                                  Nortel 920-808 Exam FAQ — What Candidates Ask Most

                                  The 920-808 exam is the official Nortel exam for Nortel Real-Time Networking Technologies. Passing it earns you the Nortel Networks Certification (Legacy) credential. It is also connected to Nortel Networks Certification Program (NNCP), so what you learn carries over if you plan to pursue those paths as well. Employers treat the certification as verified proof of skill, which is why structured preparation with 2Pass4sure's practice questions pays off.

                                  No strict prerequisites documented; basic networking knowledge is recommended. Eligibility details can change, so before you register, confirm the current requirements on the official exam page.

                                  Yes. 2Pass4sure offers a free PDF demo of the Nortel Real-Time Networking Technologies practice questions on the samples page, so you can judge the format and quality yourself before paying anything. Every purchase also includes 365 days of free updates, and after the product expires you can extend the update service at a 50% discount from within your member zone.

                                  If you take the corresponding exam within 60 days of purchase and do not pass, 2Pass4sure backs you with a 100% money-back guarantee. To claim it, submit a scanned copy of your exam enrollment slip together with your official Score Report PDF within 2 days of the exam, and the refund is processed within 7 days. The guarantee does not apply to attempts made within the first 3 days after purchase, to products downloaded without actually sitting the exam, or to free materials and expired orders, and the candidate name must match the payer's name. If you would rather have study material than money, you can instead exchange for two additional exam products of equal value, free of charge, while keeping the update service on your original purchase. Delivery itself is instant: your download is available right after payment and a copy reaches your mailbox within one minute — if nothing arrives within 2 hours, contact customer service. You may install the product on as many computers as you need.
