1. You want to move an Exadata Cloud@Customer VM cluster to a different OCI compartment for increased isolation from other teams that use Exadata. What happens when you use the console to do this?

A) After it is deployed, a VM cluster cannot change compartments.
B) The VM cluster and associated databases will move to the new compartment. All other resources will remain in the existing compartment.
C) The vm cluster, compute nodes, and associated databases will move compartments. All other resources will remain in the existing compartment.
D) The vM cluster, compute nodes, and underlying Exadata infrastructure will move to the new compartment. All other resources remain the same.

2. Resources are allocated to the DB system based on the shape selected. Which TWO are options for a DB system? (Choose all correct answers)

A) One-node virtual machine XS with 24 OCPU cores
B) Two-node bare metal servers with 512 GB memory and locally attached drives
C) One-node bare metal server with up to 52 OCPU cores and locally attached drives to the system
D) Two-node virtual machine X7 with Block Storage which can be scaled up

3. Which statement is true about moving virtual machine (VM) database (DB) systems from one compartment to another?

A) You do not need access permissions to the compartment that the resource Is being moved to when moving VM DB systems to a different compartment.
B) You have to move dependent resources like Database Homes and databases to the destination compartment before moving the VM DB system.
C) You can move DB systems to a different compartment if you have sufficient access permissions to the compartment that the resource is being moved to, as well as the current compartment.
D) You can move VM DB systems from one compartment to another by only using Oracle Cloud Infrastructure REST APIs.

4. Which two statements are true about changing the shape of a virtual machine (VM) database (DB) system to adapt to changes in performance needs?
(Choose all correct answers)

A) After you provision a VM DB system with a shape that supports Oracle RAC, you can change that shape to another shape that does not support Oracle RAC.
B) If the current shape of the VM DB system supports Oracle Real Application Clusters (RAC), then you can only change that shape to another shape that also supports Oracle RAC.
C) It is possible to change the shape of a VM DB system with a higher number of OCPUs. However, reducing the number of OCPUs is not permitted.
D) After you provision a VM DB system, you cannot change the shape. You have to provision another VM DB system using a full backup.
E) The shape of a VM DB system can be changed at any time, with no impact on the amount of storage available to the DB system.
