88. S switch V600R022 version, regarding the IPV6 RGuard implementation description, the incorrect one is ().

RA messages can carry a lot of network configuration information, including key network configuration information such as the default router, network prefix list, and whether to use a DHCPv6 server for stateful address allocation. The attacker modifies the network configuration of the user's host by sending forged RA messages, making it impossible for legitimate users to communicate normally. IPv6 RGuard provides a defense mechanism against RA message attacks, which can effectively prevent such network attacks.

Configure the user (host) or router (router) role for the interface, and the device then chooses to forward or discard RA messages based on the interface role.

If it is determined that the interface is connected to a user host, configure the interface role as user (host); if it is determined that the interface is connected to a router, the administrator can configure the interface role as router (router) according to the interface in the network.

89. Regarding the description of the WLAN network planning solution for the one-to-two scenario of a dormitory/hotel with a bathroom at the door, the correct one is ().

Select the butterfly wing wave AP wall-mounted installation in the bathroom corner, with a height of 2.2~2.5m. A single AP covers the left and right rooms.

The AP fixes the radio frequency power and configures the maximum EIRP value to improve downlink coverage in the wall-through room. The worst 5G downlink RSSI is -65dBm, and the worst uplink RSSI is -80dBm.

Separately deploy indoor omnidirectional APs (2*2 models such as 5761-11) in the corridor to ensure roaming continuity. The bathroom relies on 5G for coverage and turns off 2.4

The bathroom relies on 5G for coverage and turns off 2.4G

90. In the campus SDN solution, which statement is wrong about the distributed gateway solution?

In distributed gateway-VxLAN to access, independent AC scenarios, local forwarding mode deployment is not recommended for wireless traffic.

Distributed gateway-VxLAN to access, independent AC scenario, enter VN from edge, execute business mobility policy on edge (edge needs to subscribe to IP-Group service), the current solution supports automated deployment.

The VTEP device is both an L2 gateway and an L3 gateway. Non-gateway nodes are not aware of VXLAN tunnels and only serve as forwarding nodes for VXLAN packets.

In the distributed gateway-VxLAN to aggregation, on-board AC scenario, the accompanying policy for wireless traffic services is executed on the edge, and tunnel forwarding is recommended.
