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

• 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.
• 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.
• 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.
• 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.

Either of the two APs that have established a mesh connection can send a Mesh Peering Close frame to the other AP to tear down themesh connection.

• True
• False

Which of the following items is not involved in the HLD phase?

• Capacity planning
• Network design
• AP position planning
• Deployment planning

Which of the following configurations may cause ST As to experience a slow Internet connection? (Select All that Apply)

• QoS CAR is configured in the traffic profile.
• Radio 1 of APs is disabled.
• TKIP encryption is configured, causing a low link setup rate.
• Rate limiting is configured in the SSID profile.

Which of the following statements about attack defense is true?

• Defense against flood attacks can be used to defend against Ping of Death attacks.
• Attack defense 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.
• Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.
• Fragmentation attack defense enables a device to detect packet fragments in real time and discard or rate-limit them to protect the device.

Which of the following statements about the access layer design are true when Huawei's CloudCampus Solution is applied to small and midsize campus networks? (Select All that Apply)

• In the mini-store scenario, APs and egress devices must be deployed if Wi-Fi coverage is required. APs cannot directly connect to egress links and do not support NAT.
• When selecting a switch, ensure that the following condition is met; Number of connected APs x AP power ^ Power provided by the PoE switch. Therefore, select PoE switches with a proper power supply based on the AP model and quantity.
• Select appropriate models of access switches based on whether PoE support is required and how many APs need to access the network.
• For relatively large networks in midsize shopping malls, supermarkets, and primary/secondary education campuses, it is recommended that stack networking be used at the access layer. If a single device can provide sufficient access capacity for downstream terminals, single-device networking can be used at the access layer. If the upstream devices of access-layer devices are stacked, it is recommended that Eth-Trunks be used to connect to such upstream devices. If more APs need to be deployed, use the PoE switch to increase the number of APs to be connected.

Which of the followings is an IPv6 multicast address?

• 2222::11
• FF02::18C
• FE80:: A
• FC00::1

Which of the following parameters can be allocated to clients In DHCPv6 stateful autoconflguratlon? (Select All that Apply)

• IPv6 address
• PD prefix
• SNTP server address
• DNS server address

Which of the following key factors is used by the CloudCampus cloud management platform to determine the tenant to which a device belongs?

• Device ESN
• Device IP address
• Device MAC address
• Device model

To which of the following scenarios is radio calibration applicable?

• Enterprise office scenario
• Rail transportation scenario
• High-density scenario
• WDS or mesh backhaul scenario
