• Question 382:

  In a switching network that has been enabled with STP protocol, the priorities of all the switches are the same. The MAC address of switch1 is 00-e0-fc-00-00-40, MAC address of switch2 is 00-e0-fc-00-00-10, MAC address of switch3 is 00e0-fc-00-00-20, and MAC address of switch4 is 00-e0-fc-00-00-80. Which of the switches will be elected as the Root Bridge?

  A. Switch1

• Question 383:

  Which of the following statements about VRRP are true? (Choose three.)

  A. VRRP determines the roles of routers (master or backup) in a virtual router based on their priorities.
  B. If a backup router works in non-preemption mode and has a higher priority than the masterrouter, it will become the master router unless the master router fails.
  C. After a backup router in preemption mode receives a VRRP packet from the master router, it compares its priority with the priority carried in the VRRP packet. If its priority is higher than the priority of the master router, it preempts to be the master router; if not, it remains in the backup state.
  D. If two routers competing for the master router have the same priority, the router with a higher interface IP address becomes the master router.

  A. The parameter field in the IP packet header informs devices on the network of the QoS requirements of the application.
  B. Every device on the packet transmission paths can learn the service request types by analyzing the IP packet header.
  C. Before sending packets, the application program needs to confirm that the network has reserved resources for packet transmission.
  D. DiffServ is a QoS solution based on packets.
  C. Before sending packets, the application program needs to confirm that the network has reserved resources for packet transmission.
