NEW QUESTION # 45
What is the difference between continous deployment and continous delivery with regard to DevOps lifecycle
? (Choose the best answer.)
- A. Continuous delivery initates deployment automatically while continuous deployment works on manual deployment.
- B. There is no difference between continuous deployment and continuous delivery
- C. Continuous delivery initates deployment manually while continuous deployment works on automating
- D. Continuous delivery involves tasks for managers while continuous deployment is for developers.
Answer: C
Explanation:
Explanation
The difference between continuous deployment and continuous delivery in the DevOps lifecycle is that continuous delivery involves initiating deployments manually, while continuous deployment focuses on automating the deployment process. Explanation: Continuous delivery and continuous deployment are both practices in the DevOps lifecycle that aim to streamline the software release process. However, there is a distinction between the two based on the level of automation involved in the deployment phase. Continuous delivery refers to the ability to deliver software changes to production in a reliable and efficient manner. It involves having a well-defined deployment process and a reliable pipeline that can be triggered manually to deploy the software changes. With continuous delivery, the deployment process can be initiated by a human decision, allowing for a final re-view or approval before releasing the software. On the other hand, continuous deployment takes the automation aspect further by automatically deploying software changes to production as soon as they pass through the entire delivery pipeline. In continuous deployment, the deployment process is fully automated, and there is no human intervention required to initiate the deployment. Once the changes are tested and validated, they are automatically deployed to the production environment. In summary, continuous delivery involves manual initiation of the deployment process, while continuous deployment focuses on automating the deployment process without the need for human intervention.

- E. 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.
Answer: A,B,E
Explanation:
Explanation
The three statements that are true regarding setting up cluster access for an Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) cluster are: 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. This allows you to authenticate and interact with the cluster using kubectl. Generating an API sign-ing key pair is a mandatory step when setting up cluster access using a local machine if the public key is not already uploaded in the console. This key pair is used for authentication and securing the connection to the cluster. To access the cluster using kubectl, you need to set up a Kubernetes con-figuration file (kubeconfig) for the cluster. By default, the kubeconfig file is named "config" and is stored in the $HOME/.kube directory. This file contains the necessary information and credentials to authenticate and communicate with the cluster. These steps enable the DevOps engineer to access and manage the OKE cluster, deploy new applications, and manage existing ones using kubectl or other Kubernetes management tools. Reference:

Answer: D
Explanation:
Explanation
The next step to ensure a secure and reliable deployment after completing code analysis, image scanning, and automated testing is to add a control stage approval within the deployment pipeline. A control stage approval is a stage in the OCI DevOps Deployment Pipeline that allows you to pause the pipeline execution and require manual approval before proceeding to the next stage. You can use a control stage approval to perform additional checks, such as reviewing the test results, verifying the deployment environment, or validating the compliance requirements. By adding a control stage approval, you can reduce the risk of deploying faulty or unauthorized code to production.
