The Kubernetes Master node serves as the central control plane for managing the cluster’s resources
and orchestrating workload deployment.
What are the primary responsibilities of the Kubernetes Master node?

• A. The Master node is primarily tasked with executing application workloads and ensuring their availability within the cluster.
• B. The Master node oversees the scheduling and allocation of cluster resources, ensuring optimal utilization across nodes.
• C. The Master node monitors network traffic within the cluster, ensuring secure communication and efficient data transfer between nodes.
• D. The Master node serves as a repository for storing container images, facilitating rapid deployment and scaling of applications.

As a DevOps Engineer, you are tasked with explaining the key concepts of Terraform to a new team
member. You want to ensure they understand the fundamental concepts of Terraform.
Which of the following best describes the purpose of Terraform variables?

• A. Terraform variables are used to manage the life cycle of Terraform resources.
• B. Terraform variables are used to define input values for Terraform configurations, allowing for customization and reuse of infrastructure code.
• C. Terraform variables are used to output the final state of the infrastructure after deployment.
• D. Terraform variables are used to define the structure and organization of Terraform configuration files.

As a DevOps engineer at XYZ Corp, you are responsible for ensuring the smooth operation of high-
traffic web applications hosted on Oracle Cloud Infrastructure (OCI). The web applications run on
multiple OCI resources, including virtual machines, load balancers, and databases. Recently, users
have reported failures while accessing one of the OCI-based web applications, and you suspect HTTP
5XX errors on the load balancer. You need to quickly identify and address this issue.
Which of the following statements can assist you in quickly identifying and monitoring the HTTP 5XX
error rate on the load balancer and setting up notifications?

• A. Use Custom Metrics of the Monitoring service to collect HTTP 5XX error rates from the load balancer and set up Service Connectors with third-party services such as PagerDuty or Slack.
• B. Use Metrics and Alarms of the Monitoring service with Container Engine for Kubernetes (OKE) to monitor HTTP 5XX errors on Kubernetes resources and correlate them with other OCI resources.
• C. Use Event Rules to detect HTTP 5XX errors on the load balancer and trigger automated actions using OCI Functions or API Gateway.
• D. Use Metrics and Alarms of the Monitoring service to monitor the HTTP 5XX error rate on the load balancer and set up notifications with OCI Notifications.

Your team is responsible for deploying a new version of an application that is being used by your
company’s finance department. The application is critical to the department’s operations, and any
downtime could have serious consequences.
What is the recommended approach in OCI for creating environments for this scenario?

• A. Deploy the application to two separate OCI tenancies to ensure complete isolation between environments.
• B. Use a single Kubernetes cluster with two node pools, one for the blue-green environment and one for the canary environment.
• C. Configure two OKE clusters, selecting the blue-green traffic shift strategy using a load balancer.
• D. Use a single OCI region and create two separate Virtual Cloud Networks (VCNs), one for the blue environment and one for the green environment.

Your team is working on a project to deploy a microservices-based application on a cloud platform
using Terraform. Each microservice has specific configurations and dependencies, and you want to
ensure modularity, reusability, and consistency across deployments.
Which Terraform feature would you use to achieve these objectives efficiently?

• A. Terraform Providers
• B. Terraform Workspaces
• C. Terraform Variables
• D. Terraform Modules

As a developer working on a software project to be deployed on OKE, you have created a Helm chart
for your application. You want to deploy the chart using OCI DevOps service.
Which statement is true about deploying a Helm Chart using OCI DevOps service?

• A. A single chart can be installed only once into the same cluster, and create single release.
• B. The Helm charts must be located in the OCI Container Registry repository for deployment.
• C. The values.yaml file is a generic file located in the OCI Container Registry. You must create a reference to this file.
• D. Oracle Cloud Infrastructure (OCI) DevOps service supports deployment of Helm charts to Container Instances.

You are a developer and have been asked to develop an e-commerce website for your organization. It
must support a variety of clients including desktop browsers, mobile browsers and native mobile
applications.
Which two approaches can you use to build the application to achieve deployment independence,
easier technology upgrades, and resiliency to architecture changes? (Choose two.)

• A. Use monolithic approach, as it allows you to easily redeploy your applications to perform frequent updates.
• B. Implement each module as an independent service/process which can be replaced, updated, or deleted without disrupting the rest of the application.
• C. Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.
• D. Choose monolithic approach over microservices as it has better fault isolation capability.
• E. Use microservices architecture as it eliminates any long-term commitment to a technology stack.

A software development team is working on a prototype using Node.js and MongoDB as their
programming language and database, respectively. They need to develop and test isolated web
applications or RESTful APIs. They are looking for a simple, quick, and secure way to run containers
without managing any servers.
Which OCI service is best suited for this use case?

• A. OCI Functions
• B. Container Instances
• C. OCI DevOps Project
• D. Compute Instances

Observability helps understand system behavior, but it has limitations.
Which of the following tasks cannot be accomplished solely through observability?

• A. Optimizing resource utilization
• B. Automating software deployments
• C. Identifying infrastructure bottlenecks
• D. Identifying resource consumption

As a DevOps engineer working with OCI DevOps, you are managing artifacts for a microservices
application.
Based on your understanding of working with DevOps projects and artifacts, which statement is true?

• A. Artifacts can be used directly by OCI DevOps without the need for them to be located or mirrored in an OCI Artifact or Container registry.
• B. In the build pipeline, to store the Managed Build stage outputArtifacts. you need an OCI Object storage.
• C. It is recommended to make artifacts immutable to prevent any modifications after they are uploaded.
• D. Once created, the artifact's name. type, and source cannot be modified.
