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

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.

Drivers for adopting multicloud architectures typically include redundancy/disaster recovery (ensuring availability across providers), best-of-breed cloud services (leveraging specialized offerings), and cost optimization (balancing expenses across clouds). A Content Delivery Network (CDN) is a specific service for distributing content globally, often provided by cloud vendors, but it is not a strategic driver for adopting a multicloud approach. CDNs can be used within a single cloud or multicloud setup, but they don’t inherently motivate the decision to use multiple clouds. Oracle’s multicloud strategy documentation highlights the other three as primary motivations.

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.

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.

OCI Site-to-Site VPN connections use Internet Protocol Security (IPsec) to secure data transmission, providing encryption and authentication over the tunnel. SSL (Option A) and TLS (Option C) are typically used for web traffic, not VPNs, while DTLS (Option B) is designed for datagram-based applications, not standard VPNs. Oracle’s VPN documentation specifies IPsec as the protocol, aligning with industry standards for secure VPNs. The original question incorrectly listed SSL as the answer; IPsec is correct per OCI standards.

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.

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.

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 OCI-Azure Interconnect is the official Oracle-Microsoft partnership solution for establishing a private, high-bandwidth, and low-latency connection between OCI and Azure. This interconnect leverages Azure ExpressRoute and Oracle FastConnect to create a dedicated network link, bypassing the public internet for enhanced security and performance. A VPN connection (Option A) is possible but less optimal due to higher latency and lower reliability compared to the interconnect. Using the public internet (Option B) is insecure and unsuitable for mission-critical applications. This solution is detailed in Oracle’s multicloud architecture guides and the OCI-Azure partnership documentation, emphasizing its suitability for enterprise multicloud deployments.
