The C2090-313 exam, officially known as IBM DB2 11 Application Developer for z/OS, is the IBM test that leads to the IBM Certification certification at the Professional level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as IBM Certified Application Developer - DB2 11 for z/OS.

The C2090-313 exam contains 60 questions, and you have 90 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the PrepAwayTest test engines are the most reliable way to build that rhythm.

The passing score for the C2090-313 exam is 61%, and the official registration fee is $200 USD. If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.

No prerequisite exam required. Candidates should have practical experience developing applications for DB2 11 for z/OS.
