A Company Uses an Amazon Elastic File System (Amazon EFS)

question 27

Multiple Choice

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) 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.
• B) 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.
• C) Modify the existing EFS file system and activate Max I/O performance mode.
• D) Modify the existing EFS file system and activate Provisioned Throughput mode.

Definitions:

Atrioventricular Node

A part of the electrical conduction system of the heart that helps regulate the heart rate by transferring signals from the atria to the ventricles.

Atrioventricular Bundle

A group of heart muscle fibers responsible for conducting impulses from the atria to the ventricles, ensuring coordinated heart contractions.

Pulse Pressure

The difference between systolic and diastolic blood pressure readings, indicating the force that the heart generates each time it contracts.

Left Atrium

The upper left chamber of the heart that receives oxygenated blood from the lungs and pumps it into the left ventricle.
