1Z0-1151-25 Exam Questions & Answers

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.

''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.

An existing Azure subscription is the foundational prerequisite for subscribing to Oracle Database@Azure, as the service is provisioned and billed through Azure. While a private interconnect (Option A) and linked OCI account (Option C) enhance functionality, they are not mandatory to initiate subscription---linking occurs post-subscription. A custom identity domain (Option D) is optional for federation but not a prerequisite. Oracle's subscription process documentation confirms this requirement.

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.

Oracle Database@Azure integrates with Azure Monitoring services to track database performance metrics such as block changes, OCPU utilization, and database wait time, which are critical for operational insights. Options like node status and ASM diskgroup utilization (A) are more infrastructure-focused, while invoice payments (B) and backup configurations (D) are unrelated to real-time monitoring metrics. Oracle's documentation on Database@Azure specifies these performance-oriented metrics as part of Azure's monitoring capabilities.
