H12-224 practice questions, page 6 of 14, with answer review and explanations.

Question 26

The dynamic LACP requires devices at both ends to exchange protocol packets, while the static LACP does not require so.

  1. True
  2. False

Question 27

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

  1. 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.
  2. 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.
  3. 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.
  4. A VRRP backup group can monitor several BFD sessions at the same time. The status changes of these BFD sessions affect each other.

Question 28

Which of the following numbers is the protocol number of VRRP packets?

  1. 112
  2. 113
  3. 114
  4. 115

Question 29

Traffic shaping usually buffers packets that need to be dropped by traffic policing by means of buffer and token bucket.

  1. True
  2. False

Question 30

In case of congestion, which of the following indexes will affect QoS? (Choose three.)

  1. Transmission delay
  2. Transmission jitter
  3. Packet loss ratio
  4. Transmission distance
