Pass 1z0-1151-25 Exam Guide

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.

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.

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.

The Dedicated Deployment option for OCI Autonomous Database provides exclusive use of Exadata hardware, ensuring isolation and performance for critical workloads. Serverless (Option C) shares resources, while “Standalone” and “Exclusive” (Options A and B) are not standard OCI terms for this context. Oracle’s Autonomous Database documentation specifies Dedicated Deployment as the option for dedicated Exadata infrastructure.
