Nokia's exam page publishes 40 questions for 4A0-100, the Nokia IP Networks and Services Fundamentals exam.
The exam runs 90 minutes; the appointment is 110 minutes because Nokia adds a 20-minute introductory survey.
Every written exam in the Service Routing Certification program carries the same published US$125 price.
Nokia lists mandatory prerequisites as none - 4A0-100 is the open entry point to the SRC program.
What the Nokia NRS I Exam Actually Is
The Nokia Network Routing Specialist I is the first certification in Nokia's Service Routing Certification program - Nokia's premier training and certification track for IP networking and technical-support professionals working on business VPNs, residential broadband, mobile backhaul, mobile core, and cloud-optimized networks. The single written exam that earns it is Nokia IP Networks and Services Fundamentals, exam code 4A0-100.
The format is published on Nokia's exam page, and it is the canonical sentence this site repeats everywhere the exam comes up: The Nokia IP Networks and Services Fundamentals exam (4A0-100) runs 40 questions in 90 minutes, costs US$125 per attempt, is offered in English only, and carries no mandatory prerequisites.
Delivery is stated word-for-word on Nokia's SRC exams page: Nokia written exams are delivered through Pearson VUE. Exams are offered online and at global test sites in a secure and proctored environment.
One calendar fact shapes every current NRS I plan: Nokia's 2026/27 program update retires the current OSPF-based 4A0-100 on February 8, 2027, blacks the exam out from February 9 to March 8, 2027, and opens two refreshed exams on March 9, 2027 - IP Networks and Services Fundamentals with SR OS (4A0-100) or with SR Linux (4A0-S01), either of which earns the same NRS I certification.

What the NRS I Exam Covers - and What Changes in 2027
Nokia publishes the candidate topic list through the course outline for Nokia IP Networks and Services Fundamentals rather than as a weighted domain table: the exam's scope is the fundamentals of IP networking and VPN service routing on Nokia's Service Router portfolio, and the exam page points candidates at the course objectives and modules for the full topic list.
The announced refresh defines what is changing. Per Nokia's program update, roughly 25% of the content changes: OSPF is replaced with IS-IS, and a new introduction to Segment Routing and EVPN services is added. The certification remains a single written exam, and a new SR Linux track arrives alongside the traditional SR OS track so candidates certify on the platform they actually work with.
The practical read: a sitting before February 8, 2027 faces the current OSPF-based exam; a sitting from March 9, 2027 faces the refreshed content with IS-IS, Segment Routing, and EVPN introductions, on a choice of SR OS or SR Linux. Nokia does not publish a passing score for the exam on its exam page - the result you receive is the pass or fail posted to your Student Portal.
At Home via OnVUE or at a Pearson VUE Test Center
Both routes are official. Nokia's SRC exams page states the delivery model word-for-word: Nokia written exams are delivered through Pearson VUE. Exams are offered online and at global test sites in a secure and proctored environment. Pearson VUE runs a dedicated Nokia OnVUE page where you log in through Nokia's Student Portal and schedule, reschedule, or cancel an online sitting.
The at-home route carries published minimums. Your computer runs Windows 10 or macOS 14 or higher with a working webcam, microphone, and speaker - headphones and headsets are not allowed - on a single display, because multi-monitor setups are not permitted. Your connection holds at least 6 Mbps download and 2 Mbps upload, stable, and every application except OnVUE closes. Prohibited on exam day: virtual machines and beta operating systems, phones, tablets, watches and earbuds, smart devices with recording or AI features, secondary or touchscreen displays, and VPN, corporate, or public networks.
Check-in follows Pearson's standard sequence: run and pass the System Test on the same device and network you will use on exam day, sit at a completely empty desk - a beverage in an unmarked container is the listed exception - and expect photos and a room scan. Nokia's own process note matters for planning: results can take up to five business days to reach Nokia, after which the result is sent to you and posted to your Student Portal page.
What the Nokia NRS I Attempt Costs
The exam fee is US$125 per attempt - Nokia's SRC exams page publishes one flat price for every written exam in the program - and 4A0-100's exam page confirms the same figure. The fee is paid at Pearson VUE registration; Nokia's program page routes all scheduling, rescheduling, and cancelling through the Student Portal login.
The retake rule is the most forgiving in the certification market, and it is published on the SRC exams page: if you fail a written exam, there is no waiting period before retaking it and no limit on how many times an exam can be rewritten. Every attempt still pays the full US$125, so a second-attempt pass totals US$250 in exam fees and a third-attempt pass totals US$375.
The full fee picture across the program - the US$375 NRS II composites, the US$400 SRA composite, and the euro-priced lab exams - sits in the Nokia SRC certification cost explainer. The service fee for a handled sitting is separate from Nokia's exam fee, and it is due only after the agreed result posts.
Where Nokia NRS I Attempts Go Wrong
The first failure pattern is the version trap with a hard date attached. Prep material in circulation mixes the current OSPF-based exam with the announced IS-IS-based refresh; a candidate who books in late January 2027 studies one blueprint and sits it weeks before retirement, while a candidate who books after March 9, 2027 faces IS-IS, Segment Routing, and EVPN content that older courses never mention. The exam you book and the material you trust have to match the same side of February 8, 2027.
The second pattern is treating entry level as trivial. Forty questions in 90 minutes leaves barely two minutes per question across the whole IP-fundamentals surface - addressing, routing basics, and service-routing concepts - and Nokia does not publish the passing score, so there is no published margin to plan against.
The third pattern is logistical. An unmet OnVUE minimum - a second monitor still attached, headphones within reach, a VPN or corporate network - can mean immediate cancellation and a forfeited US$125 before the first question. The 20-minute introductory survey inside the 110-minute appointment surprises candidates who planned their day around 90.

Handling It Safely
Every engagement starts from what Nokia and Pearson VUE publish today: the exam page facts, the OnVUE minimums and prohibited-technology list, the check-in sequence, and the Student Portal process. The plan is built inside those boundaries, not around them.
What we control is the quality, discretion, and privacy of the engagement: an honest feasibility answer before anything starts, a structured sitting plan, and a fee that follows the result. Your details stay private, we never ask for more than the sitting requires, and your account access is handled under the engagement's stated terms only.
And the honesty runs both directions: if the sitting does not look feasible for your situation - including a deadline that lands inside the February 9 to March 8, 2027 blackout - you hear that before anything starts, not after.
Pay After the Result Posts
The offer on this page is the site's real offer: Exam Assist handles the Nokia NRS I sitting end to end, and the service fee is due only after the agreed result posts. No pass, no service fee.
That structure is deliberate. You are not paying for effort or hours - you pay after you pass, and the fee waits for a posted result on your Nokia Student Portal record.
What Clients Say
My employer's Nokia partnership required the NRS I credential before the quarter closed. They confirmed the current 4A0-100 format against Nokia's exam page, handled the OnVUE sitting from my home office, and I paid after the pass posted to my Student Portal.
I nearly booked the wrong side of the retirement date - my prep material was all OSPF-based with eight weeks to go. They gave me a straight answer on timing, scheduled the exam sitting inside my window, and the fee waited for the result.
The five-day results wait was the part I had not planned around. They set the expectation up front, the exam sitting went clean on a single-monitor setup, and the certification showed in my portal within the week.
