• Question 171:

  The formula for calculating the MTTR is: MTTR = Fault detection time + Board replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time. The smaller the addends are, the smaller the MTTR is and the higher the device availability is.

  B. False
  A. True

• Question 172:

  Which statements about the PVID on the access interface are true? (Select 3 Answers)

  A. When receiving a packet without the VLAN tag, the interface adds the VLAN tag to the packet and sets the VID in the tag to the default VLAN ID.
  B. When receiving a packet with a VLAN tag, the interface compares the VLAN ID in the tag with the default VLAN ID. If they are the same, the interface forwards the packets; otherwise, the interface discards the packets.
  C. When the interface sends a packet with a VLAN tag that contains the default VLAN ID, the system removes the VLAN tag of the packet, and then forwards the packet.
  D. None of the above.
