Final answer:
In the shared security model of OCI, the customer is responsible for their customer data and the management of local NVMe data persistence whereas Oracle handles physical security and hypervisor security.
Step-by-step explanation:
According to the shared security model in Oracle Cloud Infrastructure (OCI), the customer's responsibilities include ensuring the security of their customer data and managing local NVMe data persistence.
Maintaining the physical security of OCI data center facilities and the security of the virtual machine hypervisor are responsibilities handled by Oracle as the cloud service provider. Object Storage data durability is also typically a provider's responsibility, where they ensure redundancy and integrity of the stored data.
