Platform Engineering Overview Quiz
1. What is the core goal of platform engineering?
Answer and explanation
Understand developer needs and provide approved self-service APIs, CLIs, portals, templates and operational support as an internal product. It does not eliminate operations teams or assume every application responsibility.
2. How should Start, Advance, Excel and tool mappings be interpreted?
Answer and explanation
They organize improvement tasks in AWS platform-engineering guidance. Advance discusses IaC/self-service automation; this guide’s Kubernetes mappings are teaching examples, not official certification scores or a universal sequence.
3. How do platform engineering, DevOps and SRE relate?
Answer and explanation
They are complementary: platforms emphasize developer experience/reusable products, DevOps collaboration/delivery, and SRE reliability/operations engineering. Team structures and hierarchy are not universal.
4. What are the IDP layers and the scope of a Backstage portal?
Answer and explanation
Interface, orchestration, resources and infrastructure form a reference model. A Backstage-style portal is part of the interface, not a replacement for provisioning, policy, runtime, documentation and support.
5. Can deviating from a Golden Path bypass mandatory security policy?
Answer and explanation
No. It is a supported recommended path, but exceptions still follow organizational approval and mandatory security/data policies. It is not guaranteed optimal for every case.
6. Does one WebApplication always make kro create Deployments, RDS and IAM?
Answer and explanation
No. WebApplication is an example custom API requiring an RGD/CRD. kro manages the declared Kubernetes resources; authorized ACK service controllers call AWS APIs. Resource combinations, readiness and deletion policies depend on the definitions.
7. What are current DORA metrics and how should they be used?
Answer and explanation
Change lead time, deployment frequency, failed deployment recovery time, change fail rate and deployment rework rate. Improve service/team delivery and stability rather than substitute generic MTTR or individual rankings. Measurement can start before Excel.
8. Do guardrails automatically guarantee security and compliance?
Answer and explanation
No. Enforce and verify policies, bypass/exception handling, permissions and changes, with audit and recovery. Guardrails do not replace application data-handling responsibilities or assessment of legal requirements.
