Which two tasks must you perform?

A.
Point to a mount point that has existing files and directories.

B.
Connect to the DBaaS instance to which you attached the storage volume by using ssh or PuTTY as the opc user.

C.
Create a mount point on your instance.

D.
Connect to the DBaaS instance to which you attached the storage volume by using ssh or PuTTY as the oracle user.

Explanation:
To add temporary storage to a database deployment:
1. Use the Create Storage Volume wizard in the Compute Cloud Service console to create a storage volume.
2. Attach the storage volume to the Compute Cloud Service instance on which the compute node is running. When you attach the storage volume, it is assigned a
disk number. Note down this disk number for later use.
3. Connect as the opc user to the compute node.
4. Start a root-user command shell
$ sudo -s #
5. Confirm the addition of the storage volume by using the ls command:
# ls /dev/xvd*
6. Create a single, primary partition that occupies the entire storage volume by using the fdisk command.
7. Create a file system on the partition by using the mkfs command.
8. Create a directory to use as the mount point for the partition by using the mkdir command.
9. Mount the partition on the directory you just created by using the mount command.
10. Set the ownership and permissions of the mount-point directory appropriately by using the chown and chmod commands.
11. Exit the root-user command shell.
