Oracle Updated 1z0-1195-25 Exam Questions and Answers by arnie

The Exadata X8M leverages "Remote Direct Memory Access" (RDMA) to access "Persistent Memory" (B). RDMA allows direct memory-to-memory data transfer between systems without CPU involvement, enhancing performance. In Exadata X8M, RDMA accesses persistent memory (PMEM) to accelerate database operations by reducing latency and improving I/O throughput. "Compute Instances" (A) and "Database Servers" (D) are broader entities, not the specific resource RDMA targets, while "Storage Disks" (C) are traditional storage, not memory. Oracle’s Exadata documentation highlights RDMA’s use with persistent memory in X8M systems.

When provisioning an "Autonomous Database" on Oracle Cloud Infrastructure, the supported workload types include "JSON" (B) for document-centric applications, "Data Warehouse" (C) for analytics, and "APEX" (D) for low-code application development, alongside Transaction Processing (not listed here). "MySQL" (A) is not a workload type for Autonomous Database; instead, it is a separate database service (Oracle MySQL Database Service) on OCI, not part of the Autonomous Database offering. Oracle’s documentation specifies the distinct workload options available during Autonomous Database provisioning, excluding MySQL.

The "Converged Database" facilitates API access by "A REST API is automatically generated on top of SQL or stored procedures" (B), using Oracle REST Data Services (ORDS). This allows developers to expose database logic as RESTful endpoints without manual coding. Option A is incorrect, as no separate compute instance is provided. Option C oversimplifies, as multiple REST interfaces can be created, not just one. Option D misrepresents the ADB Wallet’s role, which is for security, not API generation. Oracle’s documentation highlights ORDS auto-generation as a converged feature.

For storing application backups that need to be "stored for months, but retrieved immediately," "Object Storage (standard)" (A) is the suitable OCI service. Standard Object Storage offers durable, scalable storage with immediate access, ideal for backups requiring quick retrieval. "ArchiveStorage" (B) is cheaper but has retrieval delays, unsuitable for immediate access. "File Storage" (C) is for shared file systems, and "Block Volume" (D) is for high-performance attached storage, both less suited for long-term backups. Oracle’s OCI Storage documentation confirms Standard Object Storage for this use case.
