Which Layer 4 protocol does EIGRP use to provide
reliability for the transmission of routing information?
DUAL
IP
PDM
RTP
TCP
UDP
2
Which of the following statements 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 information.
The updates are sent to all routers
in the routing table.
Updates are bounded by the routers
in the topology table.
3
What is the EIGRP term for a backup route?
backup route
default route
feasible successor route
gateway
secondary route
successor
route
4
Why would it be necessary to configure the bandwidth
setting on an EIGRP interface rather than leaving it at the default
setting? (Choose two.)
A suboptimal route may be chosen as
the best path to a destination if the bandwidth setting is higher
than the actual bandwidth of the link.
The network may be unable to
converge if the bandwidth setting does not match 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.
5
If an EIGRP route goes down and a feasible successor
is not found in the topology table, how does DUAL flag the route
that has failed?
recomputed
passive
active
down
unreachable

path
8
Which of the following are found in the EIGRP neighbor
table? (Choose two.)

9
Which of the following router commands is recommended
only for troubleshooting specific types of network problems, not for
monitoring normal network operation?

monitor
10

11
What is the default administrative distance of EIGRP
internal routes?
70
90
100
110
120

12
What is the advantage of routers forming adjacencies
when using EIGRP? (Choose three.)
Neighbor routers can quickly take
over for a router that is in passive mode.
New routers and their routes can
quickly be discovered by neighbor routers.
A router can share routing loads
with neighbor routers.
A router can quickly discover when
a neighbor router is no longer available.
Changes in network topology can
quickly be shared with neighbor routers.
Neighbor routers can save overhead
by sharing their DUAL databases.

Which of the following types of routes will be denoted
by EX in EIGRP routing table entries? (Choose two.)

non-adjacent EIGRP routers
any route with a hop count metric
higher than 224
EIGRP routes that originate in
different autonomous systems
all passive routes in the routing
table

17
What information is maintained in the EIGRP topology
database for a destination route? (Choose three.)
the routing protocol

route
the highest cost of the route
the SRTT value for the route
the route cost as advertised by the
neighboring router
