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

For an Autonomous Database in Oracle Database@Google Cloud, backups are stored on Google Cloud Persistent Disks, which provide durable, block-level storage within GCP. OCI Object Storage (Option B) is used for OCI-native deployments, not this Google Cloud-integrated service. Google Cloud Filestore (Option C) is for file storage, not database backups. This is specified in Oracle’s documentation for Database@Google Cloud.

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.

Oracle Database@Azure allows provisioning of Exadata Infrastructure through the Azure portal and APIs, integrating seamlessly with Azure’s management ecosystem. The OCI console (Option A) and OCI Terraform scripts (Option B) are not used for this Azure-native service. Azure Terraform scripts (Option C) are possible but not the primary interface highlighted in Oracle’s documentation, which emphasizes the Azure portal/APIs.

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.

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.

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.

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.

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.

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.

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.

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.

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.

“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.

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.

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.

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.
