Pass Nokia IP Networks & Services Fundamentals [4A0-100] Exam: 6 Quality Practice Tests with Explanations (Unofficial)

The “Nokia IP Networks & Services Fundamentals [4A0-100]: 6 Tests” course is your ultimate resource to prepare effectively for Nokia’s foundational IP networking certification exam. Tailored for networking beginners, students, and professionals aspiring to validate their knowledge with Nokia Service Routing Certification (SRC), this course provides six realistic and high-quality practice exams that emulate the style, difficulty, and structure of the official certification exam.

You’ll start with the fundamentals of data networking, including the definition, purpose, and key components of a network such as hosts, switches, routers, and transmission media. You’ll explore different network types like LAN, WAN, and MAN, and the principles of packet-switched networks that are the backbone of modern IP communication.

Next, the course dives deep into the OSI Reference Model, clearly explaining the function of each of the seven layers, their interactions through encapsulation and de-encapsulation, and a comparison with the TCP/IP model to understand how data flows across the network stack.

The Layer 2 – Data Link Layer module covers core concepts such as Ethernet (MAC addresses, frames), VLANs (802.1Q tagging), MAC learning, forwarding, and flooding, along with basic protocols like Spanning Tree Protocol (STP) and Link Aggregation Groups (LAG).

Moving on, the Layer 3 – Network Layer focuses on IPv4 addressing and subnetting, the essentials of IPv6, and routing fundamentals, including differences between static and dynamic routing. You’ll be introduced to widely used routing protocols like RIP, OSPF, and BGP, and how routers forward packets using next-hop logic.

In the Layer 4 – Transport Layer, you'll gain insight into TCP and UDP protocols, port numbers, sockets, and the TCP three-way handshake, along with flow control and congestion avoidance techniques used to maintain efficient and reliable communication.

The IP Addressing & Subnetting section reinforces your understanding of address classes, CIDR notation, binary-decimal conversions, and how to calculate subnets, host ranges, and broadcast addresses. You'll also learn the difference between private and public IPs and the basics of NAT (Network Address Translation).

The course also covers real-world applications in Introduction to Services and Applications, where you will explore services such as DNS, DHCP, HTTP, FTP, and SNMP, and understand the client-server model, along with an introduction to VoIP and streaming technologies.

You will then move into Network Topologies and Architectures, including point-to-point, star, mesh, and hybrid topologies, along with a comparison of enterprise vs. service provider network architectures. A basic overview of MPLS is also included for broader conceptual understanding.

In Basic Network Troubleshooting, you’ll learn how to use tools like ping and traceroute, interpret MAC address and routing tables, and identify issues such as IP conflicts or Layer 2 loops, along with link testing methods.

Security Fundamentals are also addressed, introducing key principles like Authentication, Authorization, and Accounting (AAA), the function of firewalls and ACLs, and how encryption helps secure modern networks.

Finally, the course introduces Nokia-specific concepts, giving a broad understanding of Nokia’s routing platforms like 7750 SR and 7705 SAR, and the fundamentals of service routing, VPRN/VPLS, and Nokia’s Network Services Platform (NSP) – all important from a certification perspective.

Each practice test includes:

• Conceptual and scenario-based questions

• Explanations for correct answers

• Performance-oriented questions covering theory, configuration, and behavior

• Topics aligned strictly with the official exam blueprint

This course doesn’t just prepare you to pass the exam, but helps you build confidence in IP fundamentals, network behavior, troubleshooting, and Nokia-specific architecture.
