You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your applicationdown enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it.
Which two options allow you to increase disk performance? (Choose two.)

• A.Terminate the compute instance preservingthe boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
• B.Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.
• C.Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
• D.Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using aVM Dense IO shape and restore the backup.
