1z0-1151-25 Exam Dumps - Oracle Cloud Infrastructure Questions and Answers

The connectivity link between the OCI child site (in GCP) and parent site (OCI) supports control plane operations (e.g., infrastructure management) and data plane operations (e.g., backups, DR) via the dark fiber network. Options A, C, and D are unrelated to this technical function. Oracle’s multicloud architecture docs specify this dual-purpose link.

Oracle Database@Azure allows customers to provision and manage Oracle database resources directly within the Azure portal, streamlining multicloud operations. Specifically, the Oracle Exadata Infrastructure and Exadata VM Cluster are provisioned through Azure, integrating OCI database capabilities into the Azure ecosystem. Options involving the OCI console (B and C) are incorrect because this service is designed for Azure-native management. Option D overextends by including container and pluggable databases, which are managed post-provisioning, not part of the initial infrastructure setup in Azure. This is detailed in the Oracle Database@Azure service documentation.

Private peering in OCI FastConnect connects on-premises networks to a VCN using private IPs, while public peering connects to Oracle’s public services (e.g., Object Storage) via public IPs, avoiding the internet. Option A is false—they can coexist. Option B misstates the network usage, and Option D reverses the definitions. Oracle’s FastConnect documentation clearly defines these roles.

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.

Oracle FastConnect uses Border Gateway Protocol (BGP) to dynamically exchange routing information between on-premises networks and OCI, ensuring optimal path selection. OSPF (Option A) and RIP (Option C) are not used, and static routing (Option D) is an option but not the default or dynamic method. Oracle’s FastConnect documentation confirms BGP as standard. The original question’s placeholder has been replaced with BGP as the correct answer.

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.
