To improve BGP performance in your network, you would like to withdraw routes immediately when the next hop of the route becomes unavailable instead of waiting for the scan interval to detect the problem. Which Cisco IOS software command will configure this failure?

• A.import path selection
• B.bgp dampening
• C.neighbor update-source
• D.bgp inject-map
• E.neighbor fall-over

In an effort to decrease BGP convergence time, the BGP scan timer has been lowered. What is possible side effect of this action?

• A.Batch updates will be held for a shorter time
• B.Maximum packet-per-second throughput will increase.
• C.There are slow or no responses to the console or Telnet sessions
• D.The BGP table can become out of sync with the rest of the network

Which two statements correctly describe the IBGP split-horizon rule?

• A.Updates that are received on an EBGP session are forwarded to IBGP and EBGP.
• B.Updates that are received on an IBGP session can be forwarded to other IBGP peers synchronization is turned off.
• C.Updates that are received on an EBGP session are not back out the EBGP peers that
  are in the same neighboring AS.
• D.Updates that are received on an IBGP session are forwarded to all EGBP peers

Refer to the exhibit. Two Cisco IOS routers that are configured with OSPF cannot establish adjacency. Examine the information that is collected from r1 and r2. Why cannot the adjacency be established?

• A.Network-type mismatch
• B.Different MTU
• C.Subnet mismatch
• D.Area ID mismatch

Which Cisco IOS Software command lengthens the BGP update time reduce the number of updates that are sent when flapping BGP inks are causing network instability?
