How we research and review these pages
Which of the following statements about using BFD with BGP is FALSE?
Correct Answer:
D
Explanation
BFD helps detect link failures rapidly and notifies BGP to trigger route updates quickly, but it does not speed up the BGP advertisement interval itself. BGP advertisement intervals are controlled by BGP timers, not by BFD.
A static route is configured in two steps in Nokia's SR Linux. Which of the following items CANNOT be configured in the static-routes container?
Correct Answer:
A
Explanation
The static-routes container in Nokia SR Linux does not support configuring a blackhole route directly; it is used to configure destination prefixes, preference values, and next-hop groups for static routing.
Which of the following statements about multi-homing in EVPN is FALSE?
Correct Answer:
C
Explanation
The Ethernet Segment Identifier (ESI) uniquely identifies an Ethernet Segment (ES) globally across the EVPN domain, not just locally for a particular leaf.
Which of the following statements about Zero Touch Provisioning (ZTP) is FALSE?
Correct Answer:
A
Explanation
The ZTP process downloads a provisioning script typically from a defined URL or server, not from a TLS profile. The TLS profile is used for securing communications but does not define the provisioning script location.
Which of the following statements about a CPM-filter policer is FALSE?
Correct Answer:
B
Explanation
The system-cpu-policer in Nokia SR Linux is software-based, not hardware-based. It acts on aggregate control plane traffic and supports hierarchical policing with CPM-filter entries using both distributed and system-cpu-policers.
Which of the following statements about resilient ECMP load balancing is TRUE?
Correct Answer:
D
Explanation
In resilient ECMP load balancing, when a next-hop fails, only the flows that were using that specific next-hop are affected and need to be redistributed, minimizing disruption to other flows.

FAQ
4A0-D01 Exam FAQ
Common questions about the exam itself
What background do I need before taking the 4A0-D01 exam?
Nokia lists no mandatory prerequisites for 4A0-D01, so this exam is designed as a foundation credential. However, familiarity with data center networking concepts, Layer 3 routing, and basic networking protocols like BGP helps you move through the material faster and make practical sense of the SR Linux configuration topics.
How does 4A0-D01 relate to other Nokia data center exams?
4A0-D01 is the entry-level Data Center Fabric exam. After passing it, you can pursue the Nokia Certified Data Center Fabric Network Expert or the Nokia Certified SR Linux Automation Expert certifications by taking follow-up exams like 4A0-D03 that cover advanced topics such as EVPN and data center interconnect.
Which objective area in 4A0-D01 requires the most study time?
SR Linux Configuration and Routing is the largest domain on this exam and where most candidates struggle. This section requires hands-on practice with YANG model-driven CLI, configuration datastores, and routing table verification. Lab time on actual or simulated SR Linux equipment pays off quickly here.
How long should I prepare for the 4A0-D01 exam?
Most candidates with networking experience need four to eight weeks of structured study. If you attend the official Nokia Data Center Fabric Fundamentals course, it typically runs three days and covers all exam topics. Self-study with official materials and practice exams usually takes longer but allows you to move at your own pace.
What happens on exam day for 4A0-D01?
You get 90 minutes to answer 40 multiple-choice questions, either online from home with a proctor or at a Pearson VUE test centre. The total appointment time is 110 minutes, including a 20-minute introductory survey before your testing window starts.
Can I retake the 4A0-D01 exam if I fail?
Yes. Nokia has no waiting period between attempts and no limit on how many times you can retake 4A0-D01. You can reschedule immediately through the Nokia Student Portal.
How much does the 4A0-D01 exam cost?
The exam fee is USD 125 in the United States. Nokia certifications are delivered through Pearson VUE, which may have regional pricing variations, so check with your local Pearson VUE site for exact fees in your country.
What job role matches the 4A0-D01 certification?
This exam leads to the Nokia Certified Data Center Fabric Professional credential. It prepares network engineers and data center architects who design, implement, or support Layer 3 fabric environments using Nokia SR Linux and the 7220/7250 IXR routers.
How long does the 4A0-D01 certification stay valid?
Nokia does not publish an expiration date for this certification on the exam page, so it appears to be a lifetime credential. You should confirm this with Nokia Learning Services, as renewal or recertification policies can change.
Is 4A0-D01 harder than other Nokia routing exams?
4A0-D01 focuses on modern data center architectures with SR Linux, VXLAN, and EVPN rather than traditional service routing protocols like OSPF and BGP. It is considered entry-level in the data center track but requires deeper hands-on lab skills than the older NRS I exam, making it roughly equivalent in difficulty but with different technical content.
