1.1.7 Check Your Understanding – OSPF Features and Characteristics Answers

1. Which of the following OSPF components is associated with the neighbor table?

  • Dijkstra’s algorithm
  • Link-State database
  • Routing protocol messages
  • Adjacency database
  • Forwarding database

Explanation: The adjacency database is responsible for creating the neighbor table.

2. Which of the following OSPF components is responsible for computing the cost of each route?

  • Dijkstra’s algorithm
  • Link-State database
  • Routing protocol messages
  • Adjacency database
  • Forwarding database

Explanation: The Dijkstra algorithm is responsible for computing the cost for each route.

3. Which of the following OSPF components is associated with the topology table?

  • Dijkstra’s algorithm
  • Link-State database
  • Routing protocol messages
  • Adjacency database
  • Forwarding database

Explanation: The Link-state database is responsible for creating the topology table.

4. Which of the following OSPF components is associated with the routing table?

  • Dijkstra’s algorithm
  • Link-State database
  • Routing protocol messages
  • Adjacency database
  • Forwarding database

Explanation: The Forwarding database is responsible for creating the routing table.
