Q29. Which of the following “agent” directives are not valid in Declarative Pipeline?

agent (dockerfile {filename ‘ Dockerfile’ } }

agent { label ‘Minux’ }

agent docker

agent { docker ‘ centos:latest’ }

agent none

Q30. The QA department has been having issues locating their work on the Jenkins server. As a result, their manager has asked for the jobs (projects) to be better organized. Which most correct answer can you use to organize projects?

Folders and views

Relational Database

Folders

Views

You can organize projects in Jenkins with folders and views.

Q31. What’s the difference between pushing and pulling code from a CI perspective?

Pulling is more efficient.

When the source informs the build system of a code change, that’s pushing. When the build system asks if there are changes to the source code, that’s pulling

Pushing uses more resources.

When the source informs the build system of a code change, that’s pulling. When the build system asks if there are changes to the source code, that’s pushing

Pushing is generally preferred as it assures the action is only performed as changes are made.

Q32. In Jenkins, a trigger commonly refers to a mechanism that automatically_________.

updates plugins

starts the build of a job

sends notification once the build is completed

detects code changes in the repository

Q33. 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.

Q34. What’s an example of SCM software?

Jenkins

Subversion

Git

Both Git and Subversion

Git and Subversion are common SCM software choices.

Q35. How do you add a new folder?

Click “New Item” in the left dashboard panel, then select “Folder”

None of these

Add a folder on the Jenkins master file system in /var/lib/jenkins

You can add one from another project’s “Configuration” view

Q36. What directive do you use for a declarative pipeline?

config {..}

project {..}

pipeline {..}

test {..}

Declarative pipelines use the “pipeline” directive.

Q37. What’s the SDLC?

Sloan Digital Legal Conference

Super Digital Life Chain

None of these

Software Development Life Cycle

The SDLC is contained in CI/CD concepts.

Q38. When you upgrade a plugin and find an issue in the new version, how ran you move hade to the previously installed version? Choose 2 answers

Use the pluginManager.downgrade method in the script console.

Select the version you want to use in the global configuration section for this plugin.

Select one of the previous versions in the Plugin Manager.

Manually download and install the previously installed version.

Use the “downgradeplugin” command In the Jenkins CI I

Use the button on the Plugin Manager that allows a downgrade to the previously installed version.

Q39. Which is a common branching strategy?

Feature branching

All are common

Release branching

Developer branching

These are all common branching strategies.

Q40. 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.

Q41. How do you navigate to the matrix-based security section of Jenkins?

Manage Jenkins -> Configure Global Security

Manage Jenkins -> Configure System

None of these

Manage Jenkins -> Configure Global Options

This is how you would use the dashboard to navigate to the Security section.

Q42. You’re a DevOps engineer in charge of your team’s Jenkins server. You have a particular stage in your pipeline that you want to run on a particular build node. You have to have Apache installed on this node. Assuming the node has been appropriately labeled, “apache”, how would you ensure this stage ran on that node?

apache agent

agent { label ‘apache’ }

agent( ‘apache’ )

apache’ { agent }

Example: stage(‘deploy’) { agent { label ‘apache’ } steps { sh “if ![ -d ‘/var/www/html/rectangles/all/${env.BRANCH_NAME}’ ]; then mkdir /var/www/html/rectangles/all/${env.BRANCH_NAME}; fi” sh “cp dist/rectangle_${env.MAJOR_VERSION}.${env.BUILD_NUMBER}.jar /var/www/html/rectangles/all/${env.BRANCH_NAME}/” }

Q43. What is Jenkins matrix-based security?

None of these

An option that doesn’t come with Jenkins by default

An option that doesn’t allow user specific permissions

Allows the administrator to grant very specific permissions to users and groups.

Jenkins permissions are defined in a matrix-like structure, in which the administrator can set security based on a user or user group.

Q44. You have started work on a project with Docker integration. What is the proper syntax to invoke a Docker agent?

agent {docker ‘openjdk’}

deploy { docker ‘openjdk’ }

docker ‘openjdk’ { install: true }

docker { agent ‘openjdk:latest’ }

“agent {docker ‘openjdk’}” is the correct syntax to invoke a docker agent with the ‘openjdk’ image. This syntax will provide the latest version.

Q45. 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”?

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

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

It must be configured with a dedicated “Health Metric” setting before it can report its health with weather icons.

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

Q46. Which is a valid environment variable string interpolation?

“${VARIABLE}”

Both “${VARIABLE}” and $VARIABLE

%{VARIABLE}

$VARIABLE

These are both valid forms of interpolation.

Q47. Which of the following are true about the structure of a Declarative Pipeline? Choose 2 answers

Any Pipeline DSL code that Implements complex computational tasks must be located outside any stage block.

Steps are the logical segmentation of a Pipeline; they contain stages that define actual tasks.

Stages are the logical segmentation of a Pipeline; they contain steps that define actual tasks.

Each pipeline must have a global agent specification.

All stages in a Pipeline must execute on the same type of agent.

Q48. Which are benefits of binary reuse (compiling once and reusing the built artifact across the rest of the pipeline)? Choose 3 answers

guarantees the same source is tested in each environment

allows the inclusion of environment configurations into the artifact

enables selectively linking stubs and real classes representing an external interface

ensures a single version b used throughout the pipeline

allows a shorter cycle time
