1z0-1151-25 Practice Exam Questions with Answers Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Certification

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 simplifies management by allowing customers to use the Google Cloud console and GCP automation tools (e.g., Terraform) to provision and manage databases, integrating seamlessly with GCP workflows. It doesn’t shift tasks to OCI (Option B), nor does OCI embed a console in GCP (Option C). Option D contradicts the multicloud ease-of-use goal. This is a key feature highlighted in Oracle’s June 2024 Google Cloud partnership announcement.

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.

The physical architecture of Oracle Database@Azure consists of OCI pods deployed within Azure data centers, fully equipped with OCI infrastructure, Exadata Database Service, and all dependencies, acting as an extension of OCI. Option A incorrectly splits dependencies, Option C misrepresents the pod location, and Option D confuses OCI ADs with Azure zones. Oracle’s architecture docs confirm this co-located, self-contained design.

The Partner Service Key is provided by Microsoft when configuring the Azure ExpressRoute circuit, which is then used in OCI to link the FastConnect virtual circuit to the interconnect. It’s not sourced from OCI (Options A and D) or tied to a VPN (Option C). This key ensures secure pairing of the two clouds, as specified in Oracle’s OCI-Azure Interconnect setup guide.

Oracle Autonomous Database on Shared Exadata Infrastructure is optimized for data warehousing (Option A), mixed workloads (Option B), and transaction processing (Option D), leveraging Exadata’s performance and automation. High-performance computing (HPC, Option C), typically involving compute-intensive tasks like simulations, is not a primary focus—OCI offers separate HPC solutions. Oracle’s documentation confirms these workload optimizations.

In Oracle Database@Azure, the Azure portal is used for managing and maintaining Exadata VM clusters and infrastructure, aligning with its Azure-native management approach. Data Guard (Option A), database homes (Option B), and container/pluggable databases (Option D) are configured post-provisioning, often via database tools, not directly as portal tasks. Oracle’s documentation specifies this infrastructure focus in Azure.

Configuring the Oracle Interconnect for Google Cloud requires Virtual Circuits on OCI (via FastConnect) and Partner Interconnects on GCP, establishing a private, high-speed link between the clouds. A direct internet connection (Option A) defeats the purpose of a private interconnect, while Microsoft Active Directory (Option B) is unrelated to network setup. Public subnets (Option D) are not required—private connectivity is the goal. This setup is detailed in Oracle’s multicloud networking documentation.

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.

The first step in onboarding Oracle Database@Azure is consulting Oracle Sales to negotiate a price agreement, resulting in a Private Offer in the Azure Marketplace. This purchase is a prerequisite before technical onboarding steps like linking accounts (Option A, optional) or using an Azure subscription (Option B, a requirement but not the first action) can proceed. Option D misplaces the sequence, as the private offer purchase initiates onboarding. Oracle’s official onboarding guide specifies this sales-driven process.
