The 920-335 exam, officially titled BCM50 3.0 Installation and Initial Configuration, is the Nortel exam you pass to earn the Nortel Certified Support Specialist (NCSS) certification, a credential at the Specialist level. Passing it confirms the skills defined in the official exam outline, and it is associated with related credentials such as Nortel BCM Certification Track, 920-338 BCM50/200/400/450 Installation.

The 920-335 exam includes 40-45 questions and gives you 90 minutes to finish them. That is a tight pace per question, so get used to reading each stem once, flagging anything uncertain, and moving on rather than getting stuck. Running timed practice tests in the Fast2test desktop or online test engine is the most reliable way to build that rhythm before exam day.
