1z0-1151-25 Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Questions and Answers

Oracle Database@Azure allows customers to provision and manage Oracle database resources directly within the Azure portal, streamlining multicloud operations. Specifically, the Oracle Exadata Infrastructure and Exadata VM Cluster are provisioned through Azure, integrating OCI database capabilities into the Azure ecosystem. Options involving the OCI console (B and C) are incorrect because this service is designed for Azure-native management. Option D overextends by including container and pluggable databases, which are managed post-provisioning, not part of the initial infrastructure setup in Azure. This is detailed in the Oracle Database@Azure service documentation.

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.

HeatWave in OCI’s MySQL Database Service is a distributed in-memory query accelerator, enhancing analytical query performance for MySQL workloads. It’s not primarily for migration (Option B), HA (Option C), or serverless deployment (Option D), though it integrates with HA features. Oracle’s HeatWave documentation highlights its in-memory acceleration focus.

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 OCI-Azure Interconnect supports direct traffic between Azure VNets and OCI VCNs (Option D) and peered VCNs in the same (Option B) or different OCI regions (Option A) via private IPs. However, it does not support transitive routing, such as traffic from an on-premises network through Azure to OCI (Option C), as the interconnect is a direct cloud-to-cloud link. This limitation is detailed in Oracle’s networking documentation for the OCI-Azure partnership.

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.

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.

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.

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.

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.

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 a 2-node Real Application Clusters (RAC) DB System in OCI, Fault Domains (FDs) within a single Availability Domain (AD) are used to distribute nodes, ensuring fault isolation at the hardware level (e.g., separate racks/power). Availability Domains (Option A) provide broader isolation but are overkill for a 2-node setup within one region. Local/Remote regions (Options B and D) are geographic, not instance-specific. Oracle’s HA documentation recommends FDs for RAC.

The In-Memory Database feature, which accelerates analytics and mixed workloads, is supported across all Oracle Database editions in OCI (e.g., Standard, Enterprise). RAC (Option A), Data Guard (Option C), and Advanced Security (Option D) are edition-specific or require additional licensing/configurations. Oracle’s database feature matrix confirms In-Memory’s universal availability in OCI deployments.
