The Oracle Base Database Service in OCI leverages Availability Domains (ADs) and Fault Domains (FDs) to ensure high availability (HA) and disaster recovery (DR). ADs are isolated data centers within a region, preventing single points of failure, while FDs are subdivisions within an AD, further isolating hardware for redundancy. Availability Sets and Zones (Options A and B) are Azure-specific terms, and Geography (Option C) is too vague. OCI’s architecture documentation confirms ADs and FDs as the foundation for HA/DR in database services.

Oracle Database@Google Cloud offers Public and Private purchase options via the Google Cloud Marketplace. Public offers are standardized and directly available, while Private offers involve negotiated terms with Oracle Sales. Options A and C are not official terms, and Free Tier (Option D) doesn’t apply to this enterprise service. Oracle’s purchasing documentation defines these two types.

In Oracle Database@Google Cloud, Google Cloud Virtual Private Cloud (VPC) is used to create an isolated network environment within GCP, securing Oracle database services from other resources. This isolation enhances security by restricting access to the databases and ensuring they operate within a private subnet. Option B contradicts the private nature of the service, while Options C and D are unrelated to VPC’s role. Oracle’s documentation on Database@Google Cloud emphasizes VPC for network segmentation and security.

An existing Azure subscription is the foundational prerequisite for subscribing to Oracle Database@Azure, as the service is provisioned and billed through Azure. While a private interconnect (Option A) and linked OCI account (Option C) enhance functionality, they are not mandatory to initiate subscription—linking occurs post-subscription. A custom identity domain (Option D) is optional for federation but not a prerequisite. Oracle’s subscription process documentation confirms this requirement.

Oracle Database@Google Cloud connects to OCI via a dedicated, redundant dark fiber network managed by Oracle, ensuring low-latency and high-reliability communication. VPN (Option A) and public internet (Option C) are less performant, and GCP’s internal network (Option D) isn’t the primary link—Oracle manages the interconnect. This is detailed in Oracle’s multicloud architecture docs.

Oracle Database@Google Cloud is a multicloud service that integrates OCI database offerings into the Google Cloud Platform (GCP). According to official Oracle documentation, the Autonomous Database on Dedicated Infrastructure is a key service available in this offering. This service provides a fully managed database environment running on dedicated Exadata infrastructure, optimized for performance and isolation. The Base Database Service is a more basic offering not specifically highlighted in the Oracle Database@Google Cloud context, while HeatWave (listed twice in the original, corrected here as a single option) is a MySQL-focused analytics engine, not the primary native database service for this integration. The partnership between Oracle and Google Cloud, announced in June 2024, emphasizes Autonomous Database capabilities for enterprise workloads.

Configuring Oracle Interconnect for Google Cloud requires creating a Partner Interconnect VLAN attachment in GCP, which pairs with OCI’s FastConnect virtual circuit for private connectivity. Shared VPC (Option A) is unrelated, NAT gateways (Option C) are for internet access, and “Cross-Cloud Interconnect” (Option D) is not a GCP term. Oracle’s setup guide confirms the VLAN attachment’s role.

With Oracle Database@Google Cloud, customers are responsible for provisioning Exadata Infrastructure via the Google Cloud Console, aligning with the service’s design to manage resources within GCP. Updating infrastructure/software (Option B) and provisioning VM clusters in OCI (Option D) are managed by Oracle, not the customer. Provisioning containers/pluggable databases (Option C) occurs post-infrastructure setup, not as the primary responsibility. Oracle’s documentation emphasizes customer control over provisioning in GCP.

The Oracle Interconnect for Google Cloud is available only in specific regions where Oracle and Google have established cross-cloud interconnect partnerships, such as Ashburn, London, and Frankfurt (as of June 2024 announcements). It’s not globally available across all OCI and GCP regions (Option A), nor restricted to North America (Option C) or FastConnect-only regions (Option D). The partnership leverages OCI FastConnect and GCP Partner Interconnect in these designated locations, as outlined in Oracle’s multicloud connectivity documentation.

Oracle Database@Azure allows provisioning of Exadata Infrastructure through the Azure portal and APIs, integrating seamlessly with Azure’s management ecosystem. The OCI console (Option A) and OCI Terraform scripts (Option B) are not used for this Azure-native service. Azure Terraform scripts (Option C) are possible but not the primary interface highlighted in Oracle’s documentation, which emphasizes the Azure portal/APIs.

The onboarding process for Oracle Database@Google Cloud primarily involves purchasing the service (via Google Cloud Marketplace) and configuring the resources (e.g., Exadata Infrastructure in GCP). Options B, C, and D include preparatory or optional steps, but the core onboarding focuses on purchase and initial setup, as per Oracle’s documentation. This streamlined process reflects the service’s integration into GCP workflows.
