Explanation

To use a Kubernetes cluster in your deployment architecture on Oracle Cloud Infrastructure (OCI) with OCI DevOps service, the two recommended tools or services are: Terraform: Terraform is a widely used Infrastructure-as-Code (IaC) tool that allows you to define and manage your infra-structure resources in a declarative way. You can use Terraform to define and provision your Ku-bernetes cluster on OCI, including the necessary networking, compute resources, and container services. Ansible Collection: Ansible is an open-source automation tool that helps with configuration management, application deployment, and orchestration. The Ansible Collection for OCI provides modules and playbooks specifically designed to manage and interact with OCI resources, including Kubernetes clusters. You can use Ansible Collection to automate the deployment and management of your Kubernetes cluster on OCI. The other options mentioned are not directly related to managing Kubernetes clusters on OCI: Compute Jenkins Plug-in: Jenkins is a popular open-source automation server used for Continuous Integration/Continuous Deployment (CI/CD) processes. The Compute Jenkins Plug-in is specific to managing OCI compute resources using Jenkins but does not directly address Kubernetes cluster deployment. Chef Knife Plug-in: Chef is a configuration management tool that helps with managing infrastructure as code. The Chef Knife Plug-in is used to interact with the Chef tool, but it does not directly address Kubernetes cluster deployment on OCI. OCI Resource Manager: OCI Resource Manager is a service that helps you automate the process of deploying infrastructure resources on OCI. While it can be used to manage various OCI resources, including compute instances, it does not specifically focus on Kubernetes cluster deployment.

Explanation

In the Deployment Pipeline, when a deployment stage fails during the deployment of an update to production, the recommended action is to: Rollback the failed stage in the pipeline to the previous successful released version. By rolling back the failed stage to the previous successful version, you can revert the deployment to a known stable state and prevent the failed changes from being re-leased to production. This helps to maintain the stability and integrity of the application. It allows you to address the issues encountered in the failed stage, make necessary fixes or adjustments, and then proceed with the deployment again once the issues are resolved. The other options mentioned are not the most appropriate actions to perform in this scenario: Automating backup and using the rerelease stage: While backups are important for data protection, automating backup and using a rerelease stage would not directly address the failure in the deployment stage. It is more focused on data backup and recovery. Adding Rescue and Trigger stages: Adding Rescue and Trigger stages might help in certain situations, but they are not the primary solution for handling a failed deployment stage. They are more related to error recovery mechanisms or additional deployment steps, rather than specifically addressing the failed stage. Using OCI DevOps Trigger and Rerun tool: While OCI DevOps Trigger and Rerun tool can be useful for automating and managing deployments, it is not specifically designed to handle a failed deployment stage. It is more focused on triggering and rerunning pipelines or stages based on specific conditions or events.

Explanation

The recommended solution to achieve the requirements mentioned would be: Configure OCI Com-pute agent on OCI compute instances to collect the required resource metrics. Use OCI Events and Functions services to track the end-to-end deployment pipeline (com.oraclecloud.devopsdeploy.createdeployment) and the creation of new OCI Object Storage buckets (com.oraclecloud.objectstorage.createbucket). Finally, utilize OCI Notifications and Events services to notify these changes. Explanation: Continuous monitoring with resource metrics: Install and configure the OCI Compute agent on the OCI compute instances to collect the required re-source metrics such as CPU utilization, memory utilization, and disk IOPS. This ensures continuous monitoring of the VMs as they are migrated to OCI. Monitoring the deployment pipeline: Utilize the OCI Events service to track the end-to-end deployment pipeline. Specifically, use the event type "com.oraclecloud.devopsdeploy.createdeployment" to monitor the deployment process. This allows you to track the progress and status of the migration workflow. Notification for new OCI Object Storage buckets: Leverage the OCI Notifications service in conjunction with the OCI Events ser-vice. Set up a notification rule to trigger an email notification whenever a new OCI Object Storage bucket is created. Use the event type "com.oraclecloud.objectstorage.createbucket" to identify the creation of new buckets. By combining the OCI Compute agent, OCI Events service, Functions service, and Notifications service, you can ensure continuous monitoring of resource metrics, track the deployment pipeline, and receive email notifications for any new OCI Object Storage bucket creations during the migration workflow.

Explanation

The company can use the OCI DevOps Triggers feature to automate deployment of their application code changes to the production server. Therefore, the correct answer is: OCI DevOps Triggers feature can be used to automate deployment. OCI DevOps Triggers allow for automatic builds and de-ployments based on changes to the code repository. When a new commit is pushed to the reposito-ry, the trigger can initiate a build pipeline that creates an artifact and deploys the new version of the application to the production server.
