• Question 715:

  Which statements about the relationship between GVRP and GARP are true? (Choose two.)

  A. GVRP, GARP, and GMRP are the standards of the same type.
  B. GVRP and GARP are defined by IEEE 802.1p.
  C. GVRP is based on GARP, and is an application of GARP.
  D. GVRP is a new definition of GARP.
  B. GVRP and GARP are defined by IEEE 802.1p.

• Question 716:

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

  

  A. When VRRP is used to track a BFD or EFM session, if a tracked BFD or EFM session status changes, the BFD or EFM module notifies the VRRP module of the change. After that, the VRRP module implements a rapid master/backup switchover.
  B. A VRRP backup group can monitor a peer BFD session, a link BFD session, and a normal BFD session at the same time. In addition, it can monitor the interface status.
  C. When the status of a BFD session detected by a VRRP backup group changes, the master/slave switchover of routers in the VRRP backup group occurs by changing priorities of the master and slave routers.
  D. A VRRP backup group can monitor several BFD sessions at the same time. The status changes of these BFD sessions affect each other.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 718:

  In OSPF area, RTA and RTB interconnect through FE interface. which of the following commands can be used to configure the link cost between RTA and RTB as 10? (Choose two.)

  A. Use command "ospf cost 10" on two routers
  B. Use command "ospf cost 5" on two routers
  C. Use command "bandwidth-reference 500" on two routers to change bandwidth-reference value
  D. Use command "bandwidth-reference 1000" on two routers to change bandwidth-reference
  A. Use command "ospf cost 10" on two routers
  D. Use command "bandwidth-reference 1000" on two routers to change bandwidth-reference

• Question 719:

  A. Reduce the broadcast domain on the network and the probability of broadcast storms.
  B. Achieve separate convergence of Layer 2 and Layer 3 to increase the convergence speed and network stability.
  C. Properly design the Layer 2 network scale, reduce network segment allocation, and improve network management efficiency.
  D. Allow configuring access devices as Layer 2 devices, reducing network construction costs.
  E. Leverage the STP and VRRP mechanisms to improve network reliability.
  C. Properly design the Layer 2 network scale, reduce network segment allocation, and improve network management efficiency.
  D. Allow configuring access devices as Layer 2 devices, reducing network construction costs.
