Refer to the exhibit. Which two statements are trueabout the partial configuration that is
provided? (Choose two.)

A.
All the configured neighbors are in autonomous system 100.

B.
The peer group shortens the IBGP configuration.

C.
The peer group shortens the EBGP configuration.

D.
Only the outgoing filters are applied to BGP updates.

E.
Three AS-path filters are applied to each BGP neighbor.

Explanation:
This is an IBGP peer group because the AS numbers in “router bgp {AS number}” and
“neighbor internal remote-as {AS number} are the same -> A is correct.
A BGP peer group reduces the load on system resources by allowing the routing table to be
checked only once, and updates to be replicated to all peer group members instead of
being done individually for each peer in the peer group. In addition, a BGP peer group also
simplifies the BGP configuration -> B is correct.
This is the process of creating a peer-group (used the output above):

Just one thing to notice is the last command “neighbor 171.69.232.55 filter-list 3 in”
indicates the filter-list 3 will be applied for neighbor 171.69.232.55 while other neighbors will
be applied filter-list 2 as the inbound filter-list(all neighbors use outbound filter-list 1).
