"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 # 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. Open the database in OCI Console and increase the number of OCPU. No downtime required
- B. Call Oracle Cloud Support and raise a request to increase number of OCPU. Expect a downtime of approximately one hour
- C. 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
- D. Plan for a one-hour downtime and increase the number of OCPU while database is offline
正解：A
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 security control area determines if there is sensitive data in a system?
- A. Detect
- B. Assess
- C. Protect
- D. Users
正解：B
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.

- 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 # 41
Exadata is the integration of software and hardware and is available to customers on which deployments?
- A. In the Oracle Cloud and customer site
- B. Only in a hybrid cloud
- C. Only at the customer site
- D. Only in public cloud environments
正解：A
解説：
"Exadata" integrates software and hardware and is available both "In the Oracle Cloud and customer site" (D). It is offered as Exadata Cloud Service (public cloud) and Exadata Cloud@Customer (on-premises), providing flexibility for hybrid deployments. "Only in a hybrid cloud" (A) is too restrictive, "Only in public cloud environments" (B) ignores Cloud@Customer, and "Only at the customer site" (C) excludes the cloud option. Oracle's documentation confirms Exadata's availability in both OCI and on-premises configurations.
質問 # 42
What is a prerequisite of running APEX on an Autonomous Database?
- A. An Autonomous Database with the workload type Data Warehouse, Transaction Processing, JSON, or APEX
- B. A DBA must enable ORDS first
- C. APEX can only be used when selecting APEX as a workload when provisioning an Autonomous Database
- D. DBA must create APEX admin and APEX users first before starting APEX from Oracle Cloud Infrastructure Console
正解：A
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.
質問 # 43
Which statement is not the responsibility of the customer in a simple cloud management model?
- A. Everything inside of the database
- B. Subscribe to database servers
- C. Manage database servers and VM hosts
- D. Control access to customer VMs
正解：C
解説：
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.
質問 # 44
Which statement is true about Autonomous Transaction Processing?
- A. It is used for OLTP and mixed workloads
- B. Data is stored in columnar format
- C. It is used with data marts and machine learning
- D. It is used for analytic workloads
正解：A
解説：
"Autonomous Transaction Processing" (ATP) is "used for OLTP and mixed workloads" (A), designed for high-performance transactional processing and hybrid workloads. "Data is stored in columnar format" (B) applies to Autonomous Data Warehouse, not ATP. "Used for analytic workloads" (C) is ADW's focus, and "Used with data marts and machine learning" (D) is more ADW-specific. Oracle's ATP documentation confirms its OLTP focus.
質問 # 45
Which two statements are true when deciding which Oracle Cloud Infrastructure (OCI) region to register an Exadata Cloud@Customer infrastructure in?
- A. Consider the physical proximity of the region you register the infrastructure into your data center
- B. Consider any business policies or regulations that preclude the use of a particular region
- C. The Exadata Cloud@Customer region can be changed after the infrastructure is created
- D. Exadata Cloud@Customer is hosted in a customer data center so the Exadata infrastructure is not registered in an OCI region
正解：A、B
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 # 46
What does ORDS stand for?
- A. Oracle REAP Diagnosis Systems
- B. Oracle Rapid Data Systems
- C. Oracle REST Data Services
- D. Oracle Resilient Data Security
正解：C
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).

- A. Backups are executed on primary site
- B. Archive redo log files are backed up every 30 minutes
- C. Retention period is set at 14 days
- D. Backups occur weekly
正解：D
解説：
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.
質問 # 48
Which migration type uses Datapump and GoldenGate tools?
- A. Direct Connection
- B. Physical Migration
- C. Logical Migration
- D. Indirect Connection
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.

- E. Limited productivity
- F. Simplified core-based licensing
正解：C、D
解説：
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.
質問 # 55
A customer is looking to migrate their old database backups from their on-premises data center to Oracle Cloud Infrastructure (OCI). Which OCI service is the most cost-effective?
- A. Block Volume
- B. Object Storage (standard)
- C. Archive Storage
- D. File Storage
正解：C
解説：
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.
