QuestionQ1

DevOps Automation

How do OCI DevOps Deployment Pipelines lower the risk and complexity of production applications?

  • A By reducing change-driven errors introduced by manual deployments
  • B By scaling builds with service-managed build runners
  • C By working with existing Git repositories and CI systems
  • D By eliminating downtime of production applications
Explanation

OCI DevOps deployment pipelines automate and standardize releases, reducing change-driven errors that manual deployments can introduce.

QuestionQ2

Observability and Operations

As a cloud engineer, you manage a Kubernetes cluster on the Oracle Cloud Infrastructure (OCI) platform for your organization. You want to ensure dependable Kubernetes operations at scale while minimizing the operational overhead of managing worker node infrastructure.

Which cluster option best meets this requirement?

  • A Using OCI OKE managed nodes with cluster autoscalers to eliminate worker node infrastructure management
  • B Using OCI OKE virtual nodes to eliminate worker node infrastructure management
  • C Using Kubernetes cluster add-ons to automate worker node management
  • D Creating and managing worker nodes using OCI compute instances
Explanation

OCI OKE virtual nodes are fully managed by Oracle and provide a serverless Kubernetes experience. They support running containerized workloads at scale without the operational overhead of managing, scaling, upgrading, or troubleshooting worker-node infrastructure.

QuestionQ3

DevOps Automation

How does the Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) Cluster Autoscaler decide when to create new nodes for an OKE cluster?

  • A When the CPU or memory utilization crosses a configured threshold.
  • B When the resource requests from pods exceed a configured threshold.
  • C When the custom metrics from the services exceed a configured threshold.
  • D When the rate of requests to the application crosses a configured threshold.
Explanation

OKE’s Kubernetes Cluster Autoscaler scales node pools according to pod resource requests. It adds nodes when a pod cannot be scheduled because the existing cluster has insufficient requested resources available; it does not use node CPU or memory utilization, custom service metrics, or application request rate as its node-creation trigger.

QuestionQ4

Oracle DevOps Practices

A team plans to deploy artificial intelligence and machine learning workloads in its OCI Container Engine for Kubernetes (OKE) cluster. It prioritizes strong isolation, cost efficiency, and the ability to use serverless capabilities.

Which solution is most suitable for these requirements?

  • A Virtual nodes in OKE
  • B Self-Managed Nodes in OKE
  • C Managed nodes in OKE
  • D Container Instances in OCI
Explanation

OKE virtual nodes deliver a serverless Kubernetes experience, provide hypervisor-level isolation for pods, and charge for the precise compute resources consumed by each pod rather than for underutilized whole servers. This combination supports isolated AI and ML workloads with efficient consumption-based costs.

QuestionQ5

Infrastructure as Code

Which command creates the Docker registry secret required by the application manifests so that OKE can pull images from Oracle Cloud Infrastructure Registry?

  • A
  • B
  • C
  • D
Explanation

An OKE image-pull secret for Oracle Cloud Infrastructure Registry is created with kubectl create secret docker-registry. It must use the OCIR regional endpoint (<region-key>.ocir.io) and authenticate with a username in the form <tenancy-namespace>/<oci-username>, along with an OCI auth token and email address.
