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

For Oracle Database@Azure, enabling automatic backups to OCI Object Storage and configuring Oracle Data Guard with local and remote standby databases ensures both automated backups and high availability (HA). Data Guard provides HA by maintaining synchronized standby databases, while automatic backups to OCI Object Storage (despite the Azure context) ensure recovery. Options A, B, and C either skip automation or rely on manual/third-party solutions, which are less integrated and efficient. Oracle’s documentation confirms this hybrid approach for HA and backup in multicloud setups.

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.

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 key difference is that private offers for Oracle Database@Google Cloud require negotiation with an Oracle sales representative to create a tailored contract in the Google Cloud Marketplace, whereas public offers are standardized and directly available without negotiation. Option D is incorrect; both are billed through Google Cloud. Options A and B misrepresent the workflows. Oracle’s purchasing documentation outlines this sales-driven process for private offers.

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.

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.

FastConnect with an Oracle partner uses a third-party network to connect to OCI, while colocation with Oracle involves a direct physical connection at an OCI data center. The difference lies in the physical connection method, not locations (Option A), redundancy (Option B), or circuits (Option C). Oracle’s FastConnect documentation outlines these deployment models.

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.

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.

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 Oracle Base Database Service in OCI leverages Availability Domains (ADs) and Fault Domains (FDs) to ensure high availability (HA) and disaster recovery (DR). ADs are isolated data centers within a region, preventing single points of failure, while FDs are subdivisions within an AD, further isolating hardware for redundancy. Availability Sets and Zones (Options A and B) are Azure-specific terms, and Geography (Option C) is too vague. OCI’s architecture documentation confirms ADs and FDs as the foundation for HA/DR in database 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.

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.

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 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.

An Identity Provider (IdP) in OCI federation is a service that authenticates users and provides their identity credentials, such as Microsoft Entra ID or another SAML-compliant provider. It doesn’t merely call a service provider (Option A) or act as a protocol (Option B—e.g., SAML is the protocol, not the IdP). It’s also distinct from OCI’s internal resource management components (Option D), like IAM. OCI’s identity federation documentation defines the IdP’s role in enabling single sign-on (SSO) across clouds.
