A/var/lib/jenkins

B/etc/jenkins

CWith your source code

DNone of these

Correct Answer: C. With your source code

Explanation:

The Jenkinsfile typically lives in the root of your project SCM repository.

Question 5

Which of the following practices are recommended for a Declarative Pipeline? Choose 3 answers

AUse the pipeline DSL to implement intricate networking and computational tasks that your Pipeline needs to do.

BSimplify the test/debug process and improve performance of your pipeline by defining separate steps for each Important task performed by the pipeline.

CEncapsulate common Jenkins logic within shared libraries when leveraging Declarative Pipelines.

DCall scripts written In Shell, Batch, Groovy, or Python to implement any complex logic required for your pipeline; call these scripts as steps in your pipeline.

EUse took such as Maven, Gradle, NPM, Ant, and Make to define most of the build work; cad these executables as steps In your pipeline.

Correct Answer: B. Simplify the test/debug process and improve performance of your pipeline by defining separate steps for each Important task performed by the pipeline.; C. Encapsulate common Jenkins logic within shared libraries when leveraging Declarative Pipelines.; E. Use took such as Maven, Gradle, NPM, Ant, and Make to define most of the build work; cad these executables as steps In your pipeline.

Question 6

Your company's DevOps staff is new to the continuous integration methodology. Some users are unclear on best practices, and you're hearing all kinds of feedback from them, some of it wrong. Which of the following statements is NOT a CI best practice?

ABuilds should be self-testing. That allows us maximum flexibility in spotting breaking changes and prevents a lot of staff time spent trying to both integrate a change and determine why it broke the build.

BWe should really use a single source repository. That makes it easier for us to manage what gets into the build pipeline.

CBuild everything manually, because that prevents errors.

DEvery commit should be built. That ensures we don't wind up with a lot of stray code and that any future change will be testable.

Correct Answer: C. Build everything manually, because that prevents errors.

Explanation:

CI relies heavily on automation, especially build automation, to enable the sped-up pace of code commits. If things are built manually, the pipeline is slowed down, and the ability to maintain a fast change pace is inhibited.

Question 7

Your Pipeline has three stages: build, test, and deploy. You want the build and test stages to run automatically (without requiring human interaction), but you want the deploy stage to require approval by a human being. How do you achieve that goal?

AUse an input step just before the deploy stage.

BThis is not possible using Pipeline, because a Pipeline must run from start to finish without human interaction.

CCreate a separate Pipeline to run the deploy stage.

DUse a stage step just before the deploy stage.

Correct Answer: A. Use an input step just before the deploy stage.

Question 8

On a single Jenkins master you have a folder named "Project1 ". I his folder contains three jobs: "job master", "job develop", and "Job edge". The job "job master" Is the latest built project and Is In a success state while the two other jobs are in falling state. Which statement is true about the folder "Project1"?

AIt reports its health as 'failed' {'Raining Cloud' weather icon), because that is the 'worst health of the sub-items'.

BIt reports its health as 'success' ('Sunny' weather icon), because that is the health of the 'latest built item.'

CIt must be configured with a dedicated 'Health Metric' setting before it can report its health with weather icons.

DIt does not report its health on the folder level; only Jobs report health.

Correct Answer: A. It reports its health as 'failed' {'Raining Cloud' weather icon), because that is the 'worst health of the sub-items'.

Question 9

Which answer best describes continuous delivery?

AA software development discipline where software is released continuously as part of an

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

CBuilding in 60 minutes or less.

DA software development practice where contributors are integrating their work very frequently

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

Explanation:

Continuous delivery is an extension of continuous integration. It means that the software CAN be released at any time.

Question 10

What programming language is Jenkins built in and is required to be installed prior to using Jenkins?

ARuby

BPython

CJava

D.NET

Correct Answer: C. Java

Explanation:

Jenkins is built with Java, which is required as a prerequisite to install.

Question 11

What's a benefit of a clean checkout over an incremental update?

AIt ensures the working directory is clean and not tampered with

BNone of these

CIt's faster

DIt ensures there are no mistakes

Correct Answer: A. It ensures the working directory is clean and not tampered with

Explanation:

A user, or previous build, could create or change a file in a workspace which could cause problems with future builds.

Question 12

How do you configure notifications in a Jenkinsfile?

Aemailext

Bnotice

Cemail

Dalert

Correct Answer: A. emailext

Question 13

You are working on a project that will build a Docker image. When the job completes it needs to trigger a build to deploy a container to your development environment for integration testing. How would you go about triggering the second build?

AYou could use the Parameterized Trigger Plugin to trigger from an upstream project.

BBoth 'Triggered by another project' and the 'Parameterized Trigger Plugin'

CUse the run() function passing the downstream projects name from within an upstream project build step.

DIn the downstream build, you can select 'Triggered by another project'

Correct Answer: B. Both 'Triggered by another project' and the 'Parameterized Trigger Plugin'

Explanation:

Both are options for triggering upstream and downstream projects.

Question 14

If you set "Child item with worst health" and "recursive" in the folder config, how is the health determined for the folder?

AOnly top-scoped projects will determine the folder's health

BNone of these

CFolders don't have health

DItems in nested sub-folders are used to calculate the folder's health.

Correct Answer: D. Items in nested sub-folders are used to calculate the folder's health.

Explanation:

Nested items determine folder health in this configuration.

Question 15

Where do you configure a shared global library?

AConfigure Global Security
