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

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.

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.

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.

Oracle Interconnect for Google Cloud is designed for multicloud scenarios between OCI and GCP, such as integrating Autonomous Database with GCP AI (Option A), disaster recovery (Option C), or latency-sensitive apps (Option D). Migrating on-premises data to OCI (Option B) is a single-cloud use case that doesn’t inherently require GCP connectivity, making it the least likely to need this interconnect. Oracle’s multicloud use case documentation supports this distinction.

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.

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.

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 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@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.

Oracle Database@Google Cloud enables customers to run OCI-native database services (e.g., Autonomous Database) within Google Cloud data centers, simplifying multicloud management via GCP tools. Option A overcomplicates the integrated setup, Option C contradicts the private interconnect, and Option D is false—Autonomous Database is included. Oracle’s June 2024 partnership announcement confirms this design.

The OCI-Azure Interconnect is the official Oracle-Microsoft partnership solution for establishing a private, high-bandwidth, and low-latency connection between OCI and Azure. This interconnect leverages Azure ExpressRoute and Oracle FastConnect to create a dedicated network link, bypassing the public internet for enhanced security and performance. A VPN connection (Option A) is possible but less optimal due to higher latency and lower reliability compared to the interconnect. Using the public internet (Option B) is insecure and unsuitable for mission-critical applications. This solution is detailed in Oracle’s multicloud architecture guides and the OCI-Azure partnership documentation, emphasizing its suitability for enterprise multicloud deployments.

A hub-and-spoke topology with a network virtual appliance (NVA) in GCP allows multiple application VPCs (spokes) to securely connect to a centralized Exadata Database Service (hub) without direct peering between VPCs. The NVA manages traffic and security. Direct Connect (Option B) isn’t a GCP term here, mesh peering (Option C) requires inter-VPC connections, and flat topology (Option D) is insecure. Oracle’s networking guide supports this topology for Database@Google Cloud.

Upgrading the existing Oracle Interconnect for Google Cloud bandwidth during surges and downgrading afterward meets the need for scalability and minimal disruption. This leverages the existing FastConnect and Partner Interconnect setup, avoiding new configurations like additional virtual circuits with ECMP (Option A), which adds complexity. VPN (Option C) and public internet (Option D) lack the performance and reliability of the interconnect. Oracle’s documentation supports dynamic bandwidth adjustments for such scenarios.
