Why would it be necessary to configure the bandwidth setting on an EIGRP interface rather than leaving it at the default sett
ing?
(Choose two.)


A suboptimal route may be chosen as the best path to a destination if the bandwidth setting is higher than the actual bandwid
th of
the link.


The network may be unable to converge if the bandwidth setting does not ma
tch the actual bandwidth of the link.


Routing updates might arrive too fast for the interface to handle and be discarded because of buffer overflow.


The configured bandwidth
must match the actual speed of the link so the link will operate properly.


Setting the bandwidth to a higher rate will optimize the effective throughput of the link.

3

Which of the following state
ments describes the bounded updates used by EIGRP?


Bounded updates are sent to all routers within an autonomous system.


Partial updates are sent only to routers that need the inf
ormation.


The updates are sent to all routers in the routing table.


Updates are bounded by the routers in the topology table.

7

Which of the following statements are true of routers that are running EIGRP? (Choose three.)
