NEW QUESTION # 24
When it comes lo Fault Domains (FDs) in Oracle Cloud Infrastructure (OCI). what is the primary purpose of distributing compute instances across different FDs within an availability domain?
- A. To achieve high availability and protect against unexpected hardware failures
- B. To ensure that all instances experience hardware maintenance events simultaneously
- C. To optimize resource usage and consolidate instances on the same hardware
- D. To centralize instances for easier management and monitoring
Answer: A
Explanation:
The primary purpose of distributing compute instances across different Fault Domains within an availability domain is to protect against unexpected hardware failures and ensure high availability. Fault Domains provide a way to distribute instances such that they are not on the same physical hardware, reducing the risk of simultaneous failures affecting all instances.
NEW QUESTION # 25
Which statement best describes the default AuthZ behavior for users and groups in Oracle Cloud Infrastructure IAM?
- A. Access to resources in explicitly granted in policies; otherwise, it is denied by default.
- B. Users and groups must request access from the administrator for each resource.
- C. Users and groups are automatically granted access to all resources.
- D. Users and groups arc granted access based on their roles without the need for policies.
Answer: A
Explanation:
In Oracle Cloud Infrastructure (OCI) IAM, the principle of least privilege is applied, which means that access to resources is denied by default. Users and groups are granted access explicitly through policies that define the actions allowed on specific resources, ensuring that access is controlled and minimized to what is necessary.

Which feature of the OCX Resource Manager service would you use to differentiate between the real-world state of your infrastructure and the slack's last-executed configuration?
- A. Dill Detection
- B. View State
- C. Apply or Import State
- D. Drift Detection
Answer: D
Explanation:
Drift Detection is a feature in OCI Resource Manager that helps users identify discrepancies between the real-world state of their infrastructure and the configuration defined in their Terraform state file. This feature is crucial for maintaining the integrity of infrastructure deployments, as it highlights unintended changes or drifts that might have occurred outside of Terraform's management.

- A. HAVING
- B. WHERE
- C. IF
- D. GROUP
Answer: B
Explanation:
The SQL WHERE keyword is used to specify a condition while fetching data from a single table or by joining with multiple tables. If the given condition is satisfied, then it returns the specific value from the table.
NEW QUESTION # 31
How do you construct I he collection relation cache foe a course if it is not available?
- A. Create the cache entry manually.
C Execute the "syne-rel-cache-all''command in sync to generate the events for relation- cache-updater andre-create the cache. - B. Restart the relation-cache-updater job.
- C. Drain the relation-cache-updater input Kalka topic.
Answer: C
Explanation:
In microservices and distributed systems, caches are often used to improve performance. The command
'sync-rel-cache-all' suggests a process to synchronize and regenerate the cache for collection relationships, which is a plausible approach to constructing or reconstructing a cache in such systems.
NEW QUESTION # 32
Which is a key feature of Oracle Cloud Infrastructure (OCI) Container Registry?
- A. It is not Open Container Initiative-compliant, limiting the types of container images it can store.
- B. It provides a managed registry for container images, ideal for storing and sharing virtual machine images.
- C. It supports private access from Oracle Cloud Infrastructure resources using an Internet gateway.
- D. It enables you to store container images that conform to Open Container Initiative specifications, manifest lists for multiple architectures, and Helm charts.
Answer: D
Explanation:
Oracle Cloud Infrastructure Container Registry is a managed Docker registry service that supports storing, sharing, and managing development artifacts like Docker images. It is compliant with the Open Container Initiative (OCI) specifications, supporting a wide range of container images and configurations, including manifest lists for multiple architectures and Helm charts, making it ideal for modern containerized applications.
NEW QUESTION # 33
What is the relationship between Oracle Cloud Infrastructure regions and availability domains?
- A. A region encompasses multiple realms, each with its own availability domains.
- B. Availability domains provide low-latency connectivity to the Internet within a region.
- C. Availability domains are isolated from regions and can exist independently.
- D. Regions consist of multiple availability domain, and resources are typically specific to one availability domain.
Answer: D
Explanation:
Oracle Cloud Infrastructure regions consist of one or more availability domains. Each availability domain is a standalone, isolated data center within a region, and resources provisioned in an availability domain are specific to that domain, providing fault tolerance and high availability within a region.

NEW QUESTION # 35
Which statement best describes the primary use of the Sunbird client service library (CSL) in an application?
- A. It uses CSL for rendering various forms within the application's user interface.
- B. It employs CSL to execute complex business logic and interact with external APIs.
- C. It leverages CSL to provide a set of common user interface components across the application.
- D. None of these options accurately represents the purpose of CSL within the application.
Answer: B
Explanation:
Client Service Libraries (CSL) are typically used to encapsulate the interactions with backend services, providing a simplified API for front-end applications. They can execute business logic and interact with external APIs, abstracting the complexity of direct service communications.
NEW QUESTION # 36
You have configured an Oracle Cloud Infrastructure (OCI) Load Balancer to distribute traffic to two compute instances in a private subnet. However, one of the target instance's health is marked as Critical. Which is NOT a typical reason for this?
- A. The target instance did not respond with a successful HTTP status code.
- B. The target instance is in a different availability domain than the Load Balancer.
- C. The network security group rules of the target instance do not allow traffic on the necessary ports.
Answer: B
Explanation:
The health of an instance in the context of OCI Load Balancer does not directly depend on its availability domain. Instances can be in different availability domains from the Load Balancer and still receive traffic as long as they are within the same region and the network configuration allows it. Typical reasons for an instance to be marked as Critical include failing health checks due to issues like improper security group configurations or the instance not responding correctly, but not because of its placement in a different availability domain.
NEW QUESTION # 37
What is the primary purpose of Oracle Cloud Infrastructure Resource Manager (ORM)?
- A. To provision and manage Oracle Cloud Infrastructure resources through the "infrastructure-as-code" model using Terraform
- B. To provide a managed repository for source code
- C. To create and manage container images
- D. To automate software builds and deployments
Answer: A
Explanation:
Oracle Cloud Infrastructure Resource Manager (ORM) is a managed service that enables the provisioning and managing of OCI resources through the infrastructure-as-code model. It uses Terraform by HashiCorp, allowing users to define and apply configurations using declarative code, thereby automating the setup and maintenance of cloud resources efficiently.
NEW QUESTION # 38
Which Oracle Cloud Infrastructure (OCI) IAM policy statement should be defined to ensure that members of the NetworkAdmins group can create and configure Virtual Cloud Network components in the Project-A compartment?
- A. Allow group NetworkAdmins to read virtual- network- family in compartment Project-A.
- B. Allow group NetworkAdmins to create virtual-network-family in compartment Project-A.
- C. Allow group NetworkAdmins to manage virtual-network-family in compartment Project-A.
Answer: C
Explanation:
To allow members of the NetworkAdmins group to create and configure Virtual Cloud Network (VCN) components within the Project-A compartment, the policy statement should provide 'manage' privileges to the
'virtual-network-family' in that compartment. This allows the group to perform all actions within the virtual network resource family, including creation and configuration.
