AWS Certified SysOps Administrator – Associate — Question 403

A user working in the Amazon EC2 console increased the size of an Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 Windows instance. The change is not reflected in the file system.
What should a SysOps administrator do to resolve this issue?

Answer options

• A. Extend the file system with operating system-level tools to use the new storage capacity.
• B. Reattach the EBS volume to the EC2 instance.
• C. Reboot the EC2 instance that is attached to the EBS volume.
• D. Take a snapshot of the EBS volume. Replace the original volume with a volume that is created from the snapshot.

Correct answer: A

Explanation

After resizing an Amazon EBS volume, the extra capacity is present on the disk but is unallocated. To make use of this space, a SysOps administrator must use operating system tools (such as Disk Management in Windows) to extend the existing file system into the newly available space. Rebooting, reattaching, or restoring from a snapshot will not automatically expand the partition size.
