Q42. Which arc true when installing new plugins? Choose 2 answers

If you check the “Enable rollbacks when upgrading” box, future updates to an the plugin can easily be rolled back when necessary.

The previous public release of a plugin is installed for reliability instead of Installing the most recent public release.

Most plugins can be Installed without stopping and starting Jenkins.

You must install all required and optional dependencies before Installing the plugin with the plugin manager.

If you are running Jenkins under an HTTP proxy, you must configure HTTP proxy access for the plugin manager before Installing or updating plugins.

Q43. A freestyle job is set up to “Enable concurrent builds if necessary” and configured to run on a single node. How can you ensure that multiple concurrent runs share the same workspace?

Pass the argument -Dhuason.model .Run. lockworkspace=false in the Jenkins master Invocation.

Check “Do not lock workspace” In the Advanced Project Options of the project.

Multiple concurrent runs can never share the same workspace.

Define a “Custom workspace” path for the job.

False

True

H/15 * * * *

15 * * * *

Q47. What’s an example of SCM software?

Jenkins

Subversion

Git

Both Git and Subversion

Q48. What’s not true about a build executor?

The default number of executors on a node is 4.

You can run many of them in parallel.

They can run on the master.

It runs projects dictated by Jenkins.

Q49. Which of the following statements are TRUEabout Jenkins Pipeline?
Choose 2 answers

A Pipeline job must contain at least three stages.

It is not possible to call a Freestyle Job from within a Pipeline Job.

The Pipeline syntax supports running steps in parallel on different agents.

When using a Multibranch Pipeline, Jenkins can automatically create Jobs for each branch in the source code repository.

Pipeline jobs survive master restarts only If the Pipeline definition script Is checked into an SCM.

Q50. Which answer best describes continuous deployment?

Building in 60 minutes or less.

A software development discipline where software is built so that it can be released to production at any time.

A software development practice where contributors are integrating their work very frequently.

A software development discipline where software is released continuously as part of an automated pipeline.

Q51. You are a DevOps engineer in charge of your team’s Jenkins server. Your project is on major version “1”. You want to ensure that this variable, MAJOR_VERSION, is available throughout your pipeline that is defined in a Jenkinsfile. Which of the following ways could you accomplish that using the “environment” directive?

environment(MAJOR_VERSION = 1)

environment { steps { sh ” export MAJOR_VERSION=1″ }}

environment { MAJOR_VERSION = 1 }

environment [MAJOR_VERSION=1]

Q52. What’s the difference between authentication and authorization?

None of these

Authorization is more strict

Authorization identifies a user, while authentication dictates what a user is allowed to do.

Authentication identifies a user, while authorization dictates what a user is allowed to do.

Q53. Which of the following are true about credentials that are implemented in a Declarative Pipeline using the “credentials” or “withCredentials( )” method?
Choose 2 answers

All credential bindings support the “Secret Text” and “Standard username and password” credential types.

Credential IDs are case Insensitive.

The credential types supported are defined by the binding plugin (or the resource being accessed.

Most credentials called from a pipeline have Global scope, not System scope.

Q54. Which is an invalid default project parameter?

Boolean

File

String

md5

Q55. You are given the task to install Jenkins and its prerequisites as part of an initiative toimplement CI/CD. After installing the operating system, you will need to make sure what language is available for Jenkins to utilize before you can successfully install it?

Perl

Python

Ruby

Java

Q56. One quality of an ideal build node K that it is_________.

ephemeral and replaceable

tailored to specific builds

on-master

static

Q57. You have taken over a build environment where Jenkins is responsible for scanning for changes made in a Git repository every hour and then applying that build to a few dozen web servers. As part of that job, Jenkins also is responsible for completing some scripted performance-based Visit us athttps://www.examsboost.com/test/cje/ Leading the way in IT testing and certification tools, www.pass4test.com tests and, depending on the defined results, marking the build as complete and notifying the team OR rolling back the build, notifying the team, and marking it as failed. You notice that the build itself is now taking longer than an hour to complete, which is affecting the push of new changes on occasion. What changes could you make to your Jenkins environment to alleviate the amount of time it takes to complete and test a build so that the hourly schedule is more likely to be kept?

Create additional Jenkins Masters and deploy the job to each one. Schedule the job staggered by 30 minutes on each one so that the additional master servers won’t be busy if the first job runs long.

Add one or more slave nodes to the environment, this will allow us to deploy code to multiple end points at one time. Break up the single job into multiple jobs so that each one can be triggered by the successful completion of the previous job to eliminate scheduling problems on beginning a new build in the event subsequent steps run longer than the intended time period.

None of these

Remove the performance testing from the build. Schedule performance testing as a separate job 30 minutes after the build runs and trigger a rollback if the performance testing fails at this point.

Q58. During a proposal, you need to quickly retrieve configuration for a demo of a project named “My Freestyle Project”, which is in the “Freestyles” folder, in a neat and easily-readable XML format using a REST API call. What is the correct syntax for the call?

http://:8080/job/My%20Freestyle%20Project/config.xml

http://:8080/job/Freestyles/job/My%20Freestyle%20Project/config.xml

http://:8080/job/Freestyles/job/My%20Freestyle%20Project/project.xml

http://:8080/job/My%20Freestyle%20Project/project.xml

Q59. Why Is the performance of a Jenkins master Improved by using a distributed builds architecture?

Because executors cannot be allocated on the master.

Because executors offloaded onto build nodes are not performant.

Because it prevents the CPU being overloaded during parallel polls.

Because it prevents builds from overloading a master’s CPU/memory.

Because builds cannot be run In parallel on a master.

Q60. A Freestyle job has the configuration shown here:

You run the following command from a Unix terminal: curl http: ///git/notifyCommit?
url-gitagithub.com: cloudbees/github test.git Will the Job be triggered?

It will not be triggered.

It will be triggered if the polling detects a change In any git branch.

It will be triggered if the polling detects a change In the git branch “master”.

It will be triggered if the polling detects a change in the git branch “development”.
