Number of 4A0-D01 practice questions in our database: 35 (updated: Oct. 21, 2026)
Expected 4A0-D01 Exam Topics, as suggested by Nokia :
  • Topic 1: Nokia DC Fabric Solution: This section of the exam measures skills of a Data Center Network Engineer and covers the architecture and benefits of modern Layer 3 data center networks. It includes an overview of BGP-based routing, VXLAN and EVPN overlays for multi-tenant environments, and key features of the SR Linux operating system. The section also explains how APIs are used for external configuration and introduces the Fabric Services System's management capabilities.
  • Topic 2: SR Linux Configuration and Routing: This section of the exam measures skills of a Network Automation Specialist and focuses on configuring and managing SR Linux systems. It examines the YANG-driven CLI, JSON output, environment variables, and static and dynamic routing. Learners also explore BGP, ECMP, IP-VRF, MAC-VRF, and the use of VXLAN with EVPN to implement both Layer 2 and Layer 3 overlays, including symmetric and asymmetric models.
  • Topic 3: SR Linux Logging, Monitoring, and Filtering: This section of the exam measures skills of a Data Center Network Engineer and addresses how to implement logging, monitoring, and traffic filtering in SR Linux. It explains log file usage, ACL types, CPM filtering, and packet capture filters. Configuration tasks involve applying ACLs and monitoring network activity using capture tools.

User and system management was easy to underestimate, but it cost me time during practice until I learned the key commands and permission patterns, and I still managed to pass the exam. Doing quick reps on users, roles, and session basics helped lock it in.

SR Linux user and system management questions presented broken accounts or failing services and asked which user change or systemctl command resolves the issue. Be comfortable with user account lifecycle, sudoers, SSH key placement and system backups, and I passed after labbing those tasks.

Logging, monitoring, and filtering showed up in ways that tested real troubleshooting habits, and I passed after drilling what to check first when a service breaks. I built a small checklist around telemetry, log levels, and basic filter behavior and reviewed it daily.

Logging and monitoring problems often require interpreting syslog or telemetry samples and choosing correct filters or collection settings. Study syslog levels, journalctl, and basic telemetry formats so you can trace a message back to the config, and I passed after practicing several log troubleshooting exercises.

EDA questions were more conceptual than I expected, and I passed once I could explain event flow and where automation fits operationally. Short scenario style prompts helped most, so I practiced translating a problem statement into what EDA would react to.

EDA introduction questions typically give a small automation goal and ask which event condition and action sequence achieves it. Learn event types, condition matching and action ordering, test flows in a sandbox and I passed once I could sketch rules on paper and validate them.

I passed the Nokia Data Center Fabric Fundamentals exam by focusing on understanding the DC Fabric solution components rather than memorizing terms. The tricky part was mapping concepts to practical deployment choices, so I kept a one page summary of roles and interactions.

SR Linux configuration and routing items frequently show partial configs or route tables and ask which route will be installed or how a packet is forwarded. Get hands on with the CLI, understand policy evaluation order and common show commands, and I passed the exam after drilling those scenarios.

The 4A0-D01 felt very configuration heavy, so running SR Linux labs and getting comfortable with the CLI hierarchy made the difference for me, and I managed to pass on the first try. Pay extra attention to routing basics and how common fabric workflows are expressed in SR Linux.

Topology interpretation questions on the Nokia DC Fabric solution asked me to choose service placement given failure domains and latency constraints. Practice reading fabric diagrams, know spine versus leaf roles and VXLAN EVPN control plane basics, I passed and thank Pass4Success for providing good collection of exam questions for preparation in short time.

The SR Linux logging and filtering section was tricky because it tested subtle filter precedence and matching behavior. Practicing CLI examples and running simulated logs helped me understand the order and troubleshoot faster.

Thi Sato

Selected Answer: **A** Filter precedence in SR Linux follows a top-down evaluation model where the first matching entry wins. Understanding that distinction is what separates candidates who guess on this section from those who answer confidently. A common trap is assuming the most specific match takes priority over position, which is not how SR Linux processes log filters.

Free Nokia 4A0-D01 Exam Actual Questions

Note: Premium Questions for 4A0-D01 were last updated On Oct. 21, 2026 (see below)

Question #1

Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?

Reveal Solution Hide Solution
Correct Answer: A

BGP is not chosen because it is more efficient than link-state protocols; in fact, link-state protocols like IS-IS and OSPF generally provide faster convergence and more efficient route calculation. BGP is used in data centers mainly because it is mature, well understood, supports both IPv4 and IPv6, and offers flexible policy control.


Question #2

Which of the following statements about a CPM-filter policer is FALSE?

Reveal Solution Hide Solution
Correct Answer: B

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.


Question #3

Based on the exhibit output, which of the following statements is TRUE?

Reveal Solution Hide Solution
Correct Answer: B

The exhibit shows ICMP packets being captured and displayed by a tcpdump-like utility, which indicates that a capture-filter is configured to copy ICMP packets to the Control Plane Manager (CPM) where they are processed and monitored.


Question #4

Which of the following statements about IP-VRFs in Nokia's SR Linux is FALSE?

Reveal Solution Hide Solution
Correct Answer: D

Multiple servers connected to the same subnet typically reside within the same Layer 2 domain or MAC-VRF. IP-VRFs operate at Layer 3 and segment routing and forwarding by separate routing tables, so multiple servers on the same subnet are not a function of IP-VRF.


Question #5

Which of the following statements about Nokia's SR Linux logging is FALSE?

Reveal Solution Hide Solution
Correct Answer: B

Nokia SR Linux does not natively support saving logs locally as encrypted files. Logs are managed using standard Linux syslog facilities and can be filtered, but encryption of local log files is not a built-in feature.
