Oracle Oracle Data Platform 2025 Foundations Associate 1z0-1195-25 Exam Dumps: Updated Questions & Answers (May 2025)

Two important reasons to upgrade and patch are "Support Compliance" (A), ensuring the database remains under Oracle’s support policy with access to updates, and "Security" (C), applying patches to mitigate vulnerabilities and protect data. "Validation of application" (B) is a byproduct, not a primary reason, and "Restructure the database" (D) is unrelated to patching. Oracle’s maintenance guides emphasize compliance and security as key drivers.

The default configuration for automatic database backups in OCI (e.g., Autonomous Database) includes "Backups occur weekly" (A), with daily incremental and weekly full backups. "Archive redo log files are backed up every 30 minutes" (B) is not default (it’s real-time logging), "Retention period is set at 14 days" (C) is incorrect (default is 60 days), and "Backups are executed on primary site" (D) is vague but not a standard config statement. Oracle’s backup documentation specifies weekly full backups as default.

The final release supporting the "non-CDB (non-Container Database)" architecture is "Oracle Database 19c" (B). Oracle deprecated the non-CDB architecture starting with 20c (never fully released) and mandated the multitenant architecture (CDB with PDBs) from 21c onward. 19c, as a long-term support release, was the last to support non-CDB databases, with Oracle recommending migration to multitenant in subsequent versions like 23c. Oracle’s documentation confirms 19c as the end of non-CDB support.

The Oracle Cloud and Microsoft Azure interconnect offers "Low Latency" (B), achieved through a high-speed, private connection between OCI and Azure data centers, reducing delays for cross-cloud workloads. It also provides "Unified identity and access management" (C), integrating Oracle IAM with Azure Active Directory for seamless user authentication. "Upgrade compliance" (A) is vague and not a documented benefit, while "Connection to other multicloud environments" (D) is not specific to this partnership. Oracle’s multicloud documentation highlights latency and identity integration as key advantages.

The "Autonomous JSON Database" supports NoSQL-style document access through "SODA" (Simple Oracle Document Access) APIs (B). SODA provides a simple, intuitive interface for developers to interact with JSON documents stored in the database using operations like insert, query, and update, without requiring SQL knowledge. Options A ("OASD"), C ("DOSA"), and D ("OSDA") are not recognized API sets in Oracle’s documentation. SODA is explicitly documented as the standard NoSQL API for Autonomous JSON Database, aligning with Oracle’s converged database strategy to support multiple data models.

The most important reason to upgrade and patch is "Security" (A). Patches address vulnerabilities, protecting against exploits and ensuring compliance, which outweighs "Fix bugs" (C) in priority. "Restructure the database" (B) is unrelated to patching, and "Upgrading and patching the database is not important" (D) is false. Oracle’s security guidelines prioritize patching for protection.

In Oracle’s Data Lakehouse architecture, data persistence refers to the storage layer where data is durably maintained. "Autonomous Database" (B) provides a managed, self-tuning relational database for structured data persistence, supporting SQL-based workloads. "OCI Object Storage" (D) offers scalable, durable storage for unstructured and semi-structured data, such as files, images, and logs, serving as the data lake component of the Lakehouse. "OCI Data Catalog" (A) is a metadata management service, not a persistence layer, and "OCI GoldenGate" (C) handles data replication and integration, not direct storage. Oracle’s Lakehouse documentation identifies Autonomous Database and OCI Object Storage as the primary persistence services.

For "Exadata Cloud@Customer" without Bring Your Own License (BYOL), "Oracle Native Network Encryption and TDE (Transparent Data Encryption)" (D) are implemented out-of-the-box. Native Network Encryption secures data in transit, while TDE encrypts data at rest, both enabled by default to ensure baseline security compliance. "Oracle Key Vault" (A), "Audit Vault and DatabaseFirewall" (B), and "Database Vault and Data Masking Pack" (C) are advanced security options requiring additional configuration or licensing, not automatically included without BYOL. Oracle’s Exadata Cloud@Customer documentation confirms these encryption features as standard.

A "MySQL Database Service DB System" includes a "Compute Instance" (A) for processing, a "Virtual Network Interface" (B) for networking, and "Block Storage" (D) for data. "FastConnect" (C), a high-speed connectivity service to OCI, is not a component of the DB system itself but an optional external connection. Oracle’s MySQL Service documentation lists the core components, excluding FastConnect.

For serverless Spark processing in Oracle’s Lakehouse architecture, "OCI Data Flow" (C) is the designated service. OCI Data Flow is a fully managed, serverless platform that enables users to run Apache Spark applications without managing infrastructure, making it ideal for big data processing tasks like ETL, machine learning, and analytics. "Oracle Analytics Cloud" (A) is an analytics and visualization tool, not a Spark processing engine. "OCI Object Storage" (B) provides scalable storage but lacks processing capabilities, and "OCI Data Catalog" (D) is for metadata management, not Spark job execution. Oracle’s OCI documentation confirms OCI Data Flow as the primary service for serverless Spark workloads in the Lakehouse.
