It also provides "Unified identity and access management" (C), integrating Oracle IAM with Azure Active Directory for seamless user authentication. "Upgrade compliance" (A) is vague and not a documented benefit, while "Connection to other multicloud environments" (D) is not specific to this partnership. Oracle's multicloud documentation highlights latency and identity integration as key advantages.
質問 # 34
What self-service tools are available with the Autonomous Database?
- A. Encryption only in Object Storage
- B. Low-Code App Dev, APEX
- C. Business Objects
- D. Oracle Machine Learning
正解：B、D
解説：
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.
質問 # 35
What set of NoSQL-style APIs can be used in Autonomous JSON Database?
- A. OASD (Oracle Application Storage Definition)
- B. OSDA (Oracle Simple Document Access)
- C. DOSA (Document Open Solution Access)
- D. SODA (Simple Oracle Document Access)
正解：D
解説：
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.
質問 # 36
What is a prerequisite of running APEX on an Autonomous Database?
- A. A DBA must enable ORDS first
- B. APEX can only be used when selecting APEX as a workload when provisioning an Autonomous Database
- C. An Autonomous Database with the workload type Data Warehouse, Transaction Processing, JSON, or APEX
- D. DBA must create APEX admin and APEX users first before starting APEX from Oracle Cloud Infrastructure Console
正解：C
解説：
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.

正解：A
解説：
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.
質問 # 38
The DBA has determined that the number of OCPU assigned to an Autonomous Database does not provide sufficient performance. Which option does the DBA have in this case?
- A. No downtime is required as number of OCPU can be increased from OCI console, but users have to be informed that they must not use any application for at least one hour
- B. Plan for a one-hour downtime and increase the number of OCPU while database is offline
- C. Open the database in OCI Console and increase the number of OCPU. No downtime required
- D. Call Oracle Cloud Support and raise a request to increase number of OCPU. Expect a downtime of approximately one hour
正解：C
解説：
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.
質問 # 39
What does ORDS stand for?
- A. Oracle Resilient Data Security
- B. Oracle Rapid Data Systems
- C. Oracle REAP Diagnosis Systems
- D. Oracle REST Data Services
正解：D
解説：
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).

"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.
質問 # 43
What is the most important reason to upgrade and patch?
- A. Security
- B. Upgrading and patching the database is not important
- C. Fix bugs
- D. Restructure the database
正解：A
解説：
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.
質問 # 44
Which migration type uses Datapump and GoldenGate tools?
- A. Direct Connection
- B. Indirect Connection
- C. Logical Migration
- D. Physical Migration
正解：C
解説：
"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.
質問 # 45
What are two important reasons to upgrade and patch?
- A. Support Compliance
- B. Security
- C. Validation of application
- D. Restructure the database
正解：A、B
解説：
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.
質問 # 46
How does the Converged Database help to access data using an API?
- A. Developers can point their application to the location of ADB Wallet which integrates all REST API calls
- B. The database provides only one universal REST interface which makes integration of applications extremely agile
- C. A REST API is automatically generated on top of SQL or stored procedures
- D. Each database comes with a REST-enabled compute instance to provide access to data
正解：C
解説：
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.
質問 # 47
What is the Oracle recommended way to upgrade databases?
- A. Database Upgrade Assistant (DBUA)
- B. AutoUpgrade
- C. Data Pump Export/Import
- D. Command Line Upgrade
正解：B
解説：
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.

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.
質問 # 49
What security control area determines if there is sensitive data in a system?
- A. Assess
- B. Users
- C. Protect
- D. Detect
正解：A
解説：
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.
