What is recommended to unmount an attached server and increase the volume size?

  1. Virtual Tape Library

  2. Amazon EC2 Instances

  3. EBS Volume

  4. Optimized EC2 Instance

The correct answer is: EBS Volume

The recommended approach to unmount an attached server and increase the volume size involves using EBS (Elastic Block Store) volumes. EBS volumes are highly available, scalable storage options designed specifically for use with Amazon EC2 instances. When you need to increase the storage capacity of your application running on an EC2 instance, you can modify the size of the EBS volume attached to that instance. To do this, you first unmount the EBS volume from the EC2 instance. This step ensures that all data writes are complete and that the data integrity is maintained. Once unmounted, you can resize the EBS volume through the AWS Management Console, CLI, or API. After resizing, you may need to mount the EBS volume back to the EC2 instance to access the additional storage space. Other options listed do not directly pertain to the act of unmounting and resizing storage volumes. For instance, a Virtual Tape Library acts as a cloud storage solution for backups, but it doesn't function for resizing volumes directly attached to servers. Amazon EC2 Instances themselves are computing resources and don't inherently manage volume resizing. Optimized EC2 Instances refer to configurations tailored for specific performance requirements but do not involve the storage volume resizing process. In summary,
