Oracle Cloud Infrastructure 2021 Architect Associate — Question 40

You deployed an Oracle Cloud Infrastructure (OCI) compute instance (VM.Standard2.16) to run a SQL database. After a few weeks, you need to increase disk performance by using NVMe disks but keeping the same number of CPUs. As a first step, you terminate the instance and preserve the boot volume.
What is the next step?

Answer options

• A. Create a new instance using a VM.DenseIO2.16 shape using the preserved boot volume and move the SQL Database data to block volume.
• B. Create a new instance using a VM.DenseI02.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
• C. Create a new instance using a VM.Standard1.16 shape using the preserved boot volume and move the SQL Database data to NVMe disks.
• D. Create a new instance using a VM.DenseIO2.8 shape using the preserved boot volume and move the SQL Database data to NVMe disks.

Correct answer: B

Explanation

The correct answer is B because creating a new instance with the VM.DenseIO2.16 shape allows for NVMe disk usage, which will enhance the disk performance required for the SQL database. Options A and D do not provide the right instance shape for NVMe disks, while option C uses the wrong shape and does not meet the performance requirements.
