Oracle 1z0-1151-25 Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Exam Practice Test

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.

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.

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 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 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.

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.

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.

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.

In Oracle Database@Azure, delegated subnets from an Azure VNet are linked to the OCI VCN within OCI pods during the provisioning of the Oracle Exadata VM Cluster. This step occurs in the Azure portal when you specify subnet details, enabling the Exadata infrastructure to communicate with Azure resources. Option A is incorrect as container databases are provisioned later in OCI, not Azure. Option B misplaces this as a prerequisite during account linking, and Option C is too vague, as it references the broader service rather than the specific VM Cluster step. Oracle’s provisioning guide confirms this timing.

“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.

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 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.

The Dedicated Deployment option for OCI Autonomous Database provides exclusive use of Exadata hardware, ensuring isolation and performance for critical workloads. Serverless (Option C) shares resources, while “Standalone” and “Exclusive” (Options A and B) are not standard OCI terms for this context. Oracle’s Autonomous Database documentation specifies Dedicated Deployment as the option for dedicated Exadata infrastructure.

Oracle FastConnect uses Border Gateway Protocol (BGP) to dynamically exchange routing information between on-premises networks and OCI, ensuring optimal path selection. OSPF (Option A) and RIP (Option C) are not used, and static routing (Option D) is an option but not the default or dynamic method. Oracle’s FastConnect documentation confirms BGP as standard. The original question’s placeholder has been replaced with BGP as the correct answer.

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.
