DEVOPS 1.So in the same way as part of your project Sonar cube is being replaced by a different static code analysis tool as a Jenkin administrator. Like where should you? Delete the sonar cube configuration and configure the new tool that will be implemented shortly. Answer: manage Jenkins and then go for global tool configuration 2.So which is being deployed by Java developers so and place the dot war file like dot war file in the Nexus repository. So there is an reposit Nexus repository name called Nexus. War file has to be placed in that. as a DevOps engineer will be using Jenkin to build the Java applications. In our current projects, we'll be using a like Jenkins to build the Java applications. So which is being developed by the Java developers and to place the.war file in the Nexus repository? Which build tool must be installed on the Jenkins server? Answer: MAVEN 3.So which of the following statement or incorrect? A. a Jenkin file can only be written in declarative pipeline syntax. B. scripted pipeline is a more recent feature of Jenkin pipeline C. in scripted pipelines in text node locked to the core work throughout the entire pipeline Answer: A & B 4. After inspecting the output of the previous jobs, if the previous job or other work is successful, the 11 team L1 team begins the subsequent job. So what Jenkin option you should select under built additional projects under post build actions. Answer: Trigger only if the build is stable 5. Git has been introduced like it has been added into your project as in version control system. So to make it easier for the developers to change and test the code to the production code. So as a Jenkin administrator, what option does on the project configuration page on the pipeline will be selected to tell Jenkin the URL of a specific Git lab code repository. So as a Jenkin administrator, which option on the project configuration page or the pipeline will you select to tell the URL of a specific GitLab code repository? o Answer: changing on the pipeline script from SCM of the configuration management on the pipeline script will change it. 6. Your company will automate all Jenkin jobs that are currently manually triggered in the coming week. All jobs triggers will take place at the same time as a manual triggers. The element team is currently manually starting five Jenkin jobs in your project at 6:00 AM every day. How will you use con expressions to automate these? Like those build jobs, how we will do it? Answer: 06*** 7. James has been tasked with developing engine can job that will check the code repository every minute to see if there has been any new commits. So every minute the code has to be checked if there is any new commits, so the job will be triggered. If your new commit occurs so whenever there is a new commit occurs like, the job will get automatically triggered. What is the appropriate con execution in this situation, and what option should be selected under build triggers? Answer: Cron Expression: ***** Build Triggers: Poll SCM (will ensure Jenkins polls the repository for new commits) 8. SonarQube will provide your project with a novel static code analysis technique. As a result, it is your responsibility to properly and mandatory connect the SonarQube server to the Jenkin tool so that Jenkin can detect the sonar QUBE and Sonar cube can perform the static code analysis. What prerequisites must be met before configuring Jenkin with the Sonar cube server via manage Jenkin secure like configuration system. So what precise must be met before configuring Jenkin with the SonarQube server by manage Jenkins configure system? Answer: Name, Server URL and Server authentication. 9. So Jenkins installation fails when attempting to install it on a raw server as part of a new project of your company. So while you're installing your Jenkin so it's getting failed on your server like. You have been tasked with quickly investigating and finding a solution, so you are asked to find a solution for it quickly. So after performing the necessary troubleshooting, you discovered that Java is not installed, so Java is not installed inside of your Jenkin. So that's the reason why it's not getting installed. So as a result you have Java installed on that server, but you have Java in that server already installed. So in order for this to work, you must also specify JDK as the Java installation path in Jenkins configuration. So you have a Jenkins configuration where you need to specify JDK inside of it. So what name should be entered into the ad JDK field of Jenkins global configuration tool? Answer: JAVA_HOME 10. In which programming language Jenkin tool can be designed?
