質問 # 41
switch V600R022 version, about the PV6 RGuard implementation description, the incorrect is ()
- A. 22.0 also supports policy-based filtering of ND packets.
- B. If the interface is connected to the user host, the interface role is set to host, and if the interface is connected to the router, the administrator can configure the interface role to router according to the interface networking. Version 22.0 also supports policy-based filtering of ND packets.
- C. RA packets can carry a lot of network configuration information, including the default router, network prefix list, and whether to use a DHCPv6 server for stateful address allocation. An attacker can send forged RA packets to modify the network configuration of the user's host so that legitimate users cannot communicate properly. IPv6RGuard provides a defense mechanism against RA packet attacks, which can effectively prevent such network attacks.
- D. Configure the host or router role for the interface, and then the device can forward or discard RA packets based on the interface role.
正解：A

質問 # 44
In the LAN-WAN convergence scenario, the description of RR deployment design principles is wrong ()
- A. Use the RR model recommended in the specification list;
- B. Try to choose an independent RR, which can be deployed on a single device in the independent RR scenario.
