What Candidates Ask About the Nortel 920-552 Exam

Can you give me an overview of the 920-552 exam?

The Nortel GSM BSS Operations and Maintenance exam (code: 920-552) is the official Nortel exam that leads to the NCSS certification. It sits at the Professional level of the Nortel certification track. It is also connected with related credentials such as GSM BTS 18000 Installation & Commissioning. Passing it proves to employers that your skills have been validated by Nortel itself, which is why the 920-552 credential keeps showing up in job postings.

Can I try the 920-552 practice questions before buying?

Yes. Dumpkiller offers a free 920-552 PDF demo so you can review the question style, difficulty, and explanations before committing to anything. After purchase, your Nortel GSM BSS Operations and Maintenance material includes 365 days of free updates, and if your product expires after that, you can extend the update service at a 50% discount from your member zone.

What happens if I do not pass the 920-552 exam, and how is my order delivered?

If you take the corresponding 920-552 exam within 60 days of your purchase and do not pass, you can apply for a full refund under our 100% Money Back Guarantee, subject to a few conditions: the failed exam must be the one matching your purchase; sitting the exam within 3 days of purchase does not qualify, since that leaves too little preparation time; downloading the material without actually taking the exam does not qualify; free materials and expired orders are excluded; and the candidate name must match the payer name. To apply, send a scanned copy of your enrollment slip together with your official Score Report (PDF) within 2 days after the exam, and claims are processed within 7 days. If you would rather not take a refund, you can exchange your purchase for two free products of equal value while keeping the update service on the product you originally bought.
