Question 1

What set of NoSQL-style APIs can be used in Autonomous JSON Database?

Accepted Answer

B

Explanation: The "Autonomous JSON Database" supports NoSQL-style document access through "SODA" (Simple Oracle Document Access) APIs (B). SODA provides a simple, intuitive interface for developers to interact with JSON documents stored in the database using operations like insert, query, and update, without requiring SQL knowledge. Options A ("OASD"), C ("DOSA"), and D ("OSDA") are not recognized API sets in Oracle’s documentation. SODA is explicitly documented as the standard NoSQL API for Autonomous JSON Database, aligning with Oracle’s converged database strategy to support multiple data models. Reference: Oracle Autonomous JSON Database Documentation, SODA Developer Guide.

Question 2

The Oracle Cloud Infrastructure (OCI) Data Catalog is an integral part of the Lakehouse solution. What
level of data detail does Data Catalog provide when integrated with Autonomous Databases and
Object Storage?

Accepted Answer

D

Explanation: 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. Reference: OCI Data Catalog Documentation, Oracle Lakehouse Integration Guide.

Question 3

Which Oracle Cloud Infrastructure storage platform is used by MySQL Database Service for all data storage?

Accepted Answer

D

Explanation: 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. Reference: OCI MySQL Database Service Architecture, Oracle Storage Options Guide.

Question 4

Which statements are true about built-in SQL Worksheet and Notebook? (Choose two)

Accepted Answer

C, D

Explanation: 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. Reference: Oracle Database Actions Guide, Autonomous Database Tools Documentation.

Question 5

In order to support multicloud strategies, what is offered as an industry first by Oracle?

Accepted Answer

D

Explanation: Oracle offers a "Dedicated cloud region" (D) as an industry-first feature to support multicloud strategies. This allows customers to run a fully managed OCI region within their own data center or a partner cloud, integrating with other providers like Azure or AWS. "Private and public cloud network" (A) is vague, "Cloud databases" (B) are common across vendors, and "Oracle FastConnect" (C) is a connectivity service, not unique to multicloud. Oracle’s documentation highlights the Dedicated Region as a pioneering multicloud solution. Reference: OCI Dedicated Region Overview, Oracle Multicloud Strategy White Paper.

Question 6

What are two main benefits of Oracle APEX?

Accepted Answer

D

Explanation: 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. Reference: Oracle APEX Overview, OCI Low-Code Development Guide.

Question 7

Which component is NOT included as part of an Oracle NoSQL table Oracle Cloud Identifier (OCID)?

Accepted Answer

C

Explanation: :

Question 8

What is the Oracle recommended way to upgrade databases?

Accepted Answer

D

Explanation: 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. Reference: Oracle AutoUpgrade Documentation, Database Upgrade Best Practices.

Question 9

Which command for the MySQL Data Service will resume OCPU billing?

Accepted Answer

A

Explanation: 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. Reference: OCI MySQL Database Service Guide, Oracle Billing Documentation.

Question 10

What three typical data types/models are covered by Oracle's Converged Database?

Accepted Answer

B, D, E

Explanation: 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. Reference: Oracle Converged Database White Paper, OCI Data Model Support.

Question 11

Which Oracle Cloud Infrastructure storage platform is used by MySQL Database Service for all data storage?

Accepted Answer

C

Explanation: 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. Reference: OCI MySQL Database Service Documentation, Oracle Storage Services Overview.

Question 12

Which two actions can be performed from the OCI Console for an Oracle Autonomous Database?

Accepted Answer

A, D

Explanation: From the OCI Console for an "Oracle Autonomous Database," you can "Scale up/down CPU" (A) to adjust compute resources dynamically and "Increase Storage allocated for Database" (D) to expand capacity, both with no downtime. "Increase Network Bandwidth" (B) is not a console-adjustable parameter (managed by Oracle), and "Scale up/down Memory" (C) is not independently configurable (tied to CPU scaling). Oracle’s documentation confirms CPU and storage scaling as user-controlled actions. Reference: Oracle Autonomous Database Scaling Guide, OCI Console Documentation.

Question 13

What are the two main features of APEX's low code platform?

Accepted Answer

D, F

Explanation: 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. Reference: Oracle APEX Features Overview, Oracle Low-Code Development Guide. Thank you for your visit.

Question 14

What is a prerequisite of running APEX on an Autonomous Database?

Accepted Answer

B

Explanation: A prerequisite for running "APEX" (Application Express) on an Autonomous Database is provisioning "an Autonomous Database with the workload type Data Warehouse, Transaction Processing, 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. Reference: Oracle Autonomous Database APEX Guide, OCI Provisioning Documentation.

Question 15

Oracle Lakehouse provides extensive data processing capabilities, to accommodate the migration of
existing architectures or the creation of new, agile ones. Which service does NOT provide data
processing on Oracle Cloud Infrastructure (OCI) Lakehouse?

Accepted Answer

B

Explanation: 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. Reference: OCI Lakehouse Architecture Guide, Oracle NoSQL Database Service Documentation.
