Which three options can you use to expand the size of block volumes?

The correct answer involves considering various methods to expand block volumes in Oracle Cloud Infrastructure (OCI).

Expanding an existing volume in-place with online resizing is a valid and straightforward method, allowing for an increase in capacity without downtime. This approach is beneficial for critical applications that require high availability since it ensures that operations can continue smoothly during the resizing process.

Cloning an existing volume also presents a means of expanding volume size. By creating a clone of the current volume while specifying a larger size, you can effectively create a new volume that meets your expanded storage needs. This method can be particularly useful when you require both the original and the new, larger volume to coexist for data migration purposes or backup processes.

Taking a backup and restoring it to a larger volume is another method of achieving expansion. By backing up the data from the current volume and then restoring it to a newly created larger volume, you can ensure that all existing data is preserved while also facilitating the desired increase in size.

Lastly, expanding an existing volume in-place with offline resizing, while valid, imposes downtime during the resizing process as it requires the volume to be detached first. This method is less desirable in environments where uptime is critical, but it remains a viable option for those scenarios.
