Nokia Certified Network Associate (NCNA) — Question 35

Choose two true statements that characterize Link State Routing

Answer options

• A. Routers send a copy of their routing table to their neighbors periodically.
• B. Routers flood link information throughout the entire area.
• C. Network converges quickly (within several seconds) after a topology change.
• D. Routers do not have precise knowledge of the entire network topology.

Correct answer: B, C

Explanation

The correct answers, B and C, are accurate because in Link State Routing, routers do indeed flood link state information throughout the area, and the network converges quickly after changes. Option A is incorrect as routers do not send their entire routing table periodically; instead, they send updates as needed. Option D is also incorrect because routers maintain a complete and precise view of the network topology in Link State Routing.
