質問 # 22
What is the FINAL release supporting the non-CDB architecture?
- A. Oracle Database 21c
- B. Oracle Database 23c
- C. Oracle Database 18c
- D. Oracle Database 19c
正解：D
解説：
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.
質問 # 23
Which two statements are true when deciding which Oracle Cloud Infrastructure (OCI) region to register an Exadata Cloud@Customer infrastructure in?
- A. The Exadata Cloud@Customer region can be changed after the infrastructure is created
- B. Consider any business policies or regulations that preclude the use of a particular region
- C. Exadata Cloud@Customer is hosted in a customer data center so the Exadata infrastructure is not registered in an OCI region
- D. Consider the physical proximity of the region you register the infrastructure into your data center
正解：B、D
解説：
When registering "Exadata Cloud@Customer" in an OCI region, you must "consider any business policies or regulations that preclude the use of a particular region" (A), as compliance (e.g., data residency laws) dictates region selection. You should also "consider the physical proximity of the region you register the infrastructure into your data center" (D), as proximity reduces latency for control plane interactions. Option B is false because, despite being hosted on-premises, Exadata Cloud@Customer is registered in an OCI region for management. Option C is incorrect, as the region cannot be changed post-creation without significant reconfiguration. Oracle's documentation highlights these considerations for region selection.
質問 # 24
Which two actions can be performed from the OCI Console for an Oracle Autonomous Database?
- A. Scale up/down Memory
- B. Increase Network Bandwidth
- C. Increase Storage allocated for Database
- D. Scale up/down CPU
正解：C、D
解説：
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.
質問 # 25
Which two are true about the Autonomous JSON Database?
- A. Accessed via document APIs
- B. A DBA is required
- C. Applications cannot be built without SQL
- D. Instant auto-scaling
正解：A、D
解説：
The "Autonomous JSON Database" is "Accessed via document APIs" (A), such as SODA, for NoSQL-style operations, and offers "Instant auto-scaling" (D) for compute and storage with no downtime. "Applications cannot be built without SQL" (B) is false, as document APIs suffice, and "A DBA is required" (C) is incorrect due to its self-managing nature. Oracle's documentation highlights these autonomous and API-driven features.
質問 # 26
Oracle Cloud and Microsoft Azure have an interconnect for workloads across cloud. Which two are also benefits this partnership and interconnect provide?
- A. Connection to other multicloud environments
- B. Unified identity and access management
- C. Upgrade compliance
- D. Low Latency
正解：B、D
解説：
The Oracle Cloud and Microsoft Azure interconnect offers "Low Latency" (B), achieved through a high-speed, private connection between OCI and Azure data centers, reducing delays for cross-cloud workloads. 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 # 27
Which security measure is implemented out-of-the-box, and is included if you are not using BYOL licensing with Exadata Cloud@Customer?
- A. Oracle Key Vault
- B. Audit Vault and Database Firewall
- C. Oracle Native Network Encryption and TDE (Transparent Data Encryption)
- D. Database Vault and Data Masking Pack
正解：C
解説：
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 Database Firewall" (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.
質問 # 28
Oracle Data Lakehouse streamlines the integration, storage, and processing of dat a. Which two services are used for persistence of the data in Lakehouse?
- A. OCI Data Catalog
- B. OCI GoldenGate
- C. OCI Object Storage
- D. Autonomous Database
正解：C、D
解説：
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.
質問 # 29
Which command for the MySQL Data Service will resume OCPU billing?
- A. Backup
- B. Stop
- C. Start
- D. Restart
正解：C
解説：
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.

解説：
"Oracle Autonomous Database" accelerates innovation with: "Scaling of CPUs with very little downtime" (A), enabling dynamic performance adjustments online; "Built-in AI and ML helps find patterns that could identify undiscovered anomalies" (B), leveraging in-database machine learning; and "Instant scaling of storage" (C), providing flexibility without interruption. "Provisions a data warehouse in seconds" (D) is true but more a setup feature than an ongoing innovation driver. Oracle's documentation emphasizes these capabilities for rapid development and insights.
質問 # 31
What is NOT a workload that can be selected when provisioning an Autonomous Database?
- A. Data Warehouse
- B. JSON
- C. APEX
- D. MySQL
正解：D
解説：
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.
質問 # 32
Which Oracle Cloud Infrastructure storage platform is used by MySQL Database Service for all data storage?
- A. File Storage
- B. Block Volume Storage
- C. Archive Storage
- D. Object Storage
正解：B
解説：
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.
質問 # 33

Which three are required for provisioning an Oracle Autonomous Database instance?
- A. Workload Type
- B. Backup Location FRA Size
- C. Number of Tablespaces
- D. Number of CPUs
正解：A、B、D
解説：
Provisioning an "Oracle Autonomous Database" requires "Number of CPUs" (A) to define compute resources and "Workload Type" (D) (e.g., Transaction Processing, Data Warehouse) to configure the instance's purpose. "Number of Tablespaces" (B) is not specified (managed automatically), and "Backup Location FRA Size" (C) is not a user-defined parameter (backups are handled by Oracle). Oracle's provisioning documentation lists CPUs and workload type as mandatory.
質問 # 35

正解：C
質問 # 36
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 # 37
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. Each database comes with a REST-enabled compute instance to provide access to data
- D. A REST API is automatically generated on top of SQL or stored procedures
正解：D
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 # 38
What security control area determines if there is sensitive data in a system?
- A. Detect
- B. Protect
- C. Assess
- D. Users
正解：C
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.
質問 # 39
Which Oracle Cloud Infrastructure (OCI) service is NOT available as part of Oracle Cloud Free Tier?
- A. Autonomous Data Warehouse
- B. Monitoring
- C. Compute
- D. Exadata DB Systems

解説：
"Exadata DB Systems" (B) is not available in the Oracle Cloud Free Tier. The Free Tier includes "Autonomous Data Warehouse" (A) with limited resources, "Compute" (C) instances, and "Monitoring" (D) services, but Exadata DB Systems, being a high-performance, premium offering, requires a paid subscription. Oracle's Free Tier documentation lists eligible services, explicitly excluding Exadata.
質問 # 40
Which two methods can you use to create or modify Oracle Cloud Infrastructure (OCI) resources?
- A. OCI REST APIs
- B. OCI Command-line Interface (CLI)
- C. Remote Desktop Protocol (RDP)
- D. Secure Shell (SSH)
正解：A、B
解説：
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.
質問 # 41
Which ADB tool can you use to discover anomalies, outliers, and hidden patterns in your data?
- A. Catalog
- B. Data Load
- C. Data Insights
- D. Data Transforms
正解：C
解説：
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.
質問 # 42
What are the three security zones of control?
- A. Solve
- B. Prevent
- C. Assess
- D. Detect
正解：B、C、D
解説：
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.
質問 # 43
A customer wants to use Oracle Cloud Infrastructure (OCI) for storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?
- A. File Storage
- B. Object Storage (standard)
- C. Block Volume
- D. Archive Storage
正解：B
解説：
For storing application backups that need to be "stored for months, but retrieved immediately," "Object Storage (standard)" (A) is the suitable OCI service. Standard Object Storage offers durable, scalable storage with immediate access, ideal for backups requiring quick retrieval. "Archive Storage" (B) is cheaper but has retrieval delays, unsuitable for immediate access. "File Storage" (C) is for shared file systems, and "Block Volume" (D) is for high-performance attached storage, both less suited for long-term backups. Oracle's OCI Storage documentation confirms Standard Object Storage for this use case.
質問 # 44
Oracle Automated Machine Learning (AutoML) has options for using in-database and open-source algorithms. Which is an example of an in-database option?
- A. Cognitive text
- B. REST Interface
- C. Tuning of hyperparameter
- D. Oracle Machine Learning for Python (OML4PY) APIs
正解：D
解説：
An example of an in-database option in Oracle Automated Machine Learning (AutoML) is "Oracle Machine Learning for Python (OML4PY) APIs" (C). OML4Py enables Python-based machine learning directly within the database, leveraging in-database algorithms for performance and security. "REST Interface" (A) is an access method, "Cognitive text" (B) is a feature, not an algorithm type, and "Tuning of hyperparameter" (D) is a process, not a specific option. Oracle's documentation highlights OML4Py as a key in-database ML tool.
質問 # 45
Which feature allows you to logically group and isolate your Oracle Cloud Infrastructure resources?
- A. Tenancy
- B. Compartments
- C. Identity and Access Management Groups
- D. Availability Domain
正解：B
解説：
"Compartments" (B) in Oracle Cloud Infrastructure (OCI) allow you to logically group and isolate resources for organization, access control, and billing. "Identity and Access Management Groups" (A) organize users, not resources. "Tenancy" (C) is the root container for all resources, not a grouping mechanism, and "Availability Domain" (D) is a physical data center division, not a logical grouping tool. Oracle's OCI documentation identifies Compartments as the primary feature for resource isolation and management.
質問 # 46
Which workload CANNOT be run on Oracle Database 19c?
- A. Translytical
- B. Machine Learning
- C. Gaming
- D. Hadoop Clusters
正解：D
解説：
"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.
