Curious about Actual Oracle Database (1Z0-1195-25) Exam Questions?

Correct : D

The 'OCI Data Catalog' provides a 'View of data for discovery' (D) when integrated with Autonomous Databases and OCI Object Storage in the Lakehouse solution. It serves as a metadata management service, offering a centralized view of data assets, their schemas, and relationships, enabling users to discover and understand data across the Lakehouse. 'Analytic environments' (A) and 'Data Warehouse' (B) refer to processing or storage constructs, not the role of Data Catalog. 'Source of managed services' (C) is vague and not a documented function. Oracle's documentation highlights Data Catalog's role in data discovery and governance, not processing or storage.

Correct : B, C

'Oracle SQLcl' (SQL Developer Command Line) is a lightweight, command-line interface for interacting with Oracle Databases. It has two key characteristics: 'Tracks database schema changes' (B), through integration with tools like Liquibase, allowing DBAs to monitor and manage schema evolution; and 'Ability to execute SQL batch files' (C), enabling automation of multiple SQL statements in scripts. 'Creates isolated development environments' (A) is not a feature of SQLcl, as it's a client tool, not a virtualization platform. 'Available in the OCI Cloud Shell by default' (D) is incorrect, as OCI Cloud Shell provides a general terminal but does not pre-install SQLcl. Oracle's SQLcl documentation confirms these capabilities.

Correct : A

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.

Correct : C

Correct : B

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.
