- B . Colorize the message
- C . Cache the packets that exceed the traffic limit

Regarding traffic shaping, which of the following description is incorrect?
- A . Compared with traffic policing, traffic shaping has better anti-burst capabilities.
- B . Traffic shaping allows packets to be sent out at a relatively uniform speed.
- C . Due to the introduction of queues, when congestion occurs, the delay of messages increases relatively

In the MPLS VPN network, when the data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels. Regarding the description of the two layers of labels, which of the following options is wrong? (Multiple Choice)
- A . The outer label of MPLS VPN is called the private network label, and the inner label is called the public network label.
- B . The outer label of MPLS VPN is allocated by LDP protocol or statically, and the inner label is allocated by the MP-BGP neighbor of the opposite end.
- C . By default, the outer label is ejected before the packet is forwarded to the last-hop device.
- D . The outer label is used to correctly send the data packet to the corresponding VPN on the PE device.
Regarding the description about the VRRP, which of the following is wrong?
- A . The routers in the VRRP group elect a Master based on priority
- B . The master router sends a gratuitous ARP message to notify its virtual MAC address to the device connected to it.
- C . If the Master router fails, the Backup router in the virtual router will re-elect a new Master based on the priority
- D . Because the priority range is 1-255, when the priority value in the VRRP notification message received by the Backup device is 0, Backup will discard the message without any processing.
