Which of the following statements about the EVPN Layer 2 Attributes extended community is FALSE?
Correct Answer:
B
In the exhibit, the EVPN-IRB is using the interface-ful unnumbered model and is fully operational. Which of the following statements is FALSE?
Correct Answer:
C
Based upon the exhibit, which of the following statements is FALSE?
Correct Answer:
A
Explanation
VPLS 10 does not need to be configured with two BGP instances on PE3 and PE4. VPLS 10 can be configured with a single BGP instance that supports both VXLAN and MPLS encapsulations.
In the exhibit, VPWS 4 enables communications between CEI and CE2. Which of the following statements regarding the operation of VPWS 4 is FALSE?
Correct Answer:
C
An operator configures an EVPN-IRB that uses the interface-ful unnumbered forwarding model on a Nokia 7750 service router. Which of the following statements regarding the configuration performed on each participating PE is FALSE?
Correct Answer:
C
In the exhibit, PE2 is receiving an EVPN auto-discovery (A-D) route from PEI. Based on the output, which of the following statements is FALSE?
Correct Answer:
D
Explanation
This route indicates that the EVPN service is configured on PE1 with a service MTU of 1500, not 1514. The service MTU is indicated by the MPLS label value in hexadecimal format. The MPLS label value of 0x05DC corresponds to a decimal value of 1500.
Which of the following statements about the EVPN route types used to support multi-homing is TRUE?
Correct Answer:
A

Domain 1: Module 1 - Introduction to EVPN
Learn basic EVPN concepts and how the technology uses control plane and data plane mechanisms to support multiple service types. This module covers EVPN operation across Layer 2 services, Layer 3 routing, and data center interconnect scenarios, establishing the foundation for all subsequent EVPN architectures.
Domain 2: Module 2 – EVPN for ELAN services
Master EVPN VPLS configuration with MPLS and VXLAN encapsulation, including route type handling and flooding list management. Learn how EVPN MAC routes and IMET routes enable bridge forwarding table population and inter-domain VPLS interconnection across different encapsulation methods.
Sample questions from this domain above:
Q1Q3
Domain 3: Module 3 – EVPN for Layer-3 services
Understand EVPN integrated routing and bridging (IRB) architecture and the four distinct interface models for Layer-3 forwarding. Discover how asymmetric and symmetric forwarding approaches use different EVPN route types to populate routing tables and manage inter-subnet traffic.
Sample questions from this domain above:
Q2Q5
Domain 4: Module 4 – Multi-Homing in EVPN
Study Ethernet Segment definition and the designated forwarder election algorithms that control traffic distribution across multi-homed links. Learn how split-horizon and aliasing mechanisms prevent loops while enabling load-balancing in single-active and all-active redundancy modes.
Sample questions from this domain above:
Q6Q7
Domain 5: Module 5 – EVPN for ELINE services
Configure EVPN virtual private wire service (VPWS) with single-homing and multi-homing topologies. Examine the role of attachment circuits and EVPN route types in enabling point-to-point connectivity with redundancy options.
Sample question from this domain above:
Q4
Domain 6: Module 6 – EVPN and traditional MPLS services
Enable connectivity between EVPN and non-EVPN network segments for VPWS, VPLS, and IRB services. Learn interoperability patterns that let legacy MPLS services coexist with EVPN-enabled domains across multi-site deployments.
FAQ
4A0-115 Exam FAQ
Common questions about the exam itself
What background do I need before attempting the 4A0-115 exam?
Nokia lists no mandatory prerequisites for 4A0-115. However, you should have practical experience with MPLS networking, routing, and Layer 2 switching concepts, since the exam tests advanced EVPN deployment scenarios. Most candidates have worked with traditional VPN technologies before moving to EVPN.
How long should I spend preparing for the 4A0-115 exam?
Preparation time varies with your background, but expect 6 to 12 weeks of structured study if you are new to EVPN. If you have attended the Nokia Ethernet Virtual Private Network Services course, you may be ready in 2 to 4 weeks of focused review. Hands-on lab time accelerates learning significantly.
Which module in 4A0-115 is considered the most difficult?
Module 3 on EVPN for Layer-3 services and Module 4 on multi-homing cause the most difficulty for candidates. These cover the complex interface models, designated forwarder election algorithms, and split-horizon mechanisms that require both conceptual understanding and configuration practice.
What exactly happens on exam day for the 4A0-115 test?
Your exam appointment lasts 110 minutes total. The first 20 minutes are an introductory survey, leaving you 90 minutes to answer 40 questions. The test is delivered online with proctoring or at an authorized test centre. You must present valid identification and follow the proctor's instructions on camera setup and desk environment.
Can I retake the 4A0-115 exam if I fail?
Nokia does not publicly specify retake rules or waiting periods for 4A0-115 on their official exam page. You should contact Nokia or your exam delivery provider to confirm retake availability and any time requirements between attempts.
How long is my Nokia Service Routing Architect certification valid after passing 4A0-115?
Nokia does not publish a validity period or renewal requirement for the certification earned by passing 4A0-115 on their official exam page. Contact Nokia training directly for details on how long your certification remains active.
Which job role does the 4A0-115 certification best prepare me for?
The exam targets network engineers and architects designing, deploying, and managing EVPN services in service provider and enterprise environments. It suits roles such as service routing architect, network design engineer, or MPLS/EVPN deployment specialist.
How does 4A0-115 relate to other Nokia Service Routing Architect exams?
4A0-115 is one exam path toward the Nokia Service Routing Architect certification. Other exams in the track cover routing protocols, segment routing, and traditional VPN services. Check Nokia's certification roadmap to see which exams align with your career goals.
What format are the 4A0-115 exam questions?
The 40 questions are multiple-choice format delivered online or at a test centre. The exam tests practical understanding of EVPN concepts and configuration scenarios rather than pure memorization.
Can I take the 4A0-115 exam in languages other than English?
No. Nokia publishes English as the only language available for the 4A0-115 exam. If you need exam accommodation for language or other accessibility reasons, contact Nokia training support.
