which solution will meet these requirements?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create a mount target in each Availability Zone of the VPC. Use the mount target to mount the EFS file system on the instances in the respective Availability Zone. Amazon EFS is a shared, elastic NFS file system that multiple instances can mount concurrently across AZs. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
