According to the Huawei documents and resources, the HLD phase is the high-level design phase of a WLAN project. It involves the following items:

Capacity planning: Determines the number and types of devices required for the WLAN network based on the customer’s requirements and network scale.

Network design: Designs the network topology, IP addressing scheme, VLAN division, security policies, and other network parameters for the WLAN network.

Deployment planning: Plans the deployment sequence, schedule, resources, and risks for the WLAN project.

AP position planning is not involved in the HLD phase. It is part of the LLD phase, which is the low-level design phase of a WLAN project. It involves the detailed design of AP positions, antenna types, channel allocation, power adjustment, and other wireless parameters for the WLAN network. Therefore, C is the correct answer.

Attack defense is a feature that allows APs to analyze the contents and behaviors of incoming packets on ports to determine whether packets have attack characteristics. The APs then take defense measures on the packets that have attack characteristics, such as discarding them or limiting their rate. Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.

The display sync-configuration compare command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization. The command output shows the differences between the configurations on the master and backup WACs. In this case, the configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

A mesh connection can be torn down by either of the two APs that have established it by sending a Mesh Peering Close frame to the other AP. This frame indicates that the sender no longer wants to maintain the mesh connection.

B is false because generally, a STA roams when it detects that the signal strength is less than -70 dBm or -65 dBm, not -75 dBm.

A router is not included in a typical RFID system. A typical RFID system consists of three components: RFID tag, RFID reader, and information processing platform. The RFID tag is attached to the object to be identified, the RFID reader communicates with the tag and reads its information, and the information processing platform processes and stores the data collected by the reader.
