Your organization has deployed their e-commerce application on Oracle Container Engine for Kubernetes (OKE) and they are using the Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the ' custom create ' option, and their Virtual Cloud Network (VCN) has three public subnets with associated Route Tables, Security Lists, and Internet Gateway.
However, their application containers are failing to deploy. On investigation, they discover that the images are not being pulled from the designated OCIR repository, even though the YAML configuration has the correct path to the images. What is a valid concern here that needs to be further investigated?

• A. VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.
• B. Security List rule for TCP port 22 needs to be added to connect to the OCIR service.
• C. Identity and Access Management (IAM) credentials need to be added for each user that deploys applications to the OKE cluster.
• D. OKE cluster needs to have a secret with the credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.

Which configuration parameter defines the duration a message remains inside an Oracle Cloud Infrastructure (OCI) Queue before being automatically deleted by the service if it is not consumed?

• A. Visibility timeout
• B. Polling timeout
• C. Maximum retention period
• D. Maximum delivery attempts

You have developed a cloud-native application on OCI, and you need to enable diagnostic logging for an OCI API Gateway deployment and a backend Oracle Function. Corporate compliance mandates that both the gateway activity and the function execution logs must be collected and stored in separate centralized log resources under a common log group named AppLoggingGroup.
Which TWO configuration steps must you perform within the OCI Logging service to satisfy these requirements?

• A. Create a Custom Log resource for both the API Gateway and the Oracle Function, then configure dynamic groups to push their logging payloads.
• B. Create an OCI Logging Agent Configuration specifying the API Gateway and the Oracle Function OCIDs as target custom log inputs.
• C. Create an OCI Logging Service Log resource under AppLoggingGroup, selecting Compute as the service and the gateway ' s load balancer as the resource.
• D. Create an OCI Logging Service Log resource under AppLoggingGroup, selecting Functions as the service and the target application as the resource.
• E. Create an OCI Logging Service Log resource under AppLoggingGroup, selecting API Gateway as the service and the target deployment as the resource.

Which key pillar of cloud native development should be utilized when a development team needs to automate build, test, and release cycles to achieve rapid and reliable software delivery?

• A. Microservices Architecture
• B. DevOps Principles
• C. Serverless Computing
• D. Containerization

Which is the smalled unit of Kubernetes architecture?

• A. Pod
• B. Cluster
• C. Container
• D. Node
