Registration for Cisco Optical SONET Exam (SONET) officially runs USD (varies by region; legacy pricing not publicly listed), with Variable / Pass–Fail (Cisco specialist exams typically graded pass/fail) required to pass. Worth knowing before you book: retakes are billed at the same full USD (varies by region; legacy pricing not publicly listed), so a failed attempt doubles your spend. The smarter sequence is to measure yourself first. When your scores on the Actual4Dumps practice tests clear the passing line with room to spare, consistently, that is your signal to schedule the real thing.

No formal prerequisites specified, but recommended knowledge of optical networking technologies and Cisco optical equipment.
