1Z0-1067-25 practice question 15 of 15

The boot volume on your Oracle Linux instance has run out of space. Your application has crashed due to a lack of swap space, forcing you to increase the size of the boot volume. Which step should NOT be included in the process used to solve the issue? (Choose the best)

Full set: 93 questions
Answer options
A:

A. Resize the boot volume by specifying a larger value than the boot volume current size.

B:

B. Reattach the boot volume and restart the instance.

C:

C. Create a RAID 0 configuration to extend the boot volume file system onto another block volume.

Correct answer
D:

D. Attach the resized boot volume to a second instance as a data volume; extend the partition and grow the file system in the resized boot volume.

E:

E. Stop the instance and detach the boot volume.

Correct Answer:
C. C. Create a RAID 0 configuration to extend the boot volume file system onto another block volume.
Explanation

The process of resizing a boot volume involves increasing its size at the infrastructure level and then extending the partition and file system at the OS level to utilize the new space. Creating a RAID 0 configuration is a completely different method for increasing storage capacity. It involves striping data across multiple volumes to create a single larger logical volume. This is not a step in the procedure for resizing an existing single boot volume and would be an alternative, more complex solution to the storage problem, not part of the direct resize process.

Why Incorrect

A. Resizing the boot volume to a larger value in the OCI console or via the API is the fundamental first step.
B. Reattaching the boot volume to the original instance and restarting it is the final step to bring the application back online.
D. Attaching the volume to a second instance is a valid and safe method to perform the OS-level partition and file system extension.
E. Stopping the instance is a mandatory prerequisite for resizing an attached boot volume to ensure data consistency.

The steps include stopping the instance, editing the volume size, and then extending the partition within the OS. It does not mention creating a RAID configuration as part of this process.
