The official outline for the 920-105 exam highlights these domains:

• Installation and Configuration (30%)
• Maintenance and Troubleshooting (25%)
• Symposium Call Center Server Overview (15%)

Weighting your study time toward the heavier domains first is a sensible strategy, and the Nortel NNCSS-Symposium Call Center Server Install. and Main practice questions at RealVCE follow the same objective structure.

Nortel recommends the following training resources for 920-105 exam candidates:

• Global Knowledge (historical)

Pairing official courses with timed practice sessions tends to work well, since one builds knowledge and the other builds exam-day rhythm.

The 920-105 exam gives you 90 minutes minutes to answer 52 - 64 questions. That pace leaves little room for hesitation, which is why rehearsing under a timer — for example with the online test engine at RealVCE, where you can set the session length just like the real test — is such a useful habit.

The online test engine is exclusive to RealVCE and runs on any electronic device — phone, tablet, or computer — with no installation barriers. It recreates the atmosphere of the real 920-105 exam: you set the test time the way it will be on exam day, work through the Nortel NNCSS-Symposium Call Center Server Install. and Main practice questions under that pressure, and at the end the engine marks the questions you got wrong and reminds you to practice them again next time. Over a few sessions, that loop turns weak areas into reliable ones.

To pass the 920-105 exam you need a score of 70% - 75%, and the registration fee is USD 125 - 150. Since each attempt costs the full fee, arriving over-prepared is cheaper than arriving under-prepared — timed mock sessions and repeated review of missed questions are the usual ways candidates close that gap.
