Pass the CloudBees Jenkins Engineer CCJE Questions and answers with CertsForce

Operations Center enables you to interconnect different CI systems, such as CloudBees CodeShip and Jenkins

It is easier to share resources among Jenkins masters that are connected to the same Operations Center.

It is easier to run Pipelines on the Operations Center because it can retrieve resources from all connected masters.

Operations Center handles the build toad more efficiently by scheduling tasks on idle Jenkins masters.

It Is easier to perform administration tasks (such as upgrading a plugin) on a group of masters that are attached to the same Operations Center.

Scripted Pipelines usually execute significantly faster than the comparable Declarative Pipeline.

Declarative Pipelines usually use the "agent" section to define the node where the code should execute but the "node" parameter can be used instead and allows for additional options such as "customWorkspace’’.

Scripted Pipelines require extensive knowledge of the Apache Groovy syntax wher ease Declarative Pipelines can be implemented with minimal understanding of Groovy and so have a lower risk of syntax errors than Scripted Pipelines.

You can use the Declarative Directive Generator to help structure statements for Declarative Pipelines and use the Snippet Generator to help structure statements for Scripted Pipelines.

Scripted Pipelines can implement some functionality that Declarative Pipeline syntax does not support, although small bits of scripted syntax can be included In a Declarative Pipeline by using the "script" step.

Any OPTIONAL plugins that are missing will be installed.

Any REQUIRED plugins that were already installed may be upgraded, depending on Beekeeper configuration options.

No operation will be performed on OPTIONAL plugins.

All the plugins in the CAP Collection will be replaced by the versions specified in the target CloudBees Core version.

Any REQUIRED plugins that are missing will be Instated.

Specifies the set of features, feature versions, and feature dependencies that are either verified or trusted, depending on the degree of testing they have received.

Runs security metrics toots on the duster to ensure that no installed plugins have security vulnerabilities.

Specifies the set of plugins, plugin versions, and plugin dependencies that are ether verified or trusted, depending on the degree of testing they have received.

Tests all installed plugins to ensure that they are compatible with all other the CloudBees Core or Jenkins release you are running.

Specifies the set of apps, app versions, and app dependencies that are either verified or trusted, depending on the degree of testing they have received.

Encapsulate common Jenkins logic within shared Iibraries when leveraging Declarative Pipelines.

Use the pipeline DSL to implement Intricate networking and computational tasks that your Pipeline needs to do.

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

Use toots such as Maven, Gradle, NPM, Ant, and Make to define most of the build work; call these executables as steps in your pipeline.

Call 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.

Purchase the fingerprint license and install the Jenkins fingerprint service pack.

Enable "record fingerprints of files" in the post-build actions section of a Job to track usage.

Use a laptop or personal computer with an integrated fingerprint scanner.

All of the above.
