1z0-1151-25 Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Free Practice Exam Questions (2025 Updated)

In Oracle Database@Azure, the Azure portal is used to scale up Exadata infrastructure (e.g., adding compute) and run software updates, aligning with its infrastructure management role. Database-specific tasks like scaling resources or backups (Option A) and DR configurations (Option D) occur at the database level, often via OCI tools. Option B incorrectly ties OCI services to Azure monitoring. Oracle’s management guide specifies these Azure portal functions.

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.

“Multicloud” refers to using services from multiple cloud providers (e.g., OCI, Azure, GCP) to leverage their unique strengths, enhancing flexibility, resilience, and cost-efficiency. Option A describes hybrid cloud, Option C is single-provider redundancy, and Option D is multi-region deployment—not multicloud. Oracle’s multicloud strategy documentation defines this approach as a key IT management enabler.

OCI Site-to-Site VPN connections use Internet Protocol Security (IPsec) to secure data transmission, providing encryption and authentication over the tunnel. SSL (Option A) and TLS (Option C) are typically used for web traffic, not VPNs, while DTLS (Option B) is designed for datagram-based applications, not standard VPNs. Oracle’s VPN documentation specifies IPsec as the protocol, aligning with industry standards for secure VPNs. The original question incorrectly listed SSL as the answer; IPsec is correct per OCI standards.

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.

A Site-to-Site VPN in OCI requires a Dynamic Routing Gateway (DRG) in the VCN, Customer Premises Equipment (CPE) at the on-premises site, and an IPsec tunnel for secure connectivity. Internet Gateway (Options A and C) is for public access, not VPNs, and NAT Gateway (Options A and B) is unrelated. Oracle’s VPN setup guide specifies DRG, CPE, and IPsec as the core components. The original answer (C) was incorrect; D is correct per OCI standards.

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 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.

For Oracle Interconnect for Google Cloud, users must select the Partner Interconnect Connection type when creating a VLAN attachment in the GCP console. This type integrates with OCI’s FastConnect via a partner network, enabling private connectivity. “Cross-Cloud Interconnect” (Option B) is not a GCP term, Dedicated Interconnect (Option C) is for direct GCP connections, and VPN (Option D) is unrelated. Oracle’s setup guide specifies Partner Interconnect for this multicloud link.

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.

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@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 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.

Oracle Database@Azure integrates with Azure Monitoring services to track database performance metrics such as block changes, OCPU utilization, and database wait time, which are critical for operational insights. Options like node status and ASM diskgroup utilization (A) are more infrastructure-focused, while invoice payments (B) and backup configurations (D) are unrelated toreal-time monitoring metrics. Oracle’s documentation on Database@Azure specifies these performance-oriented metrics as part of Azure’s monitoring capabilities.
