NEW QUESTION # 27
Which is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service?
Answer: B
Explanation:
The use case that is NOT a valid use case for leveraging the Oracle Cloud Infrastructure (OCI) Events service is " Capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances. " The OCI Events service is designed to provide event-driven architecture and enable automated responses to events occurring within the Oracle Cloud Infrastructure. It allows you to react to changes and activities happening within your OCI resources. The Events service can be used to trigger actions based on events like file uploads, resource changes, or task completions. However, capturing the OCI Monitoring service alarms and invoking autoscaling of compute instances is not a direct functionality provided by the OCI Events service. Autoscaling based on monitoring metrics is typically handled by the OCI Autoscaling service, which is specifically designed for that purpose. The OCI Monitoring service provides monitoring and alerting capabilities, while the Autoscaling service handles the dynamic scaling of compute instances based on predefined policies and thresholds.
NEW QUESTION # 28
Which testing strategy achieves high velocity of deployments and releases of cloud native applications?
(Choose the best answer.)
Answer: A
Explanation:
The testing strategy that achieves high velocity of deployments and releases of cloud native applications is " Automated testing. " Automated testing involves the use of automated tools and frameworks to execute tests, validate functionality, and detect issues or bugs in an application. By automating the testing process, developers and DevOps teams can rapidly test and validate code changes, ensuring that new features and updates are functioning correctly before being deployed to production. This approach helps increase the speed and efficiency of the testing process, allowing for faster and more frequent deployments of cloud native applications.
NEW QUESTION # 29
Which statement is NOT valid regarding the structure and behavior of Docker images and containers?
Answer: C
Explanation:
Docker images and containers have separate lifecycles. Oracle describes a Docker image as a read-only template used to create containers, while image implementations consist of immutable read-only layers. A running container adds its own writable runtime state without changing those underlying image layers.
Removing a container with docker rm removes that container instance; deleting the corresponding image requires a separate image-removal operation such as docker rmi. Oracle ' s Cloud Shell documentation likewise explicitly uses docker rmi when deleting local images. Therefore, deleting a container doesnotautomatically or permanently delete its source image. Statements A, B, and D describe the layered and copy-on-write behavior associated with Docker containers, making C the invalid statement.
NEW QUESTION # 30
Which container network interface plugin must be selected when creating an Oracle Cloud Infrastructure Container Engine for Kubernetes cluster that requires pod IP addresses to be directly routable from peered virtual cloud networks and on-premises environments?
Answer: B
Explanation:
The OCI VCN-Native Pod Networking CNI plugin assigns pod IP addresses directly from the OCI VCN address space instead of allocating addresses from a separate overlay network. Oracle specifically states that these pod IP addresses are directly routable from other VCNs connected through VCN peering and from on- premises networks. This architecture makes pods first-class participants in OCI networking and enables native VCN functionality such as network security groups, security lists, and VCN flow logs to be applied to pod traffic. Flannel uses an overlay model and therefore does not provide the required directly routable VCN pod addresses. Calico is commonly associated with Kubernetes NetworkPolicy enforcement rather than being the required OCI native routing CNI. Therefore, D is correct.
NEW QUESTION # 31
You are building a secure containerized application on Container Engine for Kubernetes (OKE) that must access OCI resources securely using OKE Workload Identity. Which cluster type must you select during creation to enable support for OKE Workload Identity?
Answer: A
Explanation:
OKE Workload Identity is anenhanced-cluster capability. Oracle ' s current Kubernetes Engine documentation explicitly lists workload identity as supported by Enhanced clusters and not supported by Basic clusters.
Workload Identity enables IAM policies to authorize individual Kubernetes workloads according to attributes such as cluster, namespace, and service account, avoiding broader permissions inherited from worker-node instance principals. Basic clusters support standard Kubernetes and OKE functionality but exclude enhanced capabilities including Workload Identity, virtual nodes, self-managed nodes, and advanced cluster add-on management. "Dedicated cluster" and "Autonomous cluster" are not the OKE cluster types used for this feature classification. Therefore, an application architecture requiring OKE Workload Identity must use an Enhanced cluster, making option A correct.
