XK0-006 Practice Question: A development team uses Git for version control…
A development team uses Git for version control and wants to automate the testing of every commit pushed to the repository. They have a Jenkins server running on a Linux machine. The team wants to automatically trigger a Jenkins pipeline job whenever a push is made to the main branch of their Git repository. The Jenkins server is behind a firewall and cannot be accessed from the internet. The Git repository is hosted on a private GitHub repository. Which of the following is the best approach to trigger the Jenkins job automatically?
⚠ Common exam trap
A common mix-up: candidates assume webhooks are always the best automation trigger, but the firewall restriction makes polling the only practical solution when the Jenkins server cannot receive inbound connections.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure Jenkins to poll the Git repository every minute for changes.
Jenkins' polling mechanism allows it to periodically check the Git repository for changes, which works even when the Jenkins server is behind a firewall and cannot receive inbound webhooks. Polling every minute provides near-real-time automation without requiring internet access to the Jenkins server, making it the only viable option given the network constraint.
