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.
For advanced source code management, Jenkins integrates with _________ to support different version control systems.
- Bitbucket
- Git
- Jenkins SCM plugin
- Jenkins Source Control
Jenkins integrates with Git for advanced source code management, allowing developers to manage and version control their code efficiently. Git is a popular distributed version control system.
When creating a Jenkins plugin for database connectivity, the primary concern should be _________ to ensure seamless integration with various database systems.
- Build automation
- JDBC implementation
- Network security
- UI design
The primary concern when creating a Jenkins plugin for database connectivity is the JDBC (Java Database Connectivity) implementation. This ensures seamless integration with various database systems, allowing Jenkins to interact with databases efficiently.
Which section in the Jenkins dashboard is typically used to manage plugins?
- Manage Jenkins
- Configure System
- Build Executor Status
- Jenkins Dashboard
The "Manage Jenkins" section in the Jenkins dashboard is typically used to manage plugins. This section provides access to various configuration options, including plugin installation and updates.
Jenkins integrates with containerization tools like Docker to create _________ environments for testing.
- Dynamic
- Isolated
- Reproducible
- Virtual
Jenkins integrates with Docker to create reproducible and isolated environments for testing. This allows for consistent and controlled testing environments, promoting reliability in the CI/CD process.
For automated testing in multi-branch pipelines, Jenkins utilizes the __________ file for defining branch-specific actions.
- Branchfile
- Configfile
- Jenkinsfile
- Pipelinefile
Jenkins uses the Jenkinsfile to define branch-specific actions in multi-branch pipelines. The Jenkinsfile contains the pipeline script that defines the stages and steps for each branch.
