Question 1

Router HW1 runs BGP, and has IBGP peers and EBGP peers configured.

Which of the following statements regarding the IBGP peers and EBGP peers are true?

Select all that apply, then click Submit answer.

  • ○

    The router sends BGP updates learned from each IBGP peer to the other IBGP and EBGP peers.
  • ○

    The IBGP peers must be directly connected. Otherwise, multi-hop IBGP must be configured on the router.
  • ○

    The EBGP peers can establish peer relationships through loopback interfaces.
  • ○

    The router sends BGP updates learned from each EBGP peer to the other EBGP and IBGP peers.
  • ○

    The EBGP peers must be directly connected. Otherwise, multi-hop EBGP must be configured on the router.
Question 2

Which of the following statements about BGP load balancing are false? (Choose three.)

Select all that apply, then click Submit answer.

  • ○

    The AS_Path attribute values of equal-cost routes for load balancing must be different.
  • ○

    When BGP load balancing is implemented, the local device can change the next-hop address of routes to its own address when advertising the routes to IBGP peer groups only if the peer next hop-local command is configured.
  • ○

    Load balancing can be implemented among BGP routes with different origins but having the same destination network segment.
  • ○

    Load balancing can be implemented among IBGP routes and EBGP routes having the same destination on the public network.
Question 3

Which of the following statements regarding a TCP sliding window are false?

Select all that apply, then click Submit answer.

  • ○

    The sender advertises the size of the initial window.
  • ○

  • ○

    The sliding window size can only be increased or remains unchanged.
  • ○

    A TCP sliding window allows the sender to send multiple data packets before receiving an acknowledgment message.
  • ○

    The sender does not need to transmit packets with a complete window size.
