Nokia 4A0-C04 Exam Questions

Exam Name: Nokia NRS II Composite Exam: OSPF version Exam
Exam Code: 4A0-C04
Related Certification(s): Nokia Network Routing Specialist II Certification
Certification Provider: Nokia
Number of 4A0-C04 practice questions in our database: 298 (updated: Oct. 16, 2026)
Expected 4A0-C04 Exam Topics, as suggested by Nokia :
  • Topic 1: Nokia OSPF Routing Protocol: For network engineers and administrators working with Nokia systems, this section of the exam covers the fundamentals of OSPF (Open Shortest Path First) routing protocol. It likely includes topics such as OSPF operation, area types, LSA types, and OSPF configuration on Nokia routers.
  • Topic 2: Nokia Border Gateway Protocol Fundamentals for Services: For network architects and service providers using Nokia equipment, this domain focuses on BGP (Border Gateway Protocol) and its application in service environments. It probably covers BGP basics, route reflection, BGP communities, and service-specific BGP implementations on Nokia platforms.
  • Topic 3: Nokia Multiprotocol Label Switching: For network engineers and designers working with Nokia MPLS solutions, this part of the exam delves into MPLS technology. It likely includes MPLS fundamentals, Label Distribution Protocol (LDP), MPLS Traffic Engineering, and MPLS VPN configurations on Nokia devices
  • Topic 4: . Nokia Services Architecture: For service architects and network designers utilizing Nokia's service-oriented solutions, this section covers Nokia's approach to service architecture. It probably encompasses topics like service types, Quality of Service (QoS) implementations, and service deployment strategies on Nokia platforms.

Time management mattered more than difficulty, since a few questions were wordy and easy to overthink, so I did timed practice sets and passed the 4A0 C04 without needing a retake.

Expect BGP policy and community problems that give a set of policy rules and ask which prefixes will be exported or preferred, those are subtle because order and implicit defaults matter. Practice writing and reading route-maps, community tagging, and how policies interact with route selection to be fast on these. Someone I know cleared the exam and recommended focusing on policy test cases rather than only memorizing attribute definitions.

MPLS was the trickiest section for me because the questions leaned on practical forwarding concepts, so I focused on label operations and common troubleshooting steps and I managed to pass.

Service architecture questions tested how services map onto network constructs and enforce SLAs, sometimes with multi-device configuration snippets you must interpret. Review service models, orchestration concepts, VNFs, and how QoS and traffic steering tie into underlying protocols. I managed to pass the exam and thanks Pass4Success for providing good collection of exam questions for preparation in short time.

BGP fundamentals showed up in subtle ways, like next hop handling and policy impacts alongside OSPF, so I used small lab scenarios to test my assumptions and that helped me pass the exam.

MPLS items often presented a packet flow and required you to state label operations at each hop or choose the right LSP setup mechanism. Drill label stack semantics, difference between LDP and RSVP-TE, and how penultimate hop popping affects forwarding. A peer who sat the test passed and said targeted configuration exercises saved a lot of time.

Many questions on BGP neighbor behavior were scenario based, asking you to find why a session would stay in Active or not install received prefixes. Focus on BGP finite state machine, TCP handshake issues, neighbor authentication, and basic attributes like local-pref and AS_PATH for troubleshooting. I passed the Nokia NRS II exam and found practice labbing sessions crucial.

The 4A0 C04 felt heavier on OSPF behaviors than I expected, especially LSA types and area design, so I drilled show outputs until I could read them quickly and I passed on the first try.

I had to work through several OSPF area design and LSA type questions where the exam gave a topology and asked which LSA would carry redistributed external routes, those tricked me until I reviewed LSA types and redistribution nuances. Study area types, stub and NSSA behaviors, and how ASBRs advertise external routes. A colleague experienced the same exam, managed to pass, and thanks Pass4Success for providing good collection of exam questions for preparation in short time.
