Domain names above reflect the current official curriculum's topic areas; exact weightings are set by the Linux Foundation/CNCF and revised periodically, so check their published curriculum for the current breakdown.

Why it's worth it

Customizing Backstage is the largest domain at 32%, which is an honest reflection of the product: almost nobody runs it unmodified, and the work is mostly plugins, templates and catalog integration. The narrowest exam in the catalogue, and the one where "do you actually use this" matters most. If your company has not adopted Backstage, this certifies a skill you cannot practise.

Prep tips

• Run a Backstage instance locally and add a plugin. A third of the exam is customisation and there is no way to learn it from documentation alone.
• The catalog is 22% and it is the conceptual heart: entity kinds, relations, and how descriptors get discovered. Get this right and the rest follows.
• Development workflow at 24% assumes familiarity with the local development loop, which is Node-based and unlike the rest of the cloud native catalogue.
