C: Define VCN, Private Client subnet, and Private Backup subnet:
* These network components are necessary to ensure secure connectivity and backup configurations.
* TheVCN (Virtual Cloud Network)provides network isolation.
* ThePrivate Client subnetenables secure client connections.
* ThePrivate Backup subnetis required for secure access toOCI Object Storagefor backups.
E: Create Exadata Infrastructure and VM Cluster resource:
* Exadata Infrastructure represents the physical hardware.
* VM Cluster resource defines compute and storage resources for the databases.
* Both must be set up before provisioning the actual database instance.
Why the other options are incorrect:
* A. VCN and Universal Cloud Credits:Insufficient; more configuration is needed.
* B. Service Backup subnet:Incorrect, it should be aPrivate Backup subnet.
* D. No prerequisites:Incorrect; prerequisites include both network and infrastructure setup.
