About 4A0-115 Exam
Overview of Nokia 4A0-115 Exam and Its Relevance in 2025
The Nokia 4A0-115 exam targets professionals working with Ethernet Virtual Private Network (EVPN) services in service provider and enterprise networks. It’s a part of Nokia’s advanced Service Routing Certification path, meant for those who handle complex IP/MPLS infrastructure and EVPN deployments. This is not a beginner-level test, and it’s structured in a way that assumes the candidate already has solid knowledge of Layer 2 and Layer 3 networking concepts.
What makes this exam important in 2025 is how relevant EVPN technology has become. As enterprise and cloud networks keep growing, the need for virtualized services, dynamic multi-tenant environments, and better network segmentation is increasing. This certification acknowledges engineers who understand how to implement VXLAN, MP-BGP, and other advanced EVPN constructs across multi-domain setups. If you’re serious about network engineering, particularly in telecom or ISP roles, this cert is going to carry weight.
It’s designed for engineers already hands-on with routers and switches, especially those working with Nokia equipment in production-grade topologies. The 4A0-115 lets hiring managers know you’re past the basics and into solving actual network isolation and scaling issues.
Nokia’s Certification Track Is Built Around Practical Skills
Nokia has kept its Service Routing Certification (SRC) path clear of unnecessary filler. Unlike many programs that stay high-level, Nokia’s exams, especially the 4A0-115, are deeply technical. They’re aimed at folks who actually build and maintain networks not just talk about them in theory.
The SRC track has different levels, but this exam sits at a point where it filters serious candidates from casual learners. It’s the sort of certification that builds credibility fast, especially in service provider environments where mistakes are expensive.
What Makes the 4A0-115 a Popular Option in Advanced Networking
One of the reasons this cert gets attention is because it covers EVPN from multiple angles MPLS, VXLAN, MAC learning, BGP signaling, and inter-subnet routing. That makes it useful for more than just one kind of network. Whether you’re in the data center space or working in a WAN-heavy service provider setup, the concepts stick.
In most real deployments, EVPN is about redundancy, load balancing, and layer separation. All of these are covered directly in the certification, which gives it real value beyond just passing a test.
Who Should Be Taking the 4A0-115 Certification Exam
If you’re still learning what a BGP neighbor is, this isn’t your test yet. But if you’ve worked with MPLS, used BGP-LU, set up VXLAN overlays, or even done IPSec tunnels, this is probably where you want to be.
The exam is popular among:
- Service provider engineers
- Core network architects
- Datacenter routing engineers
- Backbone support leads
- Nokia hardware operators
It’s also ideal if you’ve already passed exams like 4A0-101 or 4A0-104 and want to move toward SRA level certification.
What 4A0-115 Actually Teaches You to Handle
The knowledge gained isn’t just about answering questions. It translates into solving real problems in real networks. Some of the skills you’ll sharpen through this exam include:
- EVPN route types (RT-2, RT-5, etc.)
- MAC learning over BGP
- VLAN-aware and VLAN-based services
- Integrated Routing and Bridging (IRB)
- Redundant link deployment and convergence behavior
- Control plane convergence in EVPN environments
This isn’t surface-level stuff. These skills are the backbone of any dynamic and resilient EVPN architecture.
How Difficult Is the 4A0-115 in Practice
Most test-takers agree the exam is difficult but fair. If you’ve worked on actual network deployments or have labbed the scenarios yourself, you’ll recognize the patterns in many questions. But if your experience is mostly theory or vendor-agnostic books, the exam might feel dense.
What makes it tough is that it doesn’t focus on trick questions. Instead, it presents accurate but layered scenarios, where you have to recall details like BGP route behavior or EVPN failover reactions.
Salary Potential After Getting Certified
Professionals with the 4A0-115 under their belt often land jobs that pay better than standard network support roles. The average salary for certified engineers ranges between $95,000 to $130,000 annually, especially when working with large ISPs, global enterprise networks, or telecom vendors.
This boost isn’t just about the cert itself. It comes from the combination of vendor-specific skills and real-world deployable knowledge that employers know takes time to master.
Where It Fits in Your Career Timeline
This exam often acts as a pivot point in a networking career. Many engineers use it as a transition step from mid-level routing work into more senior positions like:
- Network design lead
- Datacenter solutions engineer
- Service architect
If you’re planning to go for Nokia’s SRA-level credentials, the 4A0-115 is one of those certs you’ll need to complete anyway. But even if you stop at this point, it stands strong on its own.
How the 4A0-115 Exam Is Structured and Delivered
The Nokia 4A0-115 exam sticks to a technical format without adding unnecessary gimmicks. Its layout is clean, straightforward, and built for those who’ve taken the time to learn the material.
Breakdown of the Exam Format

The scenario-based questions are typically where most candidates slow down. These simulate real-world issues that you’ll have to think through before selecting a solution.
The Key Focus Areas in the 4A0-115 Exam
The 4A0-115 exam doesn’t drift off into unrelated topics. It stays focused on EVPN and supporting network behaviors, including the integration of different Layer 2/Layer 3 technologies.
You’ll Be Expected to Know:
- The operation of EVPN signaling using MP-BGP
- Methods for MAC learning, including control plane learning
- Use cases for VLAN-aware vs VLAN-based services
- IRB (Integrated Routing and Bridging) configuration and design
- Handling of MAC mobility and loop protection
- Scenarios involving multi-homing and redundancy
Each of these shows up not just as isolated facts but as part of scenario-based questions. This format tests your applied knowledge, not just memory.
Understanding How the Exam Flows
It’s not a time-waster kind of test. The 90 minutes are enough for someone prepared but tight for someone who isn’t. There’s a balance of quick factual recall and multi-step scenario solving.
- Simple recall questions: Know your route types and VLAN modes
- Scenario items: These demand deeper thought and often combine multiple concepts
A lot of candidates find the second half of the exam heavier, which usually includes the more scenario-heavy items.
Practical Tips That Actually Help
There’s no point in brute-forcing your prep. Here’s what works best for this exam:
- Spend time on Nokia whitepapers and EVPN-focused documentation
- Use GNS3 or similar emulators to simulate EVPN topologies
- Go over IRB routing logic repeatedly until it feels natural
- Create tables or visual maps of route propagation paths
- Join Nokia networking forums to discuss common exam patterns
Pay Attention to These High-Yield Topics
Some sections always get more attention in the test. Focusing on them gives you a better shot at scoring well.
Frequently Targeted Concepts:
- RT-2 vs RT-5 route behavior
- Differences between control plane vs data plane learning
- MAC duplication and loop prevention techniques
- BGP route propagation between EVPN instances
- VLAN assignment methods in multi-tenant environments
If you don’t fully understand how these pieces work in tandem, you’re more likely to trip up, especially in longer scenario questions.
