Send notifications by multiple channels (email, chat room, PagerDuty, etc.) to make sure they are received.

Periodically change the recipient of emails, to make sure they are not classified as spam.

NO.18 Which of the following build steps is most appropriate to use to publish the artifact files of a build?

Copy artifact files to the agent file system

Upload the artifact files to a central artifact repository.

Stash artifact files.

Commit the artifact files to git.

NO.19 Which of the following is true about resuming a Declarative Pipeline?

Declarative Pipelines cab be restarted after a Jenkins failure but not after a transient outage (such as a network failure or disk space exhaustion).

Declarative Pipelines can be resumed only after a transient outage (such as a network failure or disk space exhaustion).

All Declarative Pipelines are restartable by default, with the same inputs (commit to build, parameters, etc) as the original run. Any data that was built In the original run Is available only If the preserveStashes() optionIs specified In the Jenkinsfile

Declarative Pipelines that use Docker containers can not be resumed because the docker APIs that Jenkins calls to createthe container are not serialized

A Declarative Pipeline can be restarted only If the preserveStashes() option Is set In the pipeline.

NO.20 Yon are an administrator of a base Jenkins master with the recommended plugin set and you want to connect a new agent using SSH. Authentication on the remote node that will host the agent is done with an SSH key pair which your users must NOT be able to see or access. Which of the following is TRUE assuming your users do not have admin rights?

Use a credential “SSH Username with private key”, restricted to the Scope “System”, for the node’s SSH authentication.

You cannot use an SSH key-pair. Configure a password for the agent’s SSH user, and create a credential of type “Username with password” for the node’s SSH authentication.

Use a credential “SSH Username with private key”, restricted to the Scope “Agents”, for the node’s SSH authentication.

The SSH key will be stored in the JENKINS_HOME/.ssh folder. Configure the agent to use a key from the “standard” SSH folder.

NO.21 How can you configure a Declarative Pipeline to record the fingerprint of an artifact?

CaII the fingerprintArtifact() step immediately after the archiveArtifacts( ) step.

Enable the Declarative Pipeline ‘enableFingerprints’ ‘option’ .

Set the Fingerprint Artifacts global configuration option.

Set the “fingerprint: true” argument for the archiveArtifactsQ step.

No action is required; Declarative Pipelines automatically record a fingerprint for each artifact.

NO.22 Which enables you to use artifacts from a completed build in the workspace of the currently running build?

Jenkins core

Copy Artifact plugin.

Rebuild plugin.

ArtifactDeployer plugin.

NO.23 Which can be defined in and limited to a specific folder and its subfolders? Choose 4 answers

Permissions to run jobs and Pipeline

Credentials

View definitions

Plugins

Pipeline shared libraries

NO.24 Which practices optimize performance on large systems? Choose 2 answers

Run all builds on agents and never on the master itself.

Use the maximum number of executors at all times and avoid using labels.

Avoid modifying Java parameters that control heap size and garbage collection.

Use plugins as much as possible.

Allocate specific masters for different build types and teams.

NO.25 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.

NO.26 Which job type Is always available In Jenkins without additional plugins?

Ant project

Make project

Grade project

Pipeline project

Freestyle project

NO.27 You need to automate the deployment of 20 base Jenkins masters. I or this, you set the system property jenkins.install.runSetupWizard to the Value “false”.
Which Is TRUF about your Jenkins masters?

No default administrator account is created; you have to configure security manually.

A default administrator account is created with username “admin” and password “ad

A default administrator account is created with username “admin” and password from the file JENKINS_HOME/secrets/initialAdminPassword

A default administrator account is created and you cannot re-enable security.

NO.28 A unit test_________.

tests an Individual unit a component

verifies cross-functionalities

verifies that the complete software matches the specifications it was written to fulfill

is written when an Integration or multi-environment bog is fixed

NO.29 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”.

NO.30 Which of the following are true when using environment directives in a Declarative Pipeline?
Choose 3 answers

If an environment variable b enclosed In single quotes, the Pipeline DSL dereferences the variable on the master’s JVM and passes the calculated string to the sh or bat step; if the environment variable Is enclosed in double quotes, the name of the environment variable itself is passed to the “sh” or ‘bat” step and the shell interpreter on the agent dereferences the variable.

If an environment variable Is enclosed In double quotes, the Pipeline DSL dereferences the variable on the master’s JVM and passes the calculated string to the sh or bat step; if the environment variable isenclosed in single quotes, thename of the environment variable itself is passed to the “sh” or “bat” step and the shell interpreter on the agent dereferences the variable.

A Declarative Pipeline can use environment variables defined In Jenkins Itself (such as BUILD_NUMBER and JENKINS^URL), environment variables defined in an installed plugin (such as GIT.COMMIT or GIT .BRANCH, defined in the Git plugin), or environment variables that are coded as directives in the Pipeline itself; the semantics are identical for all environment variables.

An environment variable can be specified globally (to apply to all steps in the pipeline), for an individual step, or for one or more specified steps In the Pipeline,

NO.31 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

NO.32 Which is the about the “Build Triggers” functionality in Jenkins?

It allows you to customize what specific IP address will never be able to trigger a build.

It allows you to trigger a build under certain conditions, such as GitHub/BitBucket push events, deployment ratifications,

It can only be configured on Freestyle projects.

It allows you to customize the mail to be sent to developers after a failing build.

NO.33 DevOps teams can implement traceability of artifacts in a continuous delivery pipeline by using

the Downstream Builds plugin

manual recording

the Pipeline plugin to fingerprint files

Pipeline labels

NO.34 What is the purpose of the “Manage Old Data” screen under “Manage Jenkins”?

Delete artifacts, togs, and backups that are no longer required.

Clean up workspaces left by deleted Jenkins users.

Delete outdated configurations left by uninstalled, deleted, or upgraded plugins.

Delete or restore old credentials details.

Prepare for migration from Jenkins 1 to Jenkins 2.

Choose 3 answers

Automated deployment to the production environment.

Collaboration among Dev, QA and Ops.

Automated tests after each commit

Automated builds after each commit.

Frequent commits to source code repository.

NO.36 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.

NO.37 You are using GitHub repository scanning (in a project of type “GitHub Organization”) with the Pipeline lenkinsfile Project Recognizer. In this case, which repositories under the organization will have Multibranch projects automatically created for them?
