Provyn Prep · Docker and Kubernetes competency
Operations in the Docker and Kubernetes assessment
Operations is one of the areas a Provyn Docker and Kubernetes credential scores separately, so a recruiter can see it on its own rather than averaged into one number. This guide explains what it covers, how it is tested and what to practice.
What it covers
Running workloads day to day: rollouts and rollbacks, liveness and readiness probes, autoscaling and persistent storage.
Topics in the practice set for this area
- K8s deployments
- K8s probes
- K8s autoscaling
- storage
How it is tested
In the timed assessment, questions in this area use these formats: incident walkthrough, matching, multiple choice, put the steps in order, short answer. Each attempt draws its own set of questions, and this area gets its own sub-score on the credential when the attempt includes enough questions from it. The assessment questions themselves are never published; the practice set below is written separately for study.
What to practice
- Perform a rolling update and a rollback on a local cluster.
- Explain the difference between a liveness and a readiness probe and what each failure does.
- Set resource requests and limits and watch how the scheduler and autoscaler react.
Try a practice question
From the free practice set (6 questions in this area). Answers and explanations are in the practice set.
- `kubectl apply -f file.yaml` is:
- Liveness probe failure means K8s will:
- ReadinessProbe failure means K8s will:
Practice before the real thing
Both are free and use practice questions only, never questions from the real assessment.
