A: True: TheAirEngine 6760R-51, a rugged outdoor Wi-Fi 6 AP,supports IoT expansionvia Huawei'sIoT cards.
B: False: Huawei IoT expansion is implemented viaIoT cards and dedicated expansion modules,not PCIe or USB.
C: False: Huawei supportsmultiple IoT protocols, includingBLE, RFID, Zigbee, andNB-IoT, not just RFID and Bluetooth.
D: False: AlthoughHuawei minimizes interferencethrough smart scheduling,some spectrum overlap may still occur, andco-channel interference is always considered in planning.

TheHuawei CloudEngine S8700series supportscluster-based active-active architecture, offering:
50 ms-level failover
Hot patching and ISSU (In-Service Software Upgrade)
Service continuity during upgrade and fault scenarios
UnlikeVRRP, which is used for gateway redundancy, orM-LAGandstack, which are link or port-level mechanisms,the cluster solution provides full-device-level failover and operational continuity.

Option D is false. The AirEngine 6776I-X7TH is an indoor high-density AP and does not have built-in omnidirectional antennas; instead, it often uses external directional antennas, particularly when deployed in large venues like stadiums or exhibition centers.
Correct information for other options:
A: IP68 is indeed the highest industry standard for dust/water resistance in outdoor APs.
B: The AirEngine 8760R-X1 supports BLE 5.0 and can deliver PoE output to other devices (such as cameras).
C: The AirEngine 6760R-51/51E supports tri-radio with a combined rate of up to 10.75 Gbps.
