NEW QUESTION # 18
Drag the reasons for AP onboarding failures on the left to the corresponding troubleshooting operations on the right.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the troubleshooting operations for the AP onboarding failures are as follows:
APS fail to be authenticated by the WAC: Whitelist the APS. The WAC can authenticate APs based on their MAC addresses or SNs. If an AP is not whitelisted on the WAC, it cannot be authenticated and onboarded.
License resources on the WAC are insufficient: Expand the license capacity. The WAC can manage a limited number of APs based on its license. If the license resources are insufficient, some APs cannot be onboarded.
APS fail to obtain IP addresses: Check the DHCP server. The APs need to obtain IP addresses from a DHCP server before they can communicate with the WAC. If the DHCP server is not configured or reachable, the APs cannot obtain IP addresses and onboard.
APS fail to ping the WAC: Check the network between the WAC and APS. The APs need to ping the WAC to discover its IP address and establish a CAPWAP tunnel. If there is a network problem between the WAC and APs, such as incorrect VLAN configuration or firewall blocking, the APs cannot ping the WAC and onboard.
Therefore, APS fail to be authenticated by the WAC - c, License resources on the WAC are insufficient - b, APS fail to obtain IP addresses - d, APS fail to ping the WAC - a is the correct answer. References: :

NEW QUESTION # 23
802. 11r fast roaming (over-the-air) is enabled on the WLAN shown in the figure. A STA roams from AP1 to AP2. Sort the steps in chronological order during the 802.11r fast roaming process between WACs.
Answer:
Explanation:
Explanation
According to the Huawei documents and resources, the chronological order during the 802.11r fast roaming process between WACs is as follows:
2.The STA accesses the network through API. This is the initial association process before roaming.
1.The STA initiates an 802.11 FT authentication request to AP2. This is the first step of the roaming process when the STA moves to a new AP.
3.AP2 starts the reassociation timer, and sends an 802.11 FT authentication response to the STA. This is the second step of the roaming process when AP2 responds to the STA's request and sets a timer for reassociation.
4.The STA generates and installs a P TK based on the information contained in the response frame. This is the third step of the roaming process when the STA derives a new pairwise key for encryption.
5.The STA sends a reassociation request to AP2. This is the fourth step of the roaming process when the STA requests to reassociate with AP2.
6.AP2 generates and installs a PTK according to PMK-RI and information contained in the request frame. This is the fifth step of the roaming process when AP2 derives the same pairwise key as the STA.
7.After receiving the reassociation request, AP2 disables the reassociation timer, and then sends a reassociation reg onse to the STA. This is the sixth step of the roaming process when AP2 confirms the reassociation with the STA and stops the timer.
8.The STA receives the response frame of AP2. The roaming process is complete. This is the final step of the roaming process when the STA completes the handover to AP2.
Therefore, 2, 1, 3, 4, 5, 6, 7, 8 is the correct answer. References:
