The correct answer is A. Change the instances to an instance family that supports instance store volumes for the E. Deploy an Amazon Elastic File System (Amazon EFS) Regional file system to store the long-term. Instance store volumes provide high-performance, ephemeral storage that is ideal for temporary files.

Question
A company deploys a new payroll application on a set of two Amazon EC2 instances that run Amazon Linux. The instances have one root volume that stores the operating system and the application. The application needs to store temporary files and provide long-term file storage for all payroll data. Both storage options must have high performance and be compatible with Linux. Both EC2 instances must be able to access long-term payroll data from a single location. The long-term payroll data must be highly available. Which combination of actions will meet these requirements? (Choose two.)
Options
- AChange the instances to an instance family that supports instance store volumes for the
- BDeploy an Amazon ElastiCache (Redis OSS) instance. Configure the EC2 instances to save the
- CCreate an Amazon S3 bucket. Configure the EC2 instances to save temporary data to the S3
- DCreate and attach a new Amazon Elastic Block Store (Amazon EBS) volume to each of the two
- EDeploy an Amazon Elastic File System (Amazon EFS) Regional file system to store the long-term

Explanation
Instance store volumes provide high-performance, ephemeral storage that is ideal for temporary files. They are directly attached to the host and compatible with Linux, making them a good fit for fast, non-persistent temporary data. Amazon EFS is a highly available, scalable, shared file system that multiple Linux EC2 instances can mount concurrently from a single location. This meets the requirement for long-term, shared, highly available payroll data storage accessible by both EC2 instances.
