Domain overview
This domain covers the practices surrounding GitOps beyond core principles: managing configuration across many clusters, handling external dependencies such as Helm charts, and understanding the operator's role in reconciliation. Questions are scenario-based, asking you to choose the best strategy for scale, consistency, and regional variation in a Kubernetes environment.
Exam objectives
Using Kustomize overlays with a shared base to keep config identical while allowing regional variation
Managing external Helm chart dependencies via declarative sources such as HelmRepository and GitRepository CRDs
The GitOps operator's role in the reconciliation phase: detecting drift and applying desired state
Strategies for configuration at scale: hierarchical repos, Kustomize, and Helm with per-cluster values
Duplicating full manifests per cluster instead of using a shared base with overlays, which breaks consistency and increases drift
Treating Helm charts as imperative installs rather than declaring them as versioned sources reconciled by the operator
Assuming the operator only deploys once, ignoring its continuous reconciliation and drift-correction responsibility

18In the context of a CI/CD pipeline, where does the 'GitOps' bridge typically occur?
19How does the GitOps pattern simplify the audit process for a regulatory environment?
20What is the most effective approach to handle 'secrets' in GitOps when you require strict compliance that mandates secrets never exist in plain text in the repo?
21In a GitOps environment, what is the best strategy for managing external dependencies (like Helm charts)?
22Which action should a developer take to deploy a new version of an application in a GitOps-based workflow?
23What is the primary function of an 'Admission Controller' in a GitOps-based DevSecOps workflow?
24Which of the following describes the 'Declarative' aspect of GitOps?
25Why do you use a separate repository for application code and application manifests (deployment manifests) in GitOps?
26You are managing a global cluster setup with GitOps. How do you handle configuration that must be identical across all clusters while allowing for regional variations?
27When mapping traditional CI/CD to GitOps, which component from the traditional world is often 'decommissioned' or replaced?
28What is the primary role of the GitOps operator during the reconciliation phase?

39Which TWO of the following are common pitfalls when integrating DevSecOps into a GitOps pipeline?
40Which THREE of these practices are essential to successfully transition from traditional CI/CD to GitOps?
41A security auditor asks how your team handles secret management in a GitOps environment without exposing sensitive credentials in the Git repository. What is the standard GitOps practice for this requirement?
42Your team is integrating a CI pipeline with a GitOps delivery model. Which of the following tasks should remain in the CI pipeline, and which should be moved to the CD/GitOps reconciliation process?
43When implementing DevSecOps within a GitOps workflow, where should the automated policy enforcement (like OPA/Gatekeeper) occur?
44You are migrating a legacy application deployment process to GitOps. The application requires a specific sequence of database migrations to run before the new container version is deployed. How do you implement this in a GitOps-friendly way?
45In the context of 'Configuration as Code', why is it considered a best practice to use a declarative manifest format (like YAML) rather than imperative commands?

50Your platform team runs a GitOps operator that continuously reconciles a Kubernetes cluster against a Git repository. A compliance auditor asks how you can prove that no unapproved manual changes have been applied to production over the last 90 days. Which practice should you implement to satisfy this requirement?
51A platform team runs a GitOps operator that continuously reconciles cluster state from a Git repository. A compliance auditor asks how the team can prove which commit produced the configuration currently running in production six weeks ago, after many merges and rollbacks. Which practice best satisfies this requirement?

53An organization separates its GitOps repositories into an application repo and an environment configuration repo. Developers merge frequently into the application repo, while the environment repo pins image digests. A release engineer must promote a tested build from staging to production.
