NEW QUESTION # 38
What does ORDS stand for?
- A. Oracle Resilient Data Security
- B. Oracle REAP Diagnosis Systems
- C. Oracle REST Data Services
- D. Oracle Rapid Data Systems
Answer: C
Explanation:
ORDS stands for Oracle REST Data Services, which is a Java application that enables developers to access and manipulate data in Oracle Database using RESTful web services. According to the Oracle documentation2, "Oracle REST Data Services (ORDS) bridges HTTPS and your Oracle Database. A mid-tier Java application, ORDS provides a Database Management REST API, SQL Developer Web, a PL/SQL Gateway, SODA for REST, and the ability to publish RESTful Web Services for interacting with the data and stored procedures in your Oracle Database."
NEW QUESTION # 39
Which are two characteristics of Autonomous Transaction Processing (ATP)? (Choose all correct answers)
- A. Creates autonomous data summaries
- B. Statistics are gathered as part of bulk load operations
- C. Stores data in columnar format
- D. Optimized for response time
- E. Focuses on creation of indexes
Answer: D,E
Explanation:
Focuses on creation of indexes and optimized for response time are two characteristics of Autonomous Transaction Processing (ATP). According to the Oracle documentation, "Autonomous Transaction Processing is a database service that is optimized for transaction processing or mixed workloads. It delivers the best experience for mission-critical applications that require high performance, high concurrency, and low latency. Autonomous Transaction Processing automatically creates indexes, materialized views, and partitions based on the workload." Additionally, according to the Oracle documentation, "Autonomous Transaction Processing is optimized for response time. It uses a combination of caching, in-memory columnar format, and result set caching to deliver fast response times."
NEW QUESTION # 40
The DBA has determined that number of OCPU assigned to an Autonomous Database does not provide sufficient performance. Which option does the DBA have in this case?
- A. Call Oracle Cloud Support and raise a request to increase number of OCPU. Expect a downtime of approximately one hour.
- B. Open the database in OCI Console and increase the number of OCPU. No downtime required.
- C. Plan for a one-hour downtime and increase the number of OCPU while database is of-fline.
- D. 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.
Answer: B
Explanation:
This option is the correct way to increase the number of OCPU assigned to an Autonomous Database. According to the Oracle documentation2, "You can scale your Autonomous Database on demand by adding CPU cores or storage. You can also enable auto scaling to allow your Autonomous Database to automatically use up to three times more CPU and IO resources than its allocated CPU core count." The scaling operation does not require any downtime or affect the availability of the database.
NEW QUESTION # 41
What is NOT a workload that can be selected when provisioning an Autonomous Database?

This statement can be detected by monitoring of access to sensitive data, because it queries all the data from the EMPLOYEES table, which may contain personal or confidential information about the employees, such as name, address, salary, or performance. Monitoring access to sensitive data can help protect the data from unauthorized or malicious use, and ensure compliance with data privacy regulations.
NEW QUESTION # 55
Which two statements are true when deciding which Oracle Cloud Infrastructure (OCI) region to register an Exadata Cloud@Customer infrastructure in?
- A. Consider which availability domain (within the region) to create the Exadata Cloud#Customer infrastructure
- B. Consider the physical proximity of the region you register the infrastructure m to your data center.
- C. Exadata Cloud@Customer is hosted in 4 customer data center so the Exadata infrastructure is not registered in an region.
- D. Consider any business polices or regulations that preclude the use of a particular report The Exadata Cloud@Customer region can be changed after the infrastructure is created.
Answer: B,D
Explanation:
These are two statements that are true when deciding which Oracle Cloud Infrastructure (OCI) region to register an Exadata Cloud@Customer infrastructure in. According to the Oracle documentation5, "When you register an Exadata Cloud@Customer infrastructure in an OCI region, consider any business policies or regulations that preclude the use of a particular region." This means that you should be aware of any legal or compliance requirements that might limit your choice of OCI regions for Exadata Cloud@Customer. According to the Oracle documentation6, "Consider the physical proximity of the region you register the infrastructure in to your data center. The closer they are physically located, the lower the network latency between them." This means that you should also consider the network performance and availability when choosing an OCI region for Exadata Cloud@Customer.
NEW QUESTION # 56
What are two characteristics of CI/CD?
- A. It prevents developers from merging their code changes back to the shared branch for security.
- B. Development changes are automatically V tested on push/commits and merges.
- C. It requires Liquibase
- D. It introduces automation into all stages of app/database development.
Answer: B,D
Explanation:
These are two characteristics of CI/CD, which is a set of practices that automate the building, testing, and deployment stages of software development. According to the Red Hat website9, "CI/CD introduces ongoing automation and continuous monitoring throughout the lifecycle of apps, from integration and testing phases to delivery and deployment." This means that CI/CD aims to reduce manual tasks and increase efficiency and reliability across the development life cycle. According to the IBM blog10, "Continuous integration (CI) is an automation process for developers. Successful CI means new code changes to an app are regularly built, tested, and merged to a shared repository." This means that CI/CD enables developers to integrate their code changes frequently and automatically, ensuring code quality and consistency.
