  • Question 44:

    Each router (RTA, RTB, and RTC) has one iBGP adjacency with the route reflector router RTD. Router RTC has an iBGP route advertised by RTA, but the same route is missing from RTB. The network engineer verifies that route filtering does not deny the route advertisement. Which action corrects the problem?

    A. RTD(config-router)#neighbor 192.168.1.1 route-reflector-client RTD(config-router)#neighbor 192.168.1.1 description RTA RTD(config-router)#neighbor 192.168.1.2 route-reflector-client RTD(config-router)#neighbor 192.168.1.2 description RTB
    B. RTC(config-router)#neighbor 192.168.1.4 route-reflector-client RTC(config-router)#neighbor 192.168.1.4 description RTD
    C. RTA(config-router)#neighbor 192.168.1.4 route-reflector-client RTA(config-router)#neighbor 192.168.1.4 description RTD RTB(config-router)#neighbor 192.168.1.4 route-reflector-client RTB(config-router)#neighbor 192.168.1.4 description RTD
    D. RTB(config-router)#neighbor 192.168.1.3 route-reflector-client RTB(config-router)#neighbor 192.168.1.3 description RTC
    E. RTB(config-router)#neighbor 192.168.1.3 route-reflector-client RTB(config-router)#bgp cluster-id 192.168.1.2 RTB(config-router)#no bgp client-to-client reflection

  • Question 45:

    What is one of the configuration errors within an AS that can stop a Cisco IOS-XR router from announcing certain prefixes to its EBGP peers?

    A. Some prefixes were mistagged with the no-export BGP community
    B. Some prefixes were set with an MED of 0
    C. The outbound BGP route policy only has set actions defined without any pass actions defined
    D. The inbound BGP route policy only has set actions defined without any pass actions defined

  • Question 46:

    Which three statements regarding the BGP operations are correct? (Choose three)

    B. PE5 is using the IS-IS route to reach the BGP next-hop for the 172.16.66.0/24 prefix
    C. PE5 has BGP route dampening enabled
    D. The BGP session between PE5 and P1 is established using the loopback interface and next- hop-self
    E. The BGP session between PE5 and CE5 is established using the loopback interface
