A DevOps engineer is asked to access an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster to deploy new applications and manage existing ones.
Which two statements are true? (Choose two.)

• A. The only available option when a cluster's Kubernetes API endpoint has a public IP address is to control the cluster locally using kubectl and the Kubernetes Dashboard.
• B. Generating an API signing key pair is not required while setting up cluster access using local machine if the public key is not already uploaded in the console.
• C. To access the cluster using kubectl, you have to set up a Kubernetes manifest file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.manifest directory.
• D. To access the cluster using kubectl, you have to set up a Kubernetes configuration file for the cluster. The kubeconfig file by default is named config and stored in the $HOME/.kube directory.
• E. When a cluster's Kubernetes API endpoint has a public IP address, you can access the cluster in Cloud Shell by setting up a kubeconfig file.

You're using Oracle Cloud Infrastructure (OCI) DevOps service to automate your software releases to release features more frequently and with fewer errors. While deploying an update to production, one of your deployment stages failed.
What action should you perform in your Deployment Pipeline?

• A. Use OCI DevOps Trigger and Rerun tool to avoid downtime.
• B. Automate back up and use the rerelease stage in the Deployment Pipeline.
• C. Add Rescue and Trigger stages to automatically trigger the failed deployment.
• D. Roll back the failed stage in the pipeline to the previous successful released version

As an engineer building and deploying applications using an OCI DevOps project, which two capabilities can help ensure the security and reliability of the code in the build and deployment pipelines? (Choose two.)

• A. Using third-party tools like Ansible, Terraform, or OverOps to analyze code for security defects or bugs in code quality
• B. Using third-party tools like Sonatype, SonarQube, or OverOps to analyze code for security defects or bugs in code quality
• C. Using version control tools like Git or SVN to track and manage changes in the codebase
• D. Using JIRA to track user stories and bug fixes in the development process
• E. Using Application Dependency Management (ADM) to identify security weaknesses in software applications by checking their dependencies

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