Oracle Cloud Infrastructure 2021 Multicloud Architect Associate — Question 51

Which statement about Oracle Cloud Infrastructure paravirtualized block volume attachments is TRUE? (Choose the best answer.)

Answer options

• A. Paravirtualized volumes may reduce the maximum IOPS performance for larger block volumes.
• B. Paravirtualized is required to manage iSCSI configuration for virtual machine instances.
• C. Paravirtualized volumes become immediately available on bare metal compute instances.
• D. Paravirtualization utilizes the internal storage stack of compute instance OS and network hardware virtualization to access block volumes.

Correct answer: A

Explanation

The correct answer, A, is true because paravirtualized volumes can indeed limit maximum IOPS performance as the size of the block volume increases. Option B is incorrect as paravirtualization is not specifically required for iSCSI management. Option C is false since paravirtualized volumes are not immediately available on bare metal compute instances. Option D is misleading as it describes virtualization but does not specifically address the performance implications related to IOPS.
