Oracle 1z0-1195-25 Oracle Data Platform 2025 Foundations Associate Exam Practice Test

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.

"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 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.

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.

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 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.

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.

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.

In the Autonomous Database (ADB), "Data Insights" (B) is the tool to discover anomalies, outliers, and hidden patterns, leveraging built-in AI and ML capabilities to analyze data. "Data Load" (A) is for importing data, "Data Transforms" (C) is for data preparation, and "Catalog" (D) is for metadata (OCI Data Catalog). Oracle’s documentation identifies Data Insights for pattern detection.

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.

"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.

To create or modify Oracle Cloud Infrastructure (OCI) resources, "OCI REST APIs" (A) and "OCI Command-line Interface (CLI)" (C) are two primary methods. OCI REST APIs allow programmatic management of resources via HTTP requests, while the OCI CLI provides a command-line tool for scripting and automation. "Remote Desktop Protocol (RDP)" (B) is for accessing Windows-based systems, not OCI resource management, and "Secure Shell (SSH)" (D) is for accessing compute instances, not broadly creating or modifying resources. Oracle’s OCI documentation confirms REST APIs and CLI as standard management tools.

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.

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.

In Oracle’s security framework, the "Assess" security control area (C) is responsible for determining whether sensitive data exists within a system. This phase involves data discovery, classification, and risk analysis to identify sensitive information such as PII or financial data. "Users" (A) relates to access management, "Detect" (B) focuses on identifying threats or breaches, and "Protect" (D) involves implementing safeguards—none of these directly address the initial identification of sensitive data. Oracle’s Data Safe and OCI security documentation highlight "Assess" as the key stage for sensitive data discovery, often leveraging tools like Data Catalog or Data Safe.

Customers may not move databases to the public cloud due to "Putting data in the cloud would break data residency rules" (A), where laws mandate data remain in specific regions, and "Regulations that prevent moving data into the public cloud" (B), such as industry-specific compliance requirements (e.g., GDPR, HIPAA). "Total Cost of Ownership in public cloud is higher" (C) is a consideration but not a universal barrier, and "Public cloud does not provide storage for more than 10TB" (D) is false, as OCI offers vast storage options. Oracle’s cloud adoption guides cite residency and regulatory constraints as common blockers.

For migrating "old database backups" to OCI, "Archive Storage" (D) is the most cost-effective service. Archive Storage offers the lowest cost per gigabyte for long-term, infrequently accessed data, ideal for backups that don’t require immediate retrieval. "Object Storage (standard)" (A) is more expensive and suited for frequent access, "Block Volume" (B) is high-performance and costly, and "File Storage" (C) is for active file systems. Oracle’s storage pricing and use case documentation recommend Archive Storage for cost-effective backup archival.

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.
