Pass the Oracle Oracle Cloud Infrastructure 1z0-1151-25 Questions and answers with CertsForce

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.

Setting up the Oracle virtual circuit for OCI-Azure Interconnect requires both primary andsecondary pairs of BGP IP addresses to ensure redundancy and failover in dynamic routing. A single pair (Option A) lacks resilience, no BGP (Option B) contradicts the interconnect’s routing design, and a secondary-only pair (Option D) is incomplete. Oracle’s networking guide mandates this dual-pair configuration.

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.

An Identity Provider (IdP) in OCI federation is a service that authenticates users and provides their identity credentials, such as Microsoft Entra ID or another SAML-compliant provider. It doesn’t merely call a service provider (Option A) or act as a protocol (Option B—e.g., SAML is the protocol, not the IdP). It’s also distinct from OCI’s internal resource management components (Option D), like IAM. OCI’s identity federation documentation defines the IdP’s role in enabling single sign-on (SSO) across clouds.

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.
