15 to 30 random questions in 15 to 30 minutes, by the level you choose: ci/cd, release strategies, terraform, ansible, sre, dora, devsecops. After you submit you get your score, your strong and weak topics, and the right answer with an explanation for every question.

The test covers 13 topics across three levels. Each attempt picks 15 to 30 questions at random, by the level you choose, so every attempt is different.
One question from each level, the way they appear in the test. A new set comes on the 1st of every month. Try it, then open the answer.
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'mvn -B package'
}
}
}
}Answer: Run the pipeline on any available agent that has a free executor. agent decides where the work runs. any lets Jenkins pick any available agent; you can instead pick one by label, use a Docker image, or say none and choose per stage. Who may start a build is set by Jenkins permissions, not by the agent section.
Answer: From commit to the change running in production. DORA lead time runs from code committed to code successfully running in production, so it measures the delivery pipeline: review, CI, waiting and release. Ticket-to-done is a wider product measure, and build time is only one part.
steps:
- name: A
run: false | true
- name: B
shell: bash
run: false | trueAnswer: A passes and B fails, because only an explicit shell: bash adds -o pipefail. With no shell key, Linux steps run as bash -e {0}, so a pipe returns the status of its last command and false | true passes. shell: bash runs bash --noprofile --norc -eo pipefail {0}, so the failing false fails step B.
Take the full DevOps mock test: 15 to 30 questions and 15 to 30 minutes, by level.
A question counts as right only when you pick exactly the right option, or all the right options where it says so; a question left blank counts as wrong. Your score is the share of the test's questions you got right (15 to 30, by level). The result also scores every topic, so you know what to revise before the interview.
Yes. The DevOps mock test is free. You need a free CoreHRx Jobs account to start it, so your score and the topics to work on are saved.
It depends on the level: Fresher has 15 questions in 15 minutes, Intermediate has 20 questions in 20 minutes, Experienced has 30 questions in 30 minutes. They are multiple-choice questions picked at random from a larger bank of DevOps questions at your level, so every attempt is different.
The questions cover Terraform, GitHub Actions, Release Strategies, Ansible, Monitoring and Alerting, SRE and Error Budgets, Jenkins, CI/CD Basics, DevSecOps, GitLab CI, Azure DevOps Pipelines, Secrets Management, DORA Metrics. Your result shows how you did in each topic.
Fresher if you are a student or have less than a year of experience, Intermediate for 1 to 5 years at work, and Experienced for 5 years or more.
Only your best DevOps score, and only when it is 60% or more. It shows on the job applications you send on CoreHRx. Lower scores stay private.
Yes, up to 10 tests a day. Each attempt picks questions you have not seen recently first.
