1z0-1195-25 Oracle Data Platform 2025 Foundations Associate Questions and Answers

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.

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 "MySQL Database Service" on OCI uses "Block Volume Storage" (D) for all data storage, providing high-performance, persistent block storage attached to compute instances for database operations. "Object Storage" (A) is for unstructured data, "Flash Local Storage" (B) is temporary and instance-specific, and "File Storage" (C) is for shared file systems—none suit MySQL’s needs. Oracle’s MySQL Service documentation confirms Block Volume as the standard.

A prerequisite for running "APEX" (Application Express) on an Autonomous Database is provisioning "an Autonomous Database with the workload type Data Warehouse, TransactionProcessing, JSON, or APEX" (B). APEX is supported across these workload types, with ORDS (Oracle REST Data Services) pre-enabled. Option A is incorrect, as ORDS is automatically configured. Option C is too restrictive, as APEX isn’t limited to the APEX workload type alone. Option D is unnecessary, as user creation follows provisioning, not precedes it. Oracle’s Autonomous Database documentation confirms APEX availability across these workload types with no manual ORDS setup required.

The two main benefits of "Oracle APEX" (Application Express) include "Develop responsive web apps" (D), as it enables rapid creation of scalable, mobile-friendly applications using a low-code platform. The second benefit, though not perfectly listed, aligns with faster development (implied but misstated in A). "Faster development time using hand coding" (A) is incorrect, as APEX avoids hand coding with its declarative approach. "Less productivity compared to hand coding" (B) is false, as APEX increases productivity. "Store data in PL/SQL objects" (C) is a feature, not a primary benefit. Oracle’s APEX documentation emphasizes responsive web app development and rapid delivery as key advantages.

The "MySQL Database Service" on Oracle Cloud Infrastructure uses "Block Volume Storage" (C) for all data storage. Block Volume provides high-performance, persistent block storage that is directly attached to compute instances running the MySQL database, ensuring low-latency access for transactional and operational workloads. "Archive Storage" (A) is for long-term, infrequently accessed data, "Object Storage" (B) is for unstructured data, and "File Storage" (D) is for shared file systems—none of which suit the primary storage needs of a MySQL database. Oracle’s MySQL Database Service documentation confirms Block Volume as the default storage platform.

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.

The primary goal of "Oracle Maximum Availability Architecture" (MAA) is "Active Replication, Data Protection and continuous availability" (B). MAA is designed to ensure high availability and disaster recovery through active replication (e.g., Data Guard), data protection (e.g., backups), and continuous availability (minimal downtime). Option A includes "network security," which issecondary, not primary. Option C focuses on "reporting," which is unrelated, and D emphasizes "scale out," which is a feature, not the goal. Oracle’s MAA documentation defines these core objectives.

In the Oracle Cloud Infrastructure (OCI) Lakehouse, data processing capabilities are provided by services designed to handle computation and transformation of data. "Autonomous Database" (A) offers self-managing data processing for SQL workloads, "Big Data Service" (C) supports large-scale processing with Hadoop and Spark, and "OCI Data Flow" (D) enables serverless Spark processing. However, "NoSQL Service" (B) is primarily a storage service for unstructured key-value data, optimized for high-performance retrieval and scalability, not for general data processing tasks like transformation or analytics. Oracle’s Lakehouse documentation emphasizes processing services like Autonomous Database, Big Data Service, and OCI Data Flow, while NoSQL Service is positioned for persistence and access rather than processing.

The three security zones of control in Oracle’s security framework are "Assess" (A), for identifying risks and sensitive data, "Detect" (B), for monitoring and identifying threats, and "Prevent" (C), for implementing safeguards. "Solve" (D) is not a standard zone (perhaps intended as "Resolve," but still not part of the trio). Oracle’s security model, as seen in Data Safe and OCI, defines these as core zones.

"Compartments" (B) in Oracle Cloud Infrastructure (OCI) allow you to logically group and isolate resources for organization, access control, and billing. "Identity and Access Management Groups" (A) organize users, not resources. "Tenancy" (C) is the root container for all resources, not a grouping mechanism, and "Availability Domain" (D) is a physical data center division, not a logical grouping tool. Oracle’s OCI documentation identifies Compartments as the primary feature for resource isolation and management.

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.

"FastConnect" (D) is the interconnect solution to connect Oracle Cloud Infrastructure (OCI) to other cloud providers (e.g., Azure, AWS) via dedicated, high-speed links. "Virtual Cloud Network" (A) is an OCI internal network, "Virtual Private Cloud" (B) is an AWS term, and "Cloud Router" (C) is not a specific OCI offering (though third-party routers like Megaport exist). Oracle’s documentation confirms FastConnect for multicloud connectivity.

The "Oracle Autonomous Database" (B) offers the highest degree of security and governance with a self-service experience. It includes automated security features (e.g., TDE, network encryption), self-patching, and fine-grained access controls, all managed by Oracle, while allowing users to provision and manage databases independently. "Exadata Cloud Service" (A) provides high performance but requires more manual oversight. "Oracle Database Cloud Service" (C) offers flexibility but less automation, and "Oracle MySQL Database Service" (D) lacks the same level of autonomous security. Oracle’s documentation positions Autonomous Database as the pinnacle of secure, self-service deployment.
