A company uses an Amazon Elastic File System (Amazon EFS) file system to share files across many Linux Amazon EC2 instances. A SysOps administrator notices that the file system's PercentIOLimit metric is consistently at 100% for 15 minutes or longer. The SysOps administrator also notices that the application that reads and writes to that file system is performing poorly. They application requires high throughput and IOPS while accessing the file system.
What should the SysOps administrator do to remediate the consistently high PercentIOLimit metric?

• A.Modify the existing EFS file system and activate Max I/O performance mode.
• B.Create a new EFS file system that uses Max I/O performance mode. Use AWS DataSync to migrate data to the new EFS file system.
• C.Create an EFS lifecycle policy to transition future files to the Infrequent Access (IA) storage class to improve performance. Use AWS DataSync to migrate existing data to IA storage.
• D.Modify the existing EFS file system and activate Provisioned Throughput mode.

• A.Enable encryption on each host's connection to the Amazon EFS volume Each connection must be recreated for encryption to take effect
• B.Enable encryption on the existing EFS volume by using the AWS Command Line Interface
• C.Enable encryption on each host's local drive Restart each host to encrypt the drive
• D.Enable encryption on a newly created volume and copy all data from the original volume Reconnect each host to the new volume
