QUESTION 16:
What are two characteristics of BGP confederations? (Choose two)
A. All routers within the BGP confederation must support BGP confederations.
B. The member AS numbers used with the confederation are visible from outside the
confederation.
C. An Intra-Confederation EBGP session behaves like an EBGP session when
propagating routing updates.
D. Intra-Confederation EBGP neighbors must be directly connected or ebgp-multihop
must be configured.
Answer: A, D
QUESTION 17:
Network topology exhibit.
Why would PassGuide 2 accept or reject the BGP update from PassGuide 13 about the
172.0.0.0/8 prefix?
A. PassGuide 2 will reject BGP update to avoid a potential routing loop.
B. PassGuide 2 will accept the BGP update it is selected as the best path by the BGP route
selection process.
C. PassGuide 2 will reject the BGP update because it already has an OSPF (IGP) route to
reach the 172.0.0.0/8 prefix
D. PassGuide 2 will accept the BGP update and it will be used as a backup path to reach
the 172.0.0.0/8 prefix if the OSPF (IGP) route is not available.
Answer: A
QUESTION 18:
Exhibit
642-691
www.actualtest.org – The Power of Knowing
Neighbor 2.2.2.2 maximum-prefix 1000
What is the purpose of the BGP configuration command in the exhibit?
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: E
QUESTION 19:
Which two statements are true about an EBGP session or an IBGP session? (Choose
two.)
A. IBGP uses AS-Path to detect routing information loops within the AS.
B. EBGP routes have a default Admin Distance of 20 and IBGP routes have a default
Admin Distance of 200.
C. No BGP attributes are changed in EBGP updates except for the next-hop attribute if
next-hop-self is configured.
D. Routes learned from an EBGP peer not advertised to another EBGP peer to prevent
routing information loops.
E. IBGP uses split horizon to prevent routing information loops; routes learned from an
IBGP peer are not advertised to another IBGP peer.
Answer: B, E
