In 802. IX authentication, if the RADIUS server has insufficient processing capability to parse a large number of EAP packets and complete authentication, the EAP______mode should be used. (Enter only lowercase letters.)
Which of the following parameters can be allocated to clients In DHCPv6 stateful autoconflguratlon? (Select All that Apply)
Inter-WAC roaming and intra-WLAN roaming are supported in dual-link HSB scenarios.
Which of the following statements are true about Huawei ' s smart roaming solution?
Huawta WACs support the setting of the RTS/CTS threshold. If the packet length exceeds the threshold, the AP sends RTS frames to clear the channel before sending data frames. If the packet length is less than the threshold, the AP does not use this mechanism. This prevents conflicts caused by hidden STAs.

Which of the following statements is false about STA roaming tracks on a Huawei WAC?
Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)
After multicast-to-unicast conversion is enabled on an AP ' s air interface, which of the followings is the destination MAC address of multicast packets sent over the air interface?
Which of the following user access authentication modes are supported In Huawel ' s CloudCampus Solution? (Select All that Apply)
Huawei Agile Cloud Authentication (HACA) supports only IMaster NCE-Campus as the HACA server.
Which of the following statements are true about the site survey for an outdoor bridge backhaul project?

Which of the following statements are true about network optimization measures?
DHCPv6 stateful autoconfiguration enables a DHCPv6 server to automatically assign IPv6 addresses, PD prefixes, and other network configuration parameters, such as DNS, NIS, and SNTP server address.
Which of the following statements about the authentication rules of the RADIUS server are true?
Radio frequency identification (RFID) is a non-contact automatic identification technology that automatically identifies objects. Which of the following components are included in a typical RFID system?
Master NCE-Campuslnsight analyzes network issues during correlation analysis of poor-QoE clients, including coverage, interference throughput, and hardware issues.
In centralized gateway deployments, border nodes are used as gateways, facilitating centralized management and simplifying O & M. In distributed gateway deployments, edge nodes are used as gateways, facilitating network expansion.
