Nokia IS-IS Routing Protocol Exam FAQ: What Candidates Ask Most

What is the Nokia 4A0-112 exam?

The 4A0-112 exam is the official Nokia exam behind the Nokia Network Routing Specialist II certification, validating the skills measured by the Nokia IS-IS Routing Protocol credential. It sits at the Professional level of the Nokia certification program. It also connects to Nokia Certified Network Routing Specialist II (NRS II), Nokia Certified Service Routing Architect (SRA), so the knowledge you build here carries over to those tracks as well.

How many questions are on the 4A0-112 exam, and how much time do I get?

The 4A0-112 exam contains 40 questions to be completed within 90 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

Are there any prerequisites for the 4A0-112 exam?

No mandatory prerequisites. Nokia recommends knowledge of Ethernet, IP routing, and SR OS MD-CLI. Requirements can change when Nokia revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
