At ValidExamDumps, we consistently monitor updates to the Oracle 1Z0-1151-25 exam questions by Oracle. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Oracle Cloud Infrastructure 2025 Multicloud Architect Professional exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Oracle in their Oracle 1Z0-1151-25 exam. These outdated questions lead to customers failing their Oracle Cloud Infrastructure 2025 Multicloud Architect Professional exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Oracle 1Z0-1151-25 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
What is the primary function of the connectivity link between the OCI child site and the OCI parent site in the context of Oracle Database@Google Cloud?
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.
A company XYZ has been using Oracle Cloud Infrastructure to host their mission-critical applications, but they have decided to start using Azure for some of their workloads. They want to enable connectivity between their Oracle Cloud Infrastructure and Microsoft Azure to create a multicloud architecture.
The OCI-Azure Interconnect is the official Oracle-Microsoft partnership solution for establishing a private, high-bandwidth, and low-latency connection between OCI and Azure. This interconnect leverages Azure ExpressRoute and Oracle FastConnect to create a dedicated network link, bypassing the public internet for enhanced security and performance. A VPN connection (Option A) is possible but less optimal due to higher latency and lower reliability compared to the interconnect. Using the public internet (Option B) is insecure and unsuitable for mission-critical applications. This solution is detailed in Oracle's multicloud architecture guides and the OCI-Azure partnership documentation, emphasizing its suitability for enterprise multicloud deployments.
To achieve high availability in a 2-node RAC DB System in Oracle Cloud Infrastructure, what would you use to distribute your nodes to provide database instance fault isolation?
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.
How are the resources provisioned in Oracle Database@Azure service?
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.
Which statement accurately describes the difference between public peering and private peering in OCI FastConnect?
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.
