Cards in this deck (52)

  1. 1____ routing protocols used since the late 1980s.Dynamic
  2. 2Used to facilitate the exchange of routing information between routers.Routing Protocols
  3. 33 main components of dynamic routing protocolsAlgorithm, Data Structures, and Routing Protocol Messages
  4. 4What command is entered in the router configuration to propagate the static default route in RIP updates?IP default network
  5. 5What router config command is used to prevent the transaction of routing updating through a router interface but still allow that network to be advertised to other routers?Passive-interface
  6. 6In a network configured with RIPv2, how often will a router receive a routing update from a neighbor router?30 seconds
  7. 7What do you call the time it takes for routers to share information, calculate best paths, and update their routing tables?Convergence Time
  8. 8What is the algorithm used by OSPF to calculate the best path to a destination?Dijkstra's

  10. 10What do you call a level 2 route that is a subnet of a classfull network address?Child route
  11. 11What do you call a routing table entry that contains either a next-hop IP address or an exit interface?Ultimate route
  12. 12It refers to the amount of time it takes for routers within the network to froward routing information.Speed of Propagation
  13. 13A network is not completely operable until the network has converged.TRUE
  14. 14Routing protocols typically use tables or databases for its operations. This information is kept in RAMData structures
  15. 15These are used to discover neighboring routers, exchange routing information, and other tasks to learn and maintain accurate information about the network.Routing protocol messages
  16. 16Routing protocols use this for facilitating routing information for best path determination.Algorithm
  17. 17Routing protocols typically use ___ or ___ for its operations.tables and databases
  18. 18Routers do not exchange routing information when there is a topology change.FALSE
  19. 19Part of a router's resources are dedicated for protocol information including CPU time and network link bandwidth.TRUE
  20. 20Networks typically use a combination of both static and dynamic routing.TRUE
  21. 21Routers exchange routing information to learn about ____.Remote networks
  22. 22When a router detects a topology change the routing protocol can advertise thtise this change to other routers.TRUE
  23. 23This refers to booting from a powered off state.Cold start
  24. 24RIP protocols converge quickly than EIGRP and OSPFFALSE
  25. 25Used for routing within an AS. Include RIP, EIGRP, OSPF, and IS-IS.Interior Gateway Protocols (IGP)
  26. 26Used for routing between AS. Official routing protocol used by the internet.Exterior Gateway Protocols (EGP)

  31. 31A router configured with a link-state routing protocol can create a complete view or topology of the network by gathering information from all of the other routers.TRUE
  32. 32A link-state router uses the link-state information to create a topology map and to select the best path to all destination networks in the topology.TRUE
  33. 33Link-state routing protocols use periodic updates. After the network has converged, a link-state update is only sent when there is a change in the topology.FALSE
  34. 34Popular standards based routing protocolOpen Shortest Path First (OSPF)
  35. 35Popular in provider networksIS-IS
