3 / 4
B. The administrative distance
C. The use of AS_PATH attribute

Answer: B
8.What is an advantage of using BFD?
A. BFD is so lightweight that each protocol will generate its own unique BFD session by default, to replace
its own hello messages.
B. BFD built to handle the routing table of the entire Internet, and can safely redistribute it into OSPF.
C. One BFD monitoring session can be used by multiple protocols.
D. BFD is built to handle the routing table of the entire Internet, unlike IGPS.

Answer: C
10.What is the function of the 'Weight' attribute in BGP, and where is it used in the route selection
process?
A. It is used to prioritize routes received from different EBGP peers and is considered before the
AS_PATH attribute.
B. It determines the stability of a route and is checked after the Local Preference attribute.
C. It is a Cisco-specific attribute used to prefer paths from one BGP speaker over another, evaluated
before the Local Preference.
D. It is used to balance load among multiple links and is considered after the MED attribute.
Answer: C
