Nokia Network Certifications and the Service Routing Path

Nokia’s technical learning portfolio spans several networking domains, but the Service Routing Certification program is the clearest place to understand the company’s exam-driven progression. The SRC track is designed for IP networking and technical-support professionals working with modern service-routing environments, and it combines written exams with practical lab validation at higher levels. Candidates should plan around the certification they want to earn rather than treating every 4A0 exam as an interchangeable networking test.

The current SRC structure centers on three milestones: Nokia Certified Network Routing Specialist I, Nokia Certified Network Routing Specialist II, and Nokia Certified Service Routing Architect. Nokia delivers written exams through Pearson VUE and practical lab exams virtually through Nokia. Written tests can be attempted in different orders, while the practical labs require the relevant written prerequisites to be complete. Nokia has also announced additional SRC program updates for 2026/27, so checking the live requirement page before booking is essential.

A useful study strategy follows the architecture of a service-provider network. Start with IP and service fundamentals, then develop routing-protocol and MPLS knowledge, and finally integrate advanced VPN services, quality of service, EVPN, and design tradeoffs. That sequence is more durable than memorizing commands because the certification path increasingly asks candidates to understand how technologies interact under operational constraints.

NRS I establishes the IP and service-routing foundation

The entry point is the Nokia Certified Network Routing Specialist I credential. Its current written requirement is 4A0-100 Nokia IP Networks and Services Fundamentals. The exam belongs at the beginning of a study path because later material assumes comfort with addressing, forwarding, routing behavior, Ethernet concepts, service models, and the relationship between the control plane and data plane. Engineers coming from enterprise networking should pay particular attention to how service-provider terminology and operational priorities differ.

NRS I preparation becomes stronger when candidates build small topologies and explain packet movement hop by hop. Rather than stopping at “this route is preferred,” ask which protocol installed it, which next hop is resolved, how the router forwards the packet, and what service context applies. That habit creates the reasoning foundation needed later for MPLS labels, VPN route distribution, traffic engineering, and troubleshooting across multiple protocol layers.

At this level, it helps to separate control-plane knowledge from the service outcome a customer actually sees. A route can be present in the table while a service still fails because the wrong next hop, interface state, encapsulation, filter, or service binding is involved. Practice moving from basic reachability to the relevant service context instead of treating every fault as a routing-protocol problem. That habit makes the later NRS II material easier because protocol behavior is always interpreted in relation to the traffic it is supposed to carry.

NRS II turns foundational routing into a multi-protocol skill set

NRS II expands the path into routing protocols and service architecture. Nokia currently requires either the 4A0-112 IS-IS Routing Protocol exam or the corresponding OSPF exam, plus 4A0-114 BGP Fundamentals for Services, 4A0-103 Multiprotocol Label Switching, and 4A0-104 Services Architecture, followed by the NRS II practical lab. The protocol choices should be learned as tools with different roles, not as isolated configuration chapters.

Candidates who prefer to consolidate the written requirement can use the 4A0-C03 NRS II composite exam, the current IS-IS composite option. Nokia also lists an OSPF-version composite on its current site. Whichever route is chosen, practical competence still matters because the lab expects candidates to integrate concepts rather than answer independent multiple-choice questions.

BGP and MPLS become meaningful when studied through services

Service-routing work uses BGP for far more than basic internet route exchange. Candidates need to understand policy, attributes, path selection, route propagation, and the way BGP participates in VPN services. The advanced 4A0-102 BGP for Internet Routing exam develops a deeper internet-routing perspective, while the NRS II BGP foundation creates the base required for service-provider designs. Lab work should include deliberate failures so that route visibility and policy effects can be diagnosed rather than guessed.

MPLS should be approached in the same integrated way. The value of 4A0-103 MPLS is not simply learning label terminology; it is understanding how label-switched forwarding supports scalable services and how the control plane establishes the information used by the forwarding plane. When candidates connect IGP reachability, label distribution, BGP, and service context, troubleshooting becomes much more systematic.

SRA focuses on advanced VPN, QoS, EVPN, and service design

The Service Routing Architect level deepens the service layer. Nokia’s current written set includes 4A0-105 Virtual Private LAN Services, 4A0-106 Virtual Private Routed Networks, 4A0-107 Quality of Service, and 4A0-115 Ethernet VPN Services, together with advanced BGP requirements and the SRA practical lab. These technologies are best studied as different answers to customer, scale, traffic, and operational requirements.

Nokia also offers the 4A0-C02 SRA composite exam to combine several written requirements. The composite route can reduce the number of separate bookings, but it does not reduce the conceptual breadth. A candidate still needs to move comfortably among route-policy behavior, VPN service models, traffic classification and queuing, resiliency, and the control-plane information that makes EVPN services possible.

Segment routing reflects the evolution of the service-routing toolkit

The current SRC catalog includes 4A0-116 Nokia Segment Routing. Segment routing is valuable because it changes how paths and services can be expressed across an MPLS-capable network, reducing reliance on some older signaling mechanisms while enabling policy-driven traffic steering. It should be studied in relation to the IGP, label stack behavior, resiliency, and operational observability rather than as a standalone feature.

For experienced engineers, the hardest part is often not learning a new command set but reconciling a new design model with years of earlier habits. Comparing traditional MPLS signaling with segment-routing behavior in the same topology helps expose what is actually changing. The most useful labs test convergence, path selection, failure handling, and service impact so that a candidate can reason from symptoms back to the control-plane state.

Retired exams must stay clearly separated from current requirements

Nokia’s live exam catalog now marks 4A0-108 Multicast Protocols as retired on September 8, 2026. Older study plans may still include the code because multicast knowledge remains important in many networks, but the retired status must not be confused with a current certification requirement. Candidates using historical notes should reconcile every code against the current Nokia page before purchasing an exam voucher.

This is a broader lesson for long-running networking programs. Exam codes, composite options, labs, and certification rules can change while the underlying technology remains relevant. A clean plan keeps two records: the current credential requirement and the technical topics the engineer still needs to master for the job. That prevents a program update from causing useful knowledge to be discarded or a retired exam from being presented as an active target.

The practical lab changes how candidates should prepare

Written exams can reward precise recognition, but the lab forces candidates to make a network work. That means preparation should include building, validating, breaking, and repairing configurations under time pressure. Create a repeatable workflow for checking interfaces, IGP adjacency, route tables, label state, BGP sessions, service bindings, and traffic behavior. A methodical verification sequence is faster than jumping randomly between commands when a service fails.

Documentation skills also matter. Keep a small set of topology notes, expected states, and diagnostic commands for each lab scenario. Before changing configuration, state the hypothesis being tested; after the change, verify whether the intended control-plane and forwarding behavior actually appeared. This practice reduces accidental fixes that mask the original cause and creates the disciplined troubleshooting style expected from advanced routing professionals.

Lab preparation should also include a disciplined verification sequence. Before changing configuration, capture the current state, identify the expected control-plane and forwarding behavior, and choose commands that test those expectations. After a change, verify the route, label or service state rather than assuming that a successful commit means the network is correct. This approach builds the diagnostic reasoning needed for virtual lab work and for production Nokia environments, where a configuration can be syntactically valid but operationally incomplete.

Nokia certification planning should follow the network role

The SRC program is not Nokia’s only learning domain. Nokia also maintains certification and training activity around optical networking, data-center fabrics, NSP, fixed networks, and other portfolio areas. A service-routing engineer should pursue those adjacent tracks only when the role genuinely crosses into them. The certification map is most useful when it mirrors the technology stack a person operates, designs, or supports rather than becoming a collection of unrelated exam codes.

For a routing-focused candidate, the progression is clear: establish IP fundamentals, build protocol depth, understand MPLS and services, then prove integration skills in labs. Recheck the live program before every major booking because Nokia is actively updating the SRC structure during 2026/27. That combination of current requirement awareness and hands-on network reasoning is more valuable than studying from an old exam list without understanding where each credential fits. With Nokia’s routing programme moving through a 2026–27 update cycle, candidates should separate certification-transition dates from durable routing skills. Keep current exam requirements in one checklist and protocol, MPLS, EVPN, segment-routing, service, and troubleshooting knowledge in another so programme changes do not create gaps in technical preparation.
