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

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.

"Exadata" integrates software and hardware and is available both "In the Oracle Cloud and customer site" (D). It is offered as Exadata Cloud Service (public cloud) and Exadata Cloud@Customer (on-premises), providing flexibility for hybrid deployments. "Only in a hybrid cloud" (A) is too restrictive, "Only in public cloud environments" (B) ignores Cloud@Customer, and "Only at the customer site" (C) excludes the cloud option. Oracle’s documentation confirms Exadata’s availability in both OCI and on-premises configurations.

The "Autonomous Database" offers self-service tools like "Oracle Machine Learning" (B), enabling users to build ML models directly in the database, and "Low-Code App Dev, APEX" (C), allowing rapid application development via Oracle APEX. "Business Objects" (A) is a third-party BI tool, not native to ADB, and "Encryption only in Object Storage" (D) is a feature, not a tool, and inaccurate (encryption is broader). Oracle’s documentation highlights OML and APEX as key self-service capabilities.

"Oracle Exadata Cloud Service" (B) offers expanded flexibility with shared or dedicated Exadata infrastructure, allowing customers to choose between cost-effective shared resources or isolated dedicated hardware for performance and compliance needs. "Oracle Database Cloud Service" (A) is VM-based and lacks Exadata’s hardware integration, "Oracle Autonomous Database" (C) is fully managed without hardware choice, and "Oracle Exalogic Cloud Service" (D) is an outdated middleware platform, not database-focused. Oracle’s documentation highlights Exadata Cloud Service’s deployment options.

"Oracle Database 19c" supports "Machine Learning" (A) via in-database algorithms, "Translytical" (B) workloads combining transactional and analytical processing, and "Gaming" (C) through high-performance transaction support. However, "Hadoop Clusters" (D) cannot run directly on 19c, as Hadoop is a distributed framework requiring a separate ecosystem (e.g., Oracle Big Data Service), not a workload natively supported within the database engine. Oracle’s 19c documentation details its converged database capabilities, excluding Hadoop as a direct workload.

For an "Autonomous Database," the DBA can "Open the database in OCI Console and increase the number of OCPU. No downtime required" (C). Autonomous Database supports dynamic scaling of OCPUs online, with no service interruption, leveraging its self-managing capabilities. Options A and B involve unnecessary downtime, and D adds an unneeded user restriction. Oracle’s documentation confirms zero-downtime OCPU scaling as a key feature.

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.

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 "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.

"Logical Migration" (B) uses "Datapump" for exporting/importing database objects and "GoldenGate" for real-time replication, focusing on data and schema transfer rather than physical structures. "Physical Migration" (A) involves moving entire database files (e.g., RMAN), while "Direct Connection" (C) and "Indirect Connection" (D) are not standard migration types. Oracle’s migration guides associate Datapump and GoldenGate with logical methods.

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.

"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.

When registering "Exadata Cloud@Customer" in an OCI region, you must "consider any business policies or regulations that preclude the use of a particular region" (A), as compliance (e.g., data residency laws) dictates region selection. You should also "consider the physical proximity of the region you register the infrastructure into your data center" (D), as proximity reduces latency for control plane interactions. Option B is false because, despite being hosted on-premises, Exadata Cloud@Customer is registered in an OCI region for management. Option C is incorrect, as the region cannot be changed post-creation without significant reconfiguration. Oracle’s documentation highlights these considerations for region selection.

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.
