The Nokia Scalable IP Networks (4A0-100 / IP Networks and Services Fundamentals) credential validates a candidate’s foundational knowledge of scalable IP networking, routing, switching, and basic service technologies. It is designed for network engineers, support staff, administrators, and others who work with IP networks, or are entering roles that require skills in service routing, VPNs, and basic enterprise or service provider IP infrastructure. No prior prerequisites are required, making it suitable for individuals starting in IP networking or those formalizing foundational knowledge.

Key knowledge areas include:
– Understanding the TCP/IP layered model and protocol stack fundamentals
– Ethernet technologies, MAC addressing, VLANs, and Ethernet redundancy
– IP addressing, subnetting, route summarization, and IP forwarding processes
– Static routing versus dynamic routing protocols, including basics of OSPF and BGP
– VPN services using MPLS (such as VPLS and VPRN) and related service components
– Role and configuration of Nokia 7750 Service Router and command-line interface basics
– Network design considerations for scalability, resilience, and efficient service delivery

The Scalable IP Networks practice tests replicate scenarios such as applying IP subnetting and summarization to a given network design, choosing between routing protocols for particular topologies, configuring basic routing (static and dynamic) for small networks, interpreting forwarding behavior on interfaces, and selecting correct VPN service types for given service requirements. They focus on multiple-choice questions designed to reflect both foundational theory and practical configuration decisions.

By earning the Nokia Scalable IP Networks certification, professionals demonstrate foundational competence in IP network architecture, routing, switching, and VPN services. It supports roles like junior network engineer, IP support technician, and operations or service routing specialist. It can also serve as a stepping stone toward more advanced Nokia-certified tracks (such as Network Routing Specialist I/II) or deeper specialization in routing protocols, service architectures, and complex IP/MPLS deployments. This credential helps increase credibility, opens up career paths in service provider and enterprise networking, and provides a solid base for future growth.
