What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
What the exam covers
| Design and implement processes and communications | 10-15% |
| Design and implement a source control strategy | 10-15% |
| Design and implement build and release pipelines | 50-55% |
| Develop a security and compliance plan | 10-15% |
| Implement an instrumentation strategy | 5-10% |
Two sample questions
1. How do you define a variable group in a YAML pipeline?
- variables: - name: myVar value: myValue
- parameters: - group: my-variable-group
- variables: - group: my-variable-group — correct
- resources: - group: my-variable-group
Why: Variable groups are referenced in YAML pipelines using the 'variables: - group:' syntax, making the group's variables available to the pipeline.
2. You need to implement a pipeline that handles both hotfix and regular release deployments. Hotfixes should skip staging and deploy directly to production with approval. How should you structure this?
- Two separate pipelines with copied stages
- Deploy hotfixes through every stage anyway, including staging
- Deploy hotfixes by hand from a laptop, outside the pipeline
- One pipeline whose hotfix branches skip staging by a branch condition — correct
Why: Using conditions based on the source branch (e.g., hotfix/*) to conditionally skip staging stages in a single pipeline provides streamlined hotfix deployments while maintaining normal flow.
