Exam HPE6-A70 topic 1 question 5 discussion

C is the correct answer. ClientMatch Load Balancing: Client match balances clients across APs on different channels, based upon the client load on the APs and the SNR levels the client detects from an underutilized AP. If an AP radio can support additional clients, the AP will participate in client match load balancing and clients can be directed to that AP radio, subject to predefined SNR thresholds.

AirMatch is Aruba’s next generation automatic RF planning service. This can replace the legacy solution—ARM’s automatic channel and power assignment. AirMatch only runs on the MM, running AOS 8.0 or higher. For a standalone MD, or Controllers, running in Master/Local mode ARM will perform the RF optimization. While ARM and AirMatch focus more on RF management at the AP level, Client Match (CM) focuses on the client level. For example, three clients were associated with AP 115. However, after the Client Match process, two of the clients were moved from AP 115 to AP 335. CM determined that better client services could be achieved with this change.

per ArubaOS 8.7.1.0 user guide, p 567 "ClientMatch balances clients across APs on different channels" I believe the word "client" is missing before "accross" in the question "to balance wireless across". Answer is C

AirMatch is only supported in Mobility Master architecture. ARM is used on stand-alone and Master -local set ups

D is correct: While ARM and AirMatch focus more on RF management at the AP le vel, Client Match focuses on the client level. Aruba Client Match is an Aruba pa tented technology which provid es you these three main functions: 1. Load Balancing: Client match balances clients across APs on different channels based upon the client load. 2. Sticky Clients: Client match helps clients that tend to stay associated to an AP despite low signal levels.

The key words are client and balance, which legacy client match manages client RF services, as well as balance clients across APs.

C makes sense if it means "..balance wireless *CLIENTS* across APs on different channels"
