NEW QUESTION 26
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.

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:

NEW QUESTION 28
Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)

In EAP relay mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server.

In EAP termination mode, an access device encapsulates EAP packets sent by an 802. IX client Into RADIUS packets, without processing the data in the EAP packets.

In EAP termination mode, an access device extracts client authentication information from the EAP packets sent by a client and encapsulates the information using the standard RADIUS protocol. The access device supports only the EAP MD5-Challenge authentication method.

The EAP termination mode simplifies the processing on an access device and supports various authentication methods. However, this mode requires an authentication server to support EAP and have high processing capability.

Explanation
A: In EAP termination mode, an access device encapsulates EAP packets sent by an 802. IX client Into RADIUS packets, without processing the data in the EAP packets. This statement is false because in EAP termination mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server2.
D: The EAP termination mode simplifies the processing on an access device and supports various authentication methods. However, this mode requires an authentication server to support EAP and have high processing capability. This statement is false because it describes the EAP relay mode, not the EAP termination mode2.
Therefore, A and D are the correct answers. References: 2:
