Refer to the exhibits. A user reports slow response time to a network administrator and suggests that there might be a problem with the WLAN. The user’s phone supports 802.11ac in the 5 GHz band. The network administrator finds the user in the Mobility Master (MM) and reviews the output shown in the exhibit. What can the network administrator conclude after analyzing the data?

1. A. The low SNR forces the client to back off to low MCs, therefore speed is low and retransmits are high.
2. B. Client health is poor, but SNR is fair. TX power must be increased in both the client and the AP.
