  1. 1. Question
    Which dynamic routing protocol was developed as an exterior gateway protocol to interconnect different Internet providers?
  2. 2. Question
    In the context of routing protocols, what is a definition for time to convergence?
    •  the capability to transport data, video, and voice over the same media
  3. 3. Question
    An OSPF enabled router is processing learned routes to select best paths to reach a destination network. What is the OSPF algorithm evaluating as the metric?
    •  The cumulative bandwidth that is used along the routing path.
  4. 4. Question
    What is the difference between interior and exterior routing protocols?
    •  Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.
  5. 5. Question
    What are two purposes of dynamic routing protocols? (Choose two.)
    •  discover remote networks
    •  select best path to destination networks

    Which routing protocol sends a routing update to neighboring routers every 30 seconds?
  10. 10. Question

    •  R1, R3, R5, R7
  15. 15. Question
    What are two features of the OSPF routing protocol? (Choose two.)
    •  calculates its metric using bandwidth
    •  uses Dijkstra’s algorithm to build the SPF tree
  16. 16. Question
    Which two protocols are link-state routing protocols? (Choose two.)
    •  IS-IS
  17. 17. Question
    Which routing protocol uses link-state information to build a map of the topology for computing the best path to each destination network?
  18. 18. Question
    Which two requirements are necessary before a router configured with a link-state routing protocol can build and send its link-state packets? (Choose two.)
    •  The router has determined the costs associated with its active links.
    •  The router has established its adjacencies.
  19. 19. Question
    What happens when two link-state routers stop receiving hello packets from neighbors?
    •  They consider the neighbor to be unreachable and the adjacency is broken.
  20. 20. Question
    Which two events will trigger the sending of a link-state packet by a link-state routing protocol? (Choose two.)
    •  a change in the topology
    •  the initial startup of the routing protocol process
  21. 21. Question
    What is the first step taken by a newly configured OSPF router in the process of reaching a state of convergence?
    •  It learns about directly connected links in an active state.
  22. 22. Question
    Which two components of an LSP enable an OSPF router to determine if the LSP that is received contains newer information than what is in the current OSPF router link-state database? (Choose two.)
    •  sequence numbers
    •  aging information
  23. 23. Question
    Which statement is an incorrect description of the OSPF protocol?
    •  When compared with distance vector routing protocols, OSPF utilizes less memory and less CPU processing power.
  24. 24. Question
    What is a disadvantage of deploying OSPF in a large single area routing environment?
    •  OSPF uses excessive LSP flooding.
  25. 25. Question
