Answer:
Q NO. 3 The purpose of the bgp
always-comprate-med command is to compare the MED ______.
A. Even if the
routes originate in different ASs.
B. Even if the
routes originate from the same AS.
C. Even if the
routes have different AS-Path length.
D. Last, after
all other path attributes are compared.
E. First,
before any other path attributes are compared.
Answer:
Q NO. 4 Which three statements are true about route reflectors?
(Choose three)
A If the
route is learned from an EBGP peer by the route reflector, it is
redistributed to all IBGP and EBGP peers.
B If the
route is learned from a non-client IBGP peer by the route reflector,
it is reflected to all EBGP peers only.
C If the
route is learned from a non-client IBGP peer by the route reflector,
it is reflected to EBGP peers and clients only.
D. If the
route is learned from a client IBGP peer by the route reflector, it
is reflected to all clients only, except the originating client.
E. If the
route is learned from a client IBGP peer by the route reflector, it
is reflected to all EBGP peers, nonclients, and clients (except the
originating client).
Answer:
Q NO. 5 Given the following:
router bgp 65123 neighbor customers peer-group neighbor 10.1.1.2
remote-as 65213 neighbor 10.1.1.2
peergroup customers neighbor 10.2.2.2 remote-as 65314 neighbor
10.2.2.2 peer-group customers neighbor
10.2.2.2 route-map test2 in
Based on the BGP configuration for a router in AS 65123, which two
statements are true? (Choose two)
A. The peer
group is named "customers".
B. The two
EBGP peer belongs to the same peer-group.
C. The
route-map named "test2" will be applied both EBGP peers.
D. The peer
group configuration is used to reduce the full mesh BGP
requirements.
E. AS 65123,
AS 65314 and AS 65213 belong to the same BGP confederation named
"customers".
Answer:
Q NO. 6 A Transit AS contains 10
routers. To enable full mesh IBGP within that Transit AS, how many
IBGP sessions are required?
A. 10
B. 28
C. 45
D. 50
E. 100
Answer:
Q NO. 7 What is the purpose of
the following BGP configuration command?
neighbor 2.2.2.2 maximum-prefix 1000
A It
limits the number of prefixes that can be sent to neighbor 2.2.2.2
to 1000.
B It
limits the number of prefixes that can be sent to and received from
the 2.2.2.2 neighbor to 1000.
C. If the
number of prefixes sent to the 2.2.2.2 neighbor exceeds 650, the
router starts to generate a warning message.
D If the
number of prefixes received from the 2.2.2.2 neighbor exceeds 650,
the router starts to generate a warning message.
E. If the
number of prefixes received from the 2.2.2.2 neighbor exceeds 1000,
the neighbor relationship to 2.2.2.2 will be dropped.
Answer:
Q NO. 8 What are the two methods
for configuring BGP route dampening? (Choose two)

neighbor ip-address maximum prefix command.
D. Using the
neighbor ip-address unsuppress-map command.
