NEW QUESTION 37
A network administrator assists with the migration of a WLAN from a third-party vendor to Aruba in different locations throughout the country.

Ever since the MC seems to reject PAPI sessions from the switch with the 10.1.10.10 IP address. Also the controller's prompt is now followed by a star mark: "(MC_VA) [mynode] *#" When opening a support ticket, an Aruba TAC engineer asks the administrator to gather the crash logs and if possible replicate UBT connection attempts from the switch while running packet captures of PAPI traffic on the controller and obtain the PCAP files.

What can the network administrator conclude after analyzing the data?
- A. Since SNR is good, then the high retransmit rate must be due a hidden node scenario or high interference.
- B. The low SNR forces the client to back off to low MCs. therefore speed is low and retransmits are high.
