Nokia IS-IS Routing Protocol

No. This is independent study material written for candidates searching for the credential. It is not affiliated with, endorsed by, or approved by Nokia, and it does not reproduce official exam content. Always confirm exam scope, scheduling, and pricing with Nokia's own training pages before you register.

The published source does not list an exam blueprint. Based on the certification title, expect IS-IS fundamentals: adjacency formation, level-1 and level-2 operation, areas, link-state database synchronisation, SPF computation, TLVs, IPv4 and IPv6 support, metrics, and troubleshooting. Verify the real scope with Nokia Learning.

Unknown. The source page provides no question count, no duration, no passing score, and no fee. Any specific numbers you see elsewhere should be treated as unverified. Ask Nokia directly, or check the current certification page, because exam logistics are revised periodically.

It suits network engineers, design and operations staff, and service-provider transport specialists who already work with IP routing and want to demonstrate depth in IS-IS, particularly in Nokia service router environments. Candidates with only entry-level routing knowledge should build OSPF and general link-state fundamentals first.

Start with link-state theory and IS-IS packet types, then adjacency formation and hello timers, then levels, areas, and the two-level database. Move on to SPF, metrics, and TLVs, then IPv6 and traffic engineering extensions. Finish with troubleshooting drills and packet-capture analysis before attempting practice questions.

Treat it as an intermediate-to-advanced routing exam. IS-IS is conceptually compact but operationally subtle: level boundaries, ATT bits, database synchronisation, and metric styles trip up candidates who only memorised theory. Hands-on lab time matters more than reading, because most difficulty comes from interpreting real adjacency and database states.

The source does not state a retake policy or a validity period, so neither can be confirmed here. Ask Nokia Learning about retake rules, waiting periods, and recertification requirements before you book, and record the answer, since these policies change between exam revisions.

Common failure modes are confusing level-1 and level-2 behaviour, misunderstanding how areas and level boundaries interact, misreading adjacency states during troubleshooting, and weak grasp of TLV encoding. Candidates who never capture and inspect real IS-IS packets usually struggle with the diagnostic-style questions.

Pair the relevant Nokia training offer with a lab topology of at least four routers across two areas. Deliberately break adjacencies, change metrics, and observe database and routing-table changes. Practise reading LSP and SNP captures, and explain each field aloud. That habit transfers directly to scenario-style exam questions.

Use Nokia's own training and certification pages and its Learning at Nokia resources. The public certification page currently confirms only that Nokia runs industry-recognized certification programs; it publishes no exam logistics. Confirm format, cost, scheduling, and policy there rather than relying on third-party summaries.
