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

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.

For connections to multiple public clouds via 3rd-party connectivity, Oracle supports "Megaport Cloud Router (MCR) and Virtual Cross Connect (VXC)" (C). Megaport provides a cloud router and virtual cross-connects to link OCI with other clouds (e.g., AWS, Azure) through a global network. "Layer 3 and FastConnect" (A) is incomplete, "VCNs and Amazon VPC" (B) are internal constructs, and "FastConnect and Direct Connect" (D) are specific to Oracle and AWS, not a 3rd-party solution. Oracle’s multicloud connectivity documentation confirms Megaport’s role.

The "built-in SQL Worksheet and Notebook" (e.g., in Autonomous Database’s Database Actions) have two true statements: "No need to install a client query tool" (C), as it’s web-based and accessible via browser, and "Quickly start running queries with built-in web-based notebooks" (D), enabling immediate SQL execution. "Based on Apache Tomcat" (A) is not specified in documentation, and "Need to install client query tool for the PL/SQL" (B) is false due to its integrated nature. Oracle’s documentation confirms these web-based features.

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.

"Autonomous Transaction Processing" (ATP) is "used for OLTP and mixed workloads" (A), designed for high-performance transactional processing and hybrid workloads. "Data is stored in columnar format" (B) applies to Autonomous Data Warehouse, not ATP. "Used for analytic workloads" (C) is ADW’s focus, and "Used with data marts and machine learning" (D) is more ADW-specific. Oracle’s ATP documentation confirms its OLTP focus.

"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.

In a simple cloud management model (e.g., Autonomous Database), "Manage database servers and VM hosts" (A) is not the customer’s responsibility; Oracle handles infrastructure management.Customers "Subscribe to database servers" (B), manage "Everything inside of the database" (C) like data and schemas, and "Control access to customer VMs" (D) where applicable. Oracle’s shared responsibility model delegates server and host management to the provider.

ORDS stands for "Oracle REST Data Services," a middleware component provided by Oracle to enable RESTful access to Oracle Database and related services. It allows developers to expose SQL queries, database objects, and stored procedures as REST APIs, facilitating integration with modern applications. Options B ("Oracle Resilient Data Security"), C ("Oracle Rapid Data Systems"), and D ("Oracle REAP Diagnosis Systems") are not recognized terms in Oracle’s official documentation. ORDS is extensively documented in Oracle’s cloud and database resources as a critical tool for RESTful services, particularly in environments like Autonomous Database and Oracle Cloud Infrastructure (OCI).

For the "MySQL Database Service," the "Start" command (A) resumes OCPU billing, as it activates the database instance, incurring compute costs. "Stop" (B) halts billing by suspending the instance, "Restart" (C) is a stop-then-start sequence, and "Backup" (D) affects storage, not OCPU billing. Oracle’s MySQL Service documentation ties billing to the Start command.

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.

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.

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.

The Oracle-recommended way to upgrade databases is "AutoUpgrade" (D). AutoUpgrade automates the upgrade process, handling pre-checks, upgrades, and post-upgrade tasks with minimal manual intervention, reducing errors and downtime. "Database Upgrade Assistant (DBUA)" (A) is a GUI tool but less automated, "Data Pump Export/Import" (B) is for data migration, not direct upgrades, and "Command Line Upgrade" (C) is manual and error-prone. Oracle’s official upgrade guides endorse AutoUpgrade for its efficiency and reliability.

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.

Oracle’s "Converged Database" supports multiple data types/models, including "Spatial" (B) for geospatial data, "Graph" (D) for relationship analytics, and "Relational" (E) for traditional structured data. "Events" (A) is not a distinct data model but a use case, and "Terraform" (C) is an infrastructure tool, not a data type. Oracle’s documentation lists Spatial, Graph, and Relational among others (e.g., JSON, XML) as core converged capabilities.
