Q42. What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)

AP1 will cache the client’s information and send it to the Key Management service

The Key Management service receives from AirMatch a list of all AP2’s neighbors

The Key Management service receives a list of all AP1 s neighbors from AirMatch.

The Key Management service then generates R1 keys for AP2’s neighbors.

A client associates and authenticates with the AP2 after roaming from AP1

Explanation
The correct steps that are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2 are A and D.
A: AP1 will cache the client’s information and send it to the Key Management service. This is true because when a client associates and authenticates with AP1, AP1 will generate a pairwise master key (PMK) for the client and store it in its cache. AP1 will also send the PMK and other client information, such as MAC address, VLAN, and SSID, to the Key Management service, which is a centralized service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) devices1. The Key Management service will use this information to facilitate fast roaming for the client.
D: The Key Management service then generates R1 keys for AP2’s neighbors. This is true because when the Key Management service receives the client information from AP1, it will use the PMK to derive R0 and R1 keys for the client. R0 keys are used to generate R1 keys, which are used to generate pairwise transient keys (PTKs) for encryption. The Key Management service will distribute the R1 keys to AP2 and its neighboring APs, which are determined by AirMatch based on RF proximity2. This way, when the client roams to AP2 or any of its neighbors, it can skip the 802.1X authentication and use the R1 key to quickly generate a PTK with the new AP3.
B: The Key Management service receives from AirMatch a list of all AP2’s neighbors. This is false because the Key Management service does not receive this information from AirMatch directly. AirMatch is a feature that runs on MCs or MM devices and optimizes the RF performance of Aruba devices by using machine learning algorithms. AirMatch periodically sends neighbor reports to all APs, which contain information about their nearby APs based on signal strength and interference. The APs then send these reports to the Key Management service, which uses them to determine which APs should receive R1 keys for a given client2.
C: The Key Management service receives a list of all AP1 s neighbors from AirMatch. This is false for the same reason as B. The Key Management service does not receive this information from AirMatch directly, but from the APs that send their neighbor reports.
E: A client associates and authenticates with the AP2 after roaming from AP1. This is false because a client does not need to authenticate with AP2 after roaming from AP1 if it has already authenticated with AP1 and received R1 keys from the Key Management service. The client only needs to associate with AP2 and perform a four-way handshake using the R1 key to generate a PTK for encryption3. This is called fast roaming or
802.11r roaming, and it reduces the latency and disruption caused by full authentication.1: ArubaOS 8.7 User Guide 2: ArubaOS 8.7 User Guide 3: ArubaOS 8.7 User Guide : ArubaOS 8.7 User Guide
