Nokia 4A0-D01 Exam Questions
- 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.
- Topic 4: SR Linux User and System Management: This section of the exam measures skills of a Network Automation Specialist and includes managing user roles, TLS configurations for secure communication, and automation features like Zero-Touch Provisioning (ZTP). It covers ZTP setup, configuration processes, and common issues that may arise during deployment.
- Topic 5: Module 5 – EDA (Event Driven Automation) Introduction This section of the exam measures skills of a Network Automation Specialist and introduces the principles of Event Driven Automation in SR Linux environments. It covers integration with Kubernetes and explores core use cases such as intent-based automation for fabrics and services, as well as enhanced network observability.

Note: Premium Questions for 4A0-D01 were last updated On Jun. 13, 2025 (see below)
Which of the following statements about a CPM-filter policer is FALSE?
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 IP-VRFs in Nokia's SR Linux is FALSE?
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.
Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?
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.
Which of the following statements about Nokia's SR Linux logging is FALSE?
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.
Based on the exhibit output, which of the following statements is TRUE?
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.
