Actual exam question from Oracle's 1z0-932

Question #: 113
Topic #: 1

You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your application down enough to impair user access. The application is currently using a VM.Standard1.2 compute without any block storage attached to it.
Which two options allow you to increase disk performance? (Choose two.)

A. Terminate the compute instance preserving the 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 a VM Dense IO shape and restore the backup.

A & C are correct. - B is incorrect as it states that preserve the boot volume but didn't mention to use preserved boot volume to launch the new instance. - D is incorrect as it states that terminate instance and create the backup, so when instance is terminated will lose the boot volume where is in A option it mention to terminate instance by preserving the boot volume.

we can't create new instance shape based on preserved boot volume, we can only increase the size or performance while restoring

we can create new instance shape based on preserved boot volume. Refer: https://docs.cloud.oracle.com/en-us/iaas/Content/Block/Concepts/bootvolumes.htm

A and C os the right answer. You need to connect the boot volume you preserved to the new instance.

No you dont need to terminate. You can make a backup of a boot volume while it is attached to a running instance, or you can make a backup of a boot volume while it is detached from the instance. https://docs.cloud.oracle.com/en-us/iaas/Content/Block/Concepts/bootvolumebackups.htm Answer is A and C.

if you don't need to terminate why A is correct. If u have to switch the instance, it's better to terminate it.

If you terminate by default it delete the boot volume
