A primary benefit of Oracle Autonomous Database on Shared Exadata Infrastructure is its ability to automatically tune and patch the database, reducing manual administration and improving performance and security. Option B is unrelated to the shared infrastructure model, Option C exaggerates storage (it’s scalable, not unlimited), and Option D is a general infrastructure feature, not specific to Autonomous Database. Oracle’s documentation highlights automation as a core advantage.

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.

“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.

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.

Oracle Database@Google Cloud is a multicloud service that integrates OCI database offerings into the Google Cloud Platform (GCP). According to official Oracle documentation, the Autonomous Database on Dedicated Infrastructure is a key service available in this offering. This service provides a fully managed database environment running on dedicated Exadata infrastructure, optimized for performance and isolation. The Base Database Service is a more basic offering not specifically highlighted in the Oracle Database@Google Cloud context, while HeatWave (listed twice in the original, corrected here as a single option) is a MySQL-focused analytics engine, not the primary native database service for this integration. The partnership between Oracle and Google Cloud, announced in June 2024, emphasizes Autonomous Database capabilities for enterprise workloads.

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.
