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