A-) STP

B-) RIP

C-) CDP

D-) 802.1q

What would the next hop IP address be for this packet?

A-) 192.168.1.10

B-) 192.168.4.2

C-) 192.168.10.254

D-) None; the packet will be dropped.

13-) Which cable can suffer attenuation if it is bent beyond the minimum bend radius?

A-) UTP

B-) STP

B-) show spanning tree

C-) show vlan spantree

D-) show spanning-tree vlan

E-) show spanning-tree interface

16-) Which of the following statements describes split horizon?

A-) The router learns from its neighbor that a route has gone down, and the router sends an update back to the neighbor with an infinite metric to that route.

B-) For a period of time, the router will ignore any route advertisements with a lower metric to a downed route.

C-) A router will not send route information back out the same interface over which it was learned.

D-) The moment a router determines a route has gone down, it will immediately send a route update with an infinite metric to that route.

E-) The packets are flooded when a topology change occurs, causing network routers to update their topological databases and recalculate routes.
