Zorluk: KolayRouting Concepts and Dynamic Routing Protocols

A network administrator needs to implement an interior gateway protocol (IGP) that uses a link-state routing algorithm to maintain a complete map of the network topology. Which of the following protocols should the administrator deploy?

  1. Open Shortest Path First (OSPF)Cevap
  2. B
    Routing Information Protocol (RIP)
  3. C
    Port Address Translation (PAT)
  4. D
    Address Resolution Protocol (ARP)

Cevap

Open Shortest Path First (OSPF)
Open Shortest Path First (OSPF) is an interior gateway link-state routing protocol. Each router running OSPF maintains a Link-State Database (LSDB) containing a complete topology map of the network area to compute the shortest path to every destination subnet.

Adım Adım Çözüm

1
Identify the protocol class specified in the requirement
The scenario requires an interior gateway protocol operating on a link-state algorithm to maintain a complete topology map.
Link-state protocols construct a complete view of the network topology to compute shortest paths.
2
Evaluate the candidate options against link-state protocol characteristics
OSPF uses Dijkstra's Shortest Path First algorithm and Link-State Advertisements to map the entire network area.
OSPF is the standard link-state dynamic routing protocol among the choices provided.
