Passing it earns you the Oracle Linux System Administration certification, a credential at the Professional level.

The Oracle Linux 5 and 6 System Administration exam includes ~60-75 questions to be completed within 120 minutes. Do the pacing math before exam day: with that many items on the clock, you need a steady rhythm and the discipline to flag a hard question and move on instead of stalling. Two or three full timed sessions with the ActualCollection test engine will show you exactly what that pace feels like, so time pressure stops being a factor on the real day.
To pass the Oracle Linux 5 and 6 System Administration exam you need ~64%, and the official registration fee is $245 USD (may vary by region). A retake is not discounted: a failed attempt means paying the full $245 USD (may vary by region) again, so treat your first sitting as the expensive one. A sensible rule is to book your seat only after you are scoring comfortably above the passing mark on the ActualCollection practice tests, not just squeaking past it once.
