A network engineer implements OSPF on the network and then notices frequent faults in traffic between two routers, particularly on interface TenGigE 0/0/0/1. The engineer decides to configure NetFlow to monitor the issue. Which configuration must the engineer apply to the router?

• A.interface tenGigE 0/0/0/1
  ip flow egress
  snmp-server community public
  snmp-server enable traps isdn
  snmp-server host 192.168.1.27 version 2c public
• B.ip flow-export destination 192.168.2.1 2055
  ip flow-export source loopback0
  ip flow-export version 9
  ip flow-cache timeout active 1
  ip flow-cache timeout inactive 15
  snmp-server ifindex
  persist interface tenGigE 0/0/0/1
  ip flow ingress
• C.interface tenGigE 0/0/0/1
  ip flow ingress
  ip flow-export version 9
  ip flow-cache timeout active 1
• D.ip flow-export destination 192.168.2.1 2055
  ip flow-export source loopback0
  ip flow-export version 9
  ip flow-cache timeout active 1
  ip flow-cache timeout inactive 15
  snmp-server ifindex persist

Based on the show/ command output, which result m true after BGP session is established?

• A.The IOS XR router advertises all routes to the neighbor 192.168.2.2, but it does not accept any routes from 192.168.2.2
• B.The IOS XR router advertises and accepts all routes to and from eBGP neighbor 192.168.2.2 C. No routes are accepted from the neighbor 192.168.2.2, nor are any routes advertised to it
• C.The IOS XR router does not advertise any routes to the neighbor 192.168.2.2,but it accepts all routes from 192.168.2.2.
