- D.

- A.
  
  Counting to infinity
- B.

- A.
  
  Holddown
- B.
  
  Full updates
- C.
  
  Split horizon

8.

A router that is using a distance vector protocol just received a routing update that lists a route as having an infinite metric. The previous routing update from that neighbor listed a valid metric. Which of the following is not a normal reaction to this scenario?
- A.
  
  Immediately send a partial update that includes a poison route for the failed route
- B.
  
  Put the route into holddown state
- C.
  
  Suspend split horizon for that route and send a poison reverse route
- D.
  
  Send a full update listing a poison route for the failed route
9.

An internetwork is using a link-state routing protocol. The routers have flooded all LSAs, and the network is stable. Which of the following describes what the routers will do to reflood the LSAs?
- A.
  
  Each router refloods each LSA using a periodic timer that has a time similar to distance vector update timers.
- B.
  
  Each router refloods each LSA using a periodic timer that is much longer than distance vector update timers
- C.
  
  The routers never reflood the LSAs as long as the LSAs do not change.
- D.
  
  The routers reflood all LSAs whenever one LSA changes.
10.

Which of the following is true about how a router using a link-state routing protocol chooses the best route to reach a subnet?
- A.
  
  The router finds the best route in the link-state database.
- B.
  
  The router calculates the best route by running the SPF algorithm against the information in the link-state database.
- C.
  
  The router compares the metrics listed for that subnet in the updates received from each neighbor and picks the best (lowest) metric route.
