Referring to the topology diagram show in the exhibit,

which three statements are correct regarding the BGP routing updates? (Choose three.)

When a BGP route reflector receives an IBGP update from a non-client IBGP peer, the route
reflector will then forward the IBGP updates to which other router(s)?

Which two BGP mechanisms are used to prevent routing loops when using a design with
redundant route reflectors? (Choose two.)

Which two statements correctly describe the BGP ttl-security feature? (Choose two.)

When implementing source-based remote-triggered black hole filtering, which two
configurations are required on the edge routers that are not the signaling router? (Choose
two.)

Refer to the topology diagram shown in the exhibit and the partial configurations shown
below.

Once the attack from 209.165.201.144/28 to 209.165.202.128/28 has been detected, which
additional configurations are required on the P1 IOS-XR router to implement source-based
remote-triggered black hole filtering?
!
router bgp 123
address-family ipv4 unicast
redistribute static route-policy test

!

In Cisco IOS-XR, the maximum-prefix command, to control the number of prefixes that can
be installed from a BGP neighbor, is configured under which configuration mode?

In Cisco IOS-XR, the ttl-security command is configured under which configuration mode?

Refer to the exhibit.

Given the partial BGP configuration, which configuration correctly completes the Cisco IOSXR route reflector configuration where both the 1.1.1.1 and 2.2.2.2 routers are the clients and
the 3.3.3.3 router is a non-client IBGP peer?

Which three methods can be used to reduce the full-mesh IBGP requirement in a service
provider core network? (Choose three.)
