Free Practice Questions for Oracle 1z0-1151-25 Exam

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@Azure allows provisioning of Exadata Infrastructure through the Azure portal and APIs, integrating seamlessly with Azure’s management ecosystem. The OCI console (Option A) and OCI Terraform scripts (Option B) are not used for this Azure-native service. Azure Terraform scripts (Option C) are possible but not the primary interface highlighted in Oracle’s documentation, which emphasizes the Azure portal/APIs.

Border Gateway Protocol (BGP) is a dynamic routing protocol used in the OCI-Azure Interconnect to automatically determine the optimal path for data between an Azure Virtual Network (VNet) and an OCI Virtual Cloud Network (VCN). Unlike static routing (Option A), BGP adapts to network changes, ensuring efficient and reliable connectivity. It doesn’t establish the connection itself(Option B) or manage security rules (Option C)—those are handled by FastConnect/ExpressRoute and security lists, respectively. Oracle’s networking documentation for multicloud interconnects confirms BGP’s role in route optimization.

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.

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.

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.
