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

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.

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 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.

HeatWave in OCI’s MySQL Database Service is a distributed in-memory query accelerator, enhancing analytical query performance for MySQL workloads. It’s not primarily for migration (Option B), HA (Option C), or serverless deployment (Option D), though it integrates with HA features. Oracle’s HeatWave documentation highlights its in-memory acceleration focus.

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 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 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.

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.

Oracle Database@Google Cloud offers Public and Private purchase options via the Google Cloud Marketplace. Public offers are standardized and directly available, while Private offers involve negotiated terms with Oracle Sales. Options A and C are not official terms, and Free Tier (Option D) doesn’t apply to this enterprise service. Oracle’s purchasing documentation defines these two types.

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.

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.

Configuring the Oracle Interconnect for Google Cloud requires Virtual Circuits on OCI (via FastConnect) and Partner Interconnects on GCP, establishing a private, high-speed link between the clouds. A direct internet connection (Option A) defeats the purpose of a private interconnect, while Microsoft Active Directory (Option B) is unrelated to network setup. Public subnets (Option D) are not required—private connectivity is the goal. This setup is detailed in Oracle’s multicloud networking documentation.

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.
