1z0-1195-25 Exam Dumps - Oracle Cloud Infrastructure Questions and Answers

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.

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.

Full Detailed In-Depth Explanation: Oracle APEX (Application Express) is a leading low-code platform designed to simplify and accelerate application development, particularly within the Oracle ecosystem. The two main features of APEX’s low-code platform are "Use graphical user interfaces and configuration" (D) and "Focus on business requirements" (F). Option D reflects APEX’s core strength: it provides a browser-based, declarative development environment with drag-and-drop functionality, wizards, and visual UI tools, allowing developers and business users to build applications with minimal coding. This reduces complexity and speeds up development, aligning with the low-code philosophy. Option F highlights APEX’s emphasis on enabling users to address business needs directly, rather than getting bogged down in technical intricacies, by offering prebuilt components and templates tailored to solve real-world problems efficiently. "Limited productivity" (A) is incorrect, as APEX enhances productivity significantly. "Build scalable web apps for MongoDB" (B) is false, as APEX is optimized for Oracle Database, not MongoDB. "Simplified core-based licensing" (C) is a licensing aspect, not a development feature, and "Use traditional computer programming paradigms" (E) contradicts APEX’s low-code approach, which minimizes hand-coding. Oracle’s official APEX documentation emphasizes its graphical, business-focused design as key differentiators.

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 "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.

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.

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.

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.

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.
