Which action should a SysOps administrator take to improve the performance of the file system?

A company is using Amazon Elastic File System (Amazon EFS) to share a file system among several Amazon EC2 instances. As usage increases, users report that file retrieval from the EFS file system is slower than normal.

Which action should a SysOps administrator take to improve the performance of the file system?
A . Configure the file system for Provisioned Throughput.
B . Enable encryption in transit on the file system.
C . Identify any unused files in the file system, and remove the unused files.
D . Resize the Amazon Elastic Block Store (Amazon EBS) volume of each of the EC2 instances.

Answer: A

Explanation:

Step-by-Step

Understand the Problem:

Users report that file retrieval from the Amazon EFS file system is slower than normal.

Analyze the Requirements:

Improve the performance of the EFS file system to handle increased usage and file retrieval speed.

Evaluate the Options:

Option A: Configure the file system for Provisioned Throughput.

Provisioned Throughput mode allows you to specify the throughput of your file system independent of the amount of data stored.

This option is suitable for applications with high throughput-to-storage ratio requirements and ensures consistent performance.

Option B: Enable encryption in transit on the file system.

While this enhances security, it does not directly improve performance.

Option C: Identify any unused files in the file system, and remove the unused files.

This may free up some resources but does not address the root cause of slow performance.

Option D: Resize the Amazon EBS volume of each of the EC2 instances.

EFS performance issues are not directly related to the size of EBS volumes attached to EC2 instances.

Select the Best Solution:

Option A: Configuring the file system for Provisioned Throughput ensures consistent performance by allowing you to set the required throughput regardless of the amount of data stored.

Provisioned Throughput Mode

Configuring Provisioned Throughput for Amazon EFS provides a consistent and higher performance level, which is suitable for high throughput requirements.
