Alcatel-Lucent Certification and the Nokia Learning Path

Alcatel-Lucent certification material still appears across older training records, exam references, and professional profiles, but the current networking certification ecosystem belongs to Nokia. After Nokia completed its acquisition of Alcatel-Lucent, the service-routing training lineage continued under Nokia Learning Services rather than remaining a separate Alcatel-Lucent certification program.

That transition matters because many exam codes survived the brand change. Candidates can encounter a 4A0 exam number in old Alcatel-Lucent material and then find the same or related code in the current Nokia Service Routing Certification program. The code alone does not tell the full story. Current candidates need to verify the live Nokia exam title, certification path, and program requirements rather than assuming every historical Alcatel-Lucent reference is still current.

The Alcatel-Lucent certification context is therefore best used as a bridge between legacy terminology and the current Nokia certification ecosystem. It preserves historical context for professionals who trained under Alcatel-Lucent while directing new candidates toward the live Nokia learning and certification structure.

Nokia Service Routing Certification is the current successor program

Nokia’s Service Routing Certification program is now the main certification path for IP networking and service-routing professionals working with Nokia platforms. The program currently includes Nokia Certified Network Routing Specialist I, Nokia Certified Network Routing Specialist II, and Nokia Certified Service Routing Architect.

NRS I is the entry point and develops the foundation needed for IP networking, Ethernet, addressing, routing, MPLS, and VPN services. NRS II adds deeper IP/MPLS and service-routing expertise, while SRA is the advanced architecture credential for professionals responsible for designing and supporting complex service-router networks.

The structure is more useful than treating a list of exam codes as independent tests. The certifications create a progression from fundamentals to implementation depth and then to architecture-level expertise. Candidates should understand which certification they are pursuing before choosing individual exams because the same exam can serve as a component of a broader path.

4A0 exam codes remain important, but Nokia branding is now authoritative

The current Nokia SRC exam catalog still uses the familiar 4A0 numbering scheme. For example, 4A0-100 is the current Nokia IP Networks and Services Fundamentals exam. It covers the foundational networking knowledge used across the service-routing program and is one of the clearest examples of an exam code that can be encountered in both historical Alcatel-Lucent material and current Nokia certification planning.

Other current written exams cover protocols and service technologies such as IS-IS, OSPF, BGP, MPLS, service architecture, VPLS, VPRN, quality of service, EVPN, and segment routing. Nokia also maintains composite and practical lab exams for higher-level certifications.

Candidates should therefore search by both code and current title. An older source may identify the technology correctly but use outdated program branding or describe a requirement that has since changed. The live Nokia exam catalog should govern current preparation and registration decisions.

NRS I and NRS II build different levels of routing expertise

NRS I is intended to establish the core networking foundation. Candidates need to understand packet forwarding, Ethernet, addressing, the TCP/IP model, routing concepts, MPLS, and VPN services well enough to work with Nokia service-routing environments. It is a good starting point for professionals who are new to Nokia IP networking or who want a structured baseline before moving into specialist material.

NRS II assumes a stronger foundation and develops deeper knowledge of routing protocols, IP/MPLS networks, layer 2 and layer 3 services, resiliency, and operational techniques. The value of this stage comes from being able to configure and reason about service-provider networking behavior rather than only recognize protocol definitions.

Because Nokia is modernizing the SRC program during 2026 and 2027, candidates should verify the active NRS I and NRS II requirements before building a long study plan. Program changes are introducing more current technologies such as segment routing and EVPN while retiring older material. A roadmap based on an old Alcatel-Lucent course list can therefore send a candidate toward exams that no longer represent the current path.

Service Routing Architect is the advanced certification target

The Nokia Certified Service Routing Architect credential is the highest-level certification in the current SRC program. It is designed for engineers who need to understand how to design, build, and support high-performing Nokia service-router networks across multiple technologies.

The current SRA path includes multiple written requirements and a practical lab component. Nokia also offers the 4A0-C02 SRA Composite Exam as an option that can replace a group of individual written exams within the certification requirements.

This composite structure is useful for experienced professionals who already have broad routing knowledge and want a more consolidated written assessment, but it does not eliminate the practical dimension of the architect certification. Candidates still need to understand how technologies interact in a real network rather than treating the composite exam as a shortcut around operational competence.

Written exams and practical labs validate different capabilities

Nokia delivers written exams through Pearson VUE, while practical exams are administered through Nokia. Written exams test whether the candidate understands the technologies, configuration principles, and design concepts associated with the certification. Practical labs require the candidate to apply that knowledge in a working environment.

This distinction is particularly important for advanced service-routing certifications. A candidate can memorize BGP attributes, MPLS terminology, or VPN concepts without being able to diagnose a live configuration problem. Lab work exposes whether the person can translate concepts into correct behavior, interpret outputs, troubleshoot failures, and make changes without destabilizing the network.

Professionals preparing through older Alcatel-Lucent material should make sure their labs use current Nokia software and current certification objectives. The underlying networking principles may remain useful, but syntax, supported features, defaults, and recommended designs can change across product generations.

Recertification keeps Nokia credentials tied to current technology

Nokia SRC certifications currently have a three-year validity period. Recertification is required to keep the designation active, and Nokia provides specific written or practical options depending on the certification level.

This matters because service-provider networking evolves continuously. EVPN, segment routing, automation, telemetry, and newer operational models change the skills expected of engineers even when long-standing technologies such as BGP and MPLS remain important. Recertification gives the program a mechanism to keep the credential aligned with the current platform and network architecture.

Legacy Alcatel-Lucent certification holders should therefore distinguish historical achievement from current certification status. An older credential may remain valuable on a professional history, but it should not automatically be presented as an active Nokia certification unless the current recertification requirements have been satisfied.

Transition planning should separate historical identity from current requirements

The Alcatel-Lucent name remains meaningful because it identifies the origin of a large body of service-routing training and certifications. Engineers who worked with Alcatel-Lucent platforms may have earned credentials that were highly relevant at the time and built skills that continue to transfer into Nokia environments.

Current candidates, however, should begin with Nokia. Verify the current certification target, identify the written and practical requirements, check whether any existing certification qualifies for exemptions, and use the live Nokia course and exam descriptions as the source of truth.

This approach preserves the value of historical knowledge without confusing it with current registration requirements. A legacy certification page can explain where the program came from, while the Nokia path explains what a candidate needs to do now.

The best path follows the network role, not the historical brand name

Professionals focused on IP fundamentals can begin with NRS I. Engineers working deeply with IP/MPLS and VPN services may align with NRS II. Senior engineers and architects responsible for complex service-routing design can work toward SRA. Other Nokia certification programs support data-center fabric, optical networks, fixed networks, 5G RAN, cloud-native RAN, and related technologies outside the SRC track.

The strongest certification plan starts with the technology and role the candidate actually supports. Someone searching for an old Alcatel-Lucent credential should ask what current Nokia certification now validates the same or evolved responsibility. That question leads to a more useful answer than simply looking for an unchanged exam title.

Alcatel-Lucent certification history still matters, but the live professional-development path is Nokia Learning Services. Candidates who make that distinction can use older knowledge intelligently while preparing for the requirements that employers and certification systems recognize today.

Engineers migrating from Alcatel-Lucent terminology should also review how Nokia currently groups products and learning objectives. Older course names may refer to familiar routing concepts while current exams place more emphasis on technologies that have become central to modern service-provider networks, including EVPN and segment routing. Mapping old terminology to the current syllabus can prevent unnecessary relearning while still exposing areas where the architecture has genuinely evolved.

Employers evaluating historical certifications should make the same distinction. An Alcatel-Lucent credential can still demonstrate relevant experience, especially when the professional continued working with the platform after the Nokia transition. However, hiring or project requirements that call for an active Nokia certification should be checked against the holder's current certification status rather than inferred from an older badge. For candidates working with Nokia routing platforms, a practical transition plan should separate durable IP/MPLS concepts from programme-specific exam requirements. That way, changes to the certification structure do not erase useful networking knowledge, while the live Nokia requirements still control what must be completed for the credential.
