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

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.

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.

For Oracle Database@Google Cloud, customers consult Oracle Sales to create a private offer in the Google Cloud Marketplace, aligning with the service’s GCP integration. Option A incorrectly references OCI Marketplace, Option C misstates account requirements (an OCI account links post-purchase), and Option D skips the sales consultation step. Oracle’s purchasing process documentation supports this for GCP-based services.

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.

The “Oracle Public Cloud” typically refers to OCI’s broadly accessible cloud services. Autonomous Database on Shared (Option A) and Dedicated Infrastructure (Option B) are available in OCI. However, Exadata Database Service on Dedicated Infrastructure (Option C) is not a standard offering in the public OCI context—it’s tied to specific deployments like Database@Azure or on-premises Exadata, not the public cloud. Option D is fictitious. Oracle’s documentation clarifies Exadata’s dedicated nature outside standard public offerings.

The connectivity link between the OCI child site (in GCP) and parent site (OCI) supports control plane operations (e.g., infrastructure management) and data plane operations (e.g., backups, DR) via the dark fiber network. Options A, C, and D are unrelated to this technical function. Oracle’s multicloud architecture docs specify this dual-purpose link.

Azure Monitoring services are used to monitor and analyze Oracle Exadata VM Cluster metrics in the Oracle Database@Azure service, integrating seamlessly with Azure’s ecosystem. Microsoft Defender (Option A) is a security tool, not for performance monitoring. OCI Monitoring (Option D) is separate, and no specific “Oracle Database Management Tool” (Option B) is highlighted for this purpose in Azure. Oracle’s multicloud docs confirm Azure Monitoring’s role.

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.

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.

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.

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.

In Oracle Database@Azure, the Azure portal is used for managing and maintaining Exadata VM clusters and infrastructure, aligning with its Azure-native management approach. Data Guard (Option A), database homes (Option B), and container/pluggable databases (Option D) are configured post-provisioning, often via database tools, not directly as portal tasks. Oracle’s documentation specifies this infrastructure focus in Azure.

Private peering in OCI FastConnect connects on-premises networks to a VCN using private IPs, while public peering connects to Oracle’s public services (e.g., Object Storage) via public IPs, avoiding the internet. Option A is false—they can coexist. Option B misstates the network usage, and Option D reverses the definitions. Oracle’s FastConnect documentation clearly defines these roles.
