Explanation:
Amazon EBS Elastic Volumes allow you to dynamically increase the size of existing EBS volumes with no downtime or performance impact. After you increase the volume size at the AWS level, you log onto the EC2 instance and use file system commands (like resize2fs or xfs_growfs) to extend the file system. This is the fastest method to remediate the errors.

A company has an Amazon EC2 instance that supports a production system. The EC2 instance is backed by an Amazon Elastic Block Store (Amazon EBS) volume. The EBS volume's drive has filled to 100% capacity, which is causing the application on the EC2 instance to experience errors. Which solution will remediate these errors in the LEAST amount of time?
A
Modify the EBS volume by adding additional drive space. Log on to the EC2 instance. Use the file system-specific commands to extend the file system.
B
Create a snapshot of the existing EBS volume. When the snapshot is complete, create an EBS volume of a larger size from the snapshot in the same Availability Zone as the EC2 instance. Attach the new EBS volume to the EC2 instance. Mount the file system.
C
Create a new EBS volume of a larger size in the same Availability Zone as the EC2 instance. Attach the EBS volume to the EC2 instance. Copy the data from the existing EBS volume to the new EBS volume.
D
Stop the EC2 instance. Change the EC2 instance to a larger instance size that includes additional drive space. Start the EC2 instance.
