CNCF-CBA: CNCF CBA (Certified Backstage Associate)
Master the Certified Backstage Associate (CBA) exam - the Backstage local development workflow (create-app, yarn dev, TypeScript, the packages/app + packages/backend monorepo, Docker image build), the framework and client-server architecture, configuration with app-config.yaml, the Software Catalog (catalog-info.yaml entities, kinds, annotations, locations, discovery, and troubleshooting), and customizing Backstage (frontend versus backend plugins, wiring plugins, editing React code in the App, and Material UI components).
$79 practice exams are gatekeeping. Mine are $9 because it should be. Written by someone who works in cloud and AI at Microsoft NZ — for people like us.
I just passed with a 777 (Yes, Seriously). This video helped me tremendously.
