NEW QUESTION # 15
Which three can be selected when using the console to create an autonomous database on an Autonomous Exadata Cloud@Customer?
- A. amount of database storage required
- B. amount of database OCPUs required
- C. client network
- D. size of the shared global area (SGA) to use
- E. workload type
Answer: A,B,E
Explanation:
These are three options that can be selected when using the console to create an autonomous database on an Autonomous Exadata Cloud@Customer. According to the Oracle documentation1, "When you create an Autonomous Database on Autonomous Exadata Cloud@Customer, you specify the following information: Database name, Database display name, Workload type, Admin password, License type, Number of OCPUs, Storage (TB), and Tags (optional)." The workload type can be either transaction processing or data warehouse.
NEW QUESTION # 16
Which are two characteristics of Autonomous Transaction Processing (ATP)? (Choose all correct answers)
- A. Statistics are gathered as part of bulk load operations
- B. Optimized for response time
- C. Stores data in columnar format
- D. Focuses on creation of indexes
- E. Creates autonomous data summaries
Answer: B,D
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 # 17
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 Au-tonomous Database.
- C. APEX can simply be installed by downloading the executable from OTN.
- D. An Autonomous Database with the workload type Data Warehouse, Transaction Pro-cessing, JSON or APEX.
- E. A DBA must create APEX admin and APEX users first before starting APEX from Oracle Cloud Infrastructure Console.
Answer: D
Explanation:
An Autonomous Database with the workload type Data Warehouse, Transaction Processing, JSON or APEX is a prerequisite of running APEX on an Autonomous Database. According to the Oracle documentation, "Oracle Application Express (APEX) is a low-code development platform that enables you to build scalable, secure apps with world-class features that can be deployed anywhere. APEX is preconfigured and fully managed in Oracle Autonomous Database (ADB). You can use APEX on any Autonomous Database workload type: Data Warehouse (ADW), Transaction Processing (ATP), JSON (AJD), or APEX (APEX)."

- A. Load Balancing (one load balancer)
- B. Connect (1Gbps public peering)
- C. Block Volume (up to 100 GB total storage)
- D. Autonomous Database (up to two database instances)
Answer: B
Explanation:
Connect (1Gbps public peering) is not an Always Free resource available for provisioning in your tenancy.

Answer: C
Explanation:
Customers are responsible for managing databases and customer VMs when they are using the Exadata Cloud Service. According to the Oracle documentation7, "Customers have full control over their databases running on Exadata Cloud Service, including root access for database servers." Additionally, according to the Oracle documentation8, "Customers can create customer VMs on Exadata Cloud Service database servers for their own use."
NEW QUESTION # 21
Multicloud strategy eliminates the reliance of a single cloud provider but also provides which two advantages? (Choose all correct answers)
- A. Compliance for use of specific geographies for data sovereignty laws
- B. Duplication of data and applications
- C. Ability to have private clouds and maintain customer data centers
- D. Workload utilization of specific services
Answer: A,D
Explanation:
Compliance for use of specific geographies for data sovereignty laws and workload utilization of specific services are two advantages of a multicloud strategy. A multicloud strategy allows organizations to use cloud services from more than one public cloud provider to run their applications. By doing so, they can achieve various benefits such as:
Compliance for use of specific geographies for data sovereignty laws: Some countries or regions may have regulations that require data to be stored or processed within their borders or jurisdictions. A multicloud strategy can help organizations comply with these laws by choosing cloud providers that have local presence or availability zones in the desired locations.
Workload utilization of specific services: Different cloud providers may offer different types of services or features that suit different workloads or requirements better than others. A multicloud strategy can help organizations leverage the best-of-breed solutions from each provider for their specific needs, such as performance, scalability, security, or cost-effectiveness.

NEW QUESTION # 27
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. 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. Open the database in OCI Console and increase the number of OCPU. No downtime required.
Answer: D
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.

Which two methods can you use to create or modify Oracle Cloud Infrastructure (OCI) re-sources? (Choose all correct answers)
- A. OCI REST APIs
- B. Remote Desktop Protocol (RDP)
- C. Secure Shell (SSH)
- D. OCI Command-line Interface (CLI)
- E. Serial console connection (SCC)
Answer: A,D
Explanation:
OCI REST APIs and OCI Command-line Interface (CLI) are two methods that you can use to create or modify Oracle Cloud Infrastructure resources. According to the Oracle documentation, "The Oracle Cloud Infrastructure APIs are typical REST APIs that use HTTPS requests and responses. You can use these APIs to interact with your cloud resources programmatically." Additionally, according to the Oracle documentation, "The OCI CLI is a tool that enables you to interact with Oracle Cloud Infrastructure services from the command line."
NEW QUESTION # 29
What are two characteristics of CI/CD?
- A. It requires Liquibase
- B. It prevents developers from merging their code changes back to the shared branch for security.
- C. It introduces automation into all stages of app/database development.
- D. Development changes are automatically V tested on push/commits and merges.
Answer: C,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.
