In a large-scale setup, Jenkins __________ is crucial for maintaining an efficient build process.
- Distributed Build
- Failover
- Load Balancing
- Scalability
In a large-scale setup, Load Balancing is crucial for maintaining an efficient build process. Load balancing distributes build jobs across multiple build agents, ensuring optimal resource utilization and faster build times.
Which feature in Jenkins is used to manage job dependencies in a complex workflow?
- Build Triggers
- Downstream/Upstream Projects
- Parameterized Builds
- Pipeline Stages
The Downstream/Upstream Projects feature in Jenkins is used to manage job dependencies in a complex workflow. It allows one job to trigger the execution of downstream jobs based on the completion of the upstream job.
For a Jenkins pipeline requiring dynamic parameters based on user input, integrating __________ functionality would be most appropriate.
- Dynamic Variable Expansion
- Input Step
- Parameterized Trigger
- User Choice Parameter
The Input Step in Jenkins pipelines allows dynamic parameters based on user input, providing flexibility in pipeline execution based on user choices.
In a scenario where a Jenkins plugin is causing system instability, the best course of action is to __________.
- Disable the plugin and monitor system stability
- Ignore the issue and continue with the existing setup
- Restart Jenkins master server
- Uninstall the plugin and find an alternative
The best course of action is to uninstall the problematic plugin and find a stable alternative. Disabling may not be sufficient, as the plugin might still have an impact on the system.
How does Jenkins typically trigger a build after a commit is made in a source control tool like Git or SVN?
- Automatic Scheduler
- Manual Trigger by Developer
- Polling SCM
- Triggered by Jenkins Master
Jenkins typically triggers a build after a commit using the "Polling SCM" method. It periodically checks the source control system for changes, and if a change is detected, it initiates a build.
In terms of disaster recovery, what is an important consideration when using Jenkins in a cloud environment?
- Data isolation and redundancy
- Frequent manual backups
- Jenkins version compatibility
- Network security measures
In a cloud environment, an important consideration for disaster recovery is ensuring data isolation and redundancy. This helps safeguard against data loss and ensures availability even in the event of infrastructure failures.
Which basic feature should be set up in Jenkins to start implementing CI/CD pipelines?
- Build triggers
- Email notifications
- Source code version control
- User authentication
Source code version control is a basic feature to set up in Jenkins for implementing CI/CD pipelines. It allows tracking changes, managing versions, and facilitating collaboration among team members.
In Pipeline as Code, what is the significance of the 'Jenkinsfile'?
- Declarative definition of pipelines
- Jenkins server configuration file
- Pipeline execution log
- Placeholder for environment variables
The 'Jenkinsfile' is a declarative definition of pipelines in Pipeline as Code. It allows defining the entire build process, including stages, steps, and post-build actions, directly within version control, enhancing transparency and traceability.
A company needs to ensure zero-downtime deployments in their Jenkins pipeline using containerization. They should implement a __________ strategy.
- Blue-Green deployment
- Canary deployment
- Rolling deployment
- Shadow deployment
To ensure zero-downtime deployments, a Rolling deployment strategy can be implemented. It involves gradually replacing instances of the previous version with the new one, minimizing downtime.
In Jenkins, a ________ is a sequence of steps that define how to build and deploy the application.
- Build Plan
- Job
- Pipeline
- Workflow
In Jenkins, a Pipeline is a sequence of steps that defines how to build, test, and deploy the application. It allows for the automation and visualization of the entire build process.
