What are two characteristics of CI/CD?
- A. It introduces automation into all stages of app/database development.
- B. Development changes are automatically V tested on push/commits and merges.
- C. It requires Liquibase
- D. It prevents developers from merging their code changes back to the shared branch for security.
Answer: A,B
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.

NEW QUESTION # 32
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. Plan for a one-hour downtime and increase the number of OCPU while database is of-fline.
- B. 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.
- 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.
Answer: C
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 hardware innovations of the Exadata X8M allow customers to take advantage of Remote Direct Memory Access (RDMA). What resource does RDMA access?
- A. Compute Instances
- B. Persistent Memory
- C. Database Servers
- D. Storage Disks
Answer: B
Explanation:
Persistent memory is the resource that RDMA accesses in Exadata X8M. According to the Oracle website1, "Exadata X8M uses RDMA over Converged Ethernet (RoCE) to directly access the persistent memory in storage servers, bypassing the OS, IO, and network software stacks. This reduces IO latency by up to 10X compared to the previous generation of Exadata."
NEW QUESTION # 34
Which statement can be detected by monitoring of access to sensitive data?
- A. UPDATE quarter_reference set Q1='012022'
- B. CREATE index emp_id_idx on EMPLOYEES(emp_id);
- C. SELECT * from EMPLOYEES;
- D. SELECT SYSDATE from DUAL;
Answer: C
Explanation:
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 # 35
What three typical data types/models are covered by Oracle's Converged Database? (Choose all correct answers)
- A. Spatial
- B. Graph
- C. Images
- D. Terraform
- E. Relational
- F. Events
Answer: A,B,E
Explanation:
Graph, relational, and spatial are three typical data types/models that are covered by Oracle's Converged Database. A converged database is a multi-model, multitenant, multi-workload database that supports the data model and access method each development team wants, without unneeded functionality getting in the way. A graph data model represents data as nodes and edges, and enables complex queries based on relationships and patterns. A relational data model organizes data into tables with rows and columns, and supports SQL queries and transactions. A spatial data model stores and manipulates geometric and geographic data, such as points, lines, polygons, and raster images.
NEW QUESTION # 36

OCI Block Volumes is the service used by default by the MySQL Database Service to store user data to make it more resistant to failures. OCI Block Volumes provides high-performance block storage volumes that can be attached to MySQL DB systems running on OCI Compute instances. Block volumes are always encrypted at rest using AES-256 encryption keys. Block volumes also support backup and restore operations using snapshots or clones that can be used for disaster recovery or testing purposes.
NEW QUESTION # 42
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 m to your data center.
- B. 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.
- C. Exadata Cloud@Customer is hosted in 4 customer data center so the Exadata infrastructure is not registered in an region.
- D. Consider which availability domain (within the region) to create the Exadata Cloud#Customer infrastructure
Answer: A,B
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.
