I switched from a PHP background and 1Z0-900 felt overwhelming at first. The JMS messaging and WebSocket API questions here are particularly well thought out. Two months of steady practice and I cleared it.
Coming from Spring, CDI and EJB idioms felt foreign at first. The question variety here helped me build real confidence with Java EE patterns.
EJB lifecycle questions are no joke. Worth every drill.
Some of the JSF managed bean questions felt lighter than what I saw on exam day. But the CDI, interceptors, and batch processing sections were solid preparation. A fair resource for this certification overall.
