OCI Dedicated Region provides a fully managed Oracle Cloud Infrastructure region in a customer's data center, allowing them to meet regulatory compliance while running cloud services on-premises.

=================

OCI Network Load Balancer provides traffic distribution with high throughput and very low latency. Oracle documents its operation at Layers 3 and 4, making option B the best answer among the available choices. Its listeners support transport-level traffic, including TCP and UDP, without requiring application-level HTTP routing decisions. This makes it suitable for workloads that need efficient connection handling and minimal processing overhead. Depending on its configuration, it can also preserve source IP information. Complex Layer 7 routing is associated with application-aware load balancing. Network Load Balancer supports both public and private deployments, so it is neither restricted to web protocols nor limited to database traffic within private subnets.

Compartment quotas are applied on a per-compartment basis in Oracle Cloud Infrastructure. Each compartment has its own set of quota limits for resources and services that are enforced within that compartment.

=================

OCI security responsibilities are divided between Oracle and the customer. Oracle protects the infrastructure used to deliver cloud services, including physical facilities, hardware, and underlying networking components. Customers remain responsible for how they use and configure those services, including access policies, application security, data handling, and network security settings. For customer-managed compute environments, responsibilities also include maintaining the operating system and application software. The precise division varies with the service and its level of management, but using OCI does not transfer every security obligation to Oracle. Third-party tools may assist customers without replacing this division of responsibility. Option C best summarizes the model while recognizing that both parties contribute to the overall security of deployed workloads. Oracle documentation: Shared Security Model
