4. What is one advantage of link-state protocols over most distance-vector protocols?

  • ability to route IPX
  • continual route checking with periodic updates
  • faster convergence
  • lower hardware requirements

5. Why do link-state protocols converge faster than most distance vector protocols?

  • Distance vector protocols compute their routing tables before sending any routing update, link-state protocols do not.
  • Link-state protocols have lower computing requirements than distance vector protocols.
  • Link-state protocols send updates out more often than distance vector protocols.
  • Distance vector protocols receive more packets per update than link-state protocols.

6. Refer to the exhibit. If all routers are using a link-state routing protocol, which routers does Router A send hello packets to?

  • B, C
  • B, C, D
  • only the DR
  • only the BR and BDR

7. What information is contained in LSPs sent by link state routers to their neighbors?

  • a copy of the routing table
  • a copy of the topology database
  • the state of directly connected links
  • the most current version of the SPF tree

8. What is one disadvantage of link-state protocols over distance-vector protocols?

  • slow convergence
  • flat network topology
  • periodic updates
  • higher processing requirements

9. After two OSPF routers have exchanged Hello packets and formed an adjacency, what is the next thing to occur?

  • they will take turns broadcasting their entire routing table to each other
  • they will start sending Link-State Packets to each other
  • they negotiate to determine who will be the root router
  • they will adjust their hello timers so they don’t collide with each other

10. How does a router learn about a directly connected network?

  • When the administrator configures a static route.
  • When the administrator configures a dynamic routing protocol.
  • When the administrator assigns an IP address and subnet mask to the interface.
  • When a broadcast address is discovered on a specific interface.
