MP: Mesh node that uses IEEE 802.11 MAC and PHY protocols for wireless communication. This node
supports automatic topology discovery, automatic route discovery, and data packet forwarding. It
can provide both mesh service and user access service1.
MPP: MP node that connects a WMN to MPs on other types of networks. This node can function as a
portal for communication between internal mesh nodes and external networks1.
Neighbor MP: Neighboring MP with which an MP prepares to establish a mesh link1.
Candidate MP: AP that directly communicates with a mesh node2.

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.
