Oracle Oracle Cloud Infrastructure 2025 Multicloud Architect Professional 1z0-1151-25 Exam Dumps: Updated Questions & Answers (May 2025)

The OCI-Azure Interconnect, using Azure ExpressRoute and Oracle FastConnect, provides a dedicated, private, high-bandwidth, and low-latency connection between Azure and OCI, ideal forsecure and efficient data transfer between frontend apps and backend data warehouses. Public internet (Option A) is less secure and slower, even with encryption. A hybrid approach (Option C) involves on-premises, not specified here. A VPN (Option D) is secure but lacks the performance of the interconnect. Oracle’s multicloud connectivity docs endorse this solution.

Oracle Interconnect for Google Cloud is a dedicated, private network connection between Oracle Cloud Infrastructure (OCI) and Google Cloud Platform (GCP), designed to provide secure, low-latency, and high-bandwidth connectivity. It leverages OCI FastConnect and GCP Partner Interconnect to enable seamless multicloud workloads, such as running OCI databases with GCP AI tools. Option A is incorrect as it pertains to Azure, not GCP. Option B focuses on on-premises migration, which is unrelated to this interconnect. Option D contradicts the cloud-based purpose. Oracle’s documentation highlights this as a key multicloud enabler announced in June 2024.

A primary benefit of Oracle Autonomous Database on Shared Exadata Infrastructure is its ability to automatically tune and patch the database, reducing manual administration and improving performance and security. Option B is unrelated to the shared infrastructure model, Option C exaggerates storage (it’s scalable, not unlimited), and Option D is a general infrastructure feature, not specific to Autonomous Database. Oracle’s documentation highlights automation as a core advantage.

In Oracle Database@Azure, Oracle Exadata Infrastructure and Exadata VM Clusters are provisioned via the Azure portal, integrating OCI database services into Azure’s ecosystem. Option B overextends to include container/pluggable databases (managed separately), while Options C and D incorrectly involve the OCI console—provisioning is Azure-native. Oracle’s documentation corrects the original answer (C) to A.

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.

Border Gateway Protocol (BGP) is a dynamic routing protocol used in the OCI-Azure Interconnect to automatically determine the optimal path for data between an Azure Virtual Network (VNet) and an OCI Virtual Cloud Network (VCN). Unlike static routing (Option A), BGP adapts to network changes, ensuring efficient and reliable connectivity. It doesn’t establish the connection itself(Option B) or manage security rules (Option C)—those are handled by FastConnect/ExpressRoute and security lists, respectively. Oracle’s networking documentation for multicloud interconnects confirms BGP’s role in route optimization.

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.

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.

FastConnect with an Oracle partner uses a third-party network to connect to OCI, while colocation with Oracle involves a direct physical connection at an OCI data center. The difference lies in the physical connection method, not locations (Option A), redundancy (Option B), or circuits (Option C). Oracle’s FastConnect documentation outlines these deployment models.

To accept a private offer in the Azure Marketplace for Oracle Database@Azure, the user must have the Billing Account Owner or Contributor role under the Microsoft Customer Agreement. This role grants permissions to manage billing and purchasing activities, which are required to finalize the private offer created by Oracle Sales. Options A and B lack the necessary billing authority, while Option D (Enterprise Administrator) is a broader role not specifically tied to Azure Marketplace transactions. This is outlined in Oracle’s Database@Azure onboarding process documentation.
