Zorluk: OrtaRouting Concepts and Dynamic Routing Protocols

When evaluating dynamic routing protocol operations within an enterprise network, which of the following operational characteristics accurately distinguish link-state routing protocols from distance-vector routing protocols? (Select TWO)

  1. Link-state protocols build a complete, synchronized topology database of the network area and run the Shortest Path First algorithm to calculate optimal routes.Cevap
  2. B
    Link-state protocols periodically broadcast their entire routing table to directly connected neighbors at fixed time intervals.
  3. Link-state protocols send multicast event-triggered updates only when a link state or network topology change is detected.Cevap
  4. D
    Link-state protocols rely on static address translation overload and split-horizon timers to control autonomous system boundaries.

Cevap

Link-state dynamic routing protocols maintain a synchronized topology database calculated via the Shortest Path First algorithm and flood incremental update notifications only when network state changes occur.
Link-state dynamic routing protocols operate by maintaining a complete map of the entire network topology in a synchronized database. Each router uses Dijkstra's Shortest Path First algorithm to build its routing table independently. Additionally, link-state protocols conserve bandwidth and speed up convergence by sending multicast updates only when network changes take place.

Adım Adım Çözüm

1
Identify the key operational mechanisms of link-state dynamic routing protocols.
Link-state protocols (such as OSPF and IS-IS) collect Link-State Advertisements to form a complete Link-State Database (LSDB) representing all routers and links in an area.
This global topology awareness allows each router to independently execute Dijkstra's Shortest Path First (SPF) algorithm.
2
Analyze how link-state protocols handle network updates compared to distance-vector protocols.
Link-state routers exchange incremental multicast updates only when a topology change occurs, avoiding unnecessary periodic full-table updates.
Event-driven incremental updates reduce bandwidth consumption and accelerate convergence across large networks.
