H12-351_V1.0 Exam Dumps : HCIE-WLAN (Written) V1.0

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, the AP periodically sends Echo packets to the WACs to detect link status. The Echo packets are sent every 30 seconds by default.

According to the Huawei documents and resources, the network planning suggestions for the solutions are as follows:

• Asset management: The RFID signal coverage distance is 25 m. Therefore, RFID signal coverage must be considered during AP deployment planning. Attach RFID tags on the surface or top of assets to prevent signals from being blocked.
• ESL: Shelves may be blocked in application scenarios. Therefore, shelf blocking must be considered during network planning. The shelves can be deployed in aisles to minimize obstacles toward integrated base stations.
• Smart healthcare: For applications that support regional positioning, positioning devices need to be deployed at key entrances and exits based on service requirements.

Therefore, Asset management - 2, ESL - 1, Smart healthcare - 3 is the correct answer. References: : : :

When a STA roams from AP1 to AP2 at Layer 2, AP2 notifies its neighbors of the MAC address learned from this STA. The MAC address is not encapsulated in a tunnel and sent to AP1 for forwarding. Instead, AP1 deletes the MAC address entry of the STA and releases the IP address lease.
