問題3
Which of the following statements are true about the WLAN site survey In different typical scenarios? (Select All that Apply)

A. In an office scenario, the load-bearing columns and partitions affect the signal coverage. If an integrated ceiling is used, deploy APs near maintenance entrances. If a metal ceiling is used, mount APs on the ceiling or wall.

B. In a classroom scenario. If the walls are made of reinforced concrete, the signal attenuation Is high. In this case, you are advised to test the attenuation during the site survey. Additionally, pay attention to the locations of ELV rooms in the teaching building.

C. In a stadium scenario, the onsite environment is complex and cabling is difficult. Therefore, confirm with the property management company about ELV rooms and cabling. If the transmission distance is too long, consider deploying more switches. During the survey, focus on the interference between APs and AP mounting modes.

D. In a ward-round scenario, high requirements are posed on the coverage field strength, roaming effect, and bandwidth. Determine the interference of medical equipment and the areas where Wi-Fi signals are not allowed.

問題4
Differentiated network planning needs to be performed to meet requirements of different IoT services in Huawei's CloudCampus loT solutions. Drag the solutions on the left to their corresponding network planning suggestions on the right.

正確答案:

Explanation
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: :

問題7
Which of the following statements about VXLAN is false?

A. A VBDIF interface is a logical interface created based on a BD. It is similar to a VLANIF interface on a traditional network.

B. A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and communication with external non-VXLAN networks.

C. A Layer 2 VXLAN gateway forwards traffic to a VXLAN network and can also be used for Intra-subnet communication on the same VXLAN network.

D. Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.
