Refer to the Exhibit

Refer to the exhibit. A network administrator receives a call from a contractor that was recently given wireless access to the network. The user reports that the response time is slow and suggests there might be a problem with the WLAN. The network administrator checks RF performance in AirWave to find the user and sees the output shown in the exhibit. What can the network administrator conclude after analyzing the data?

A) Client health and CNR are high, therefore, it is unlikely the client is experiencing an RF-related issue.
B) Goodput is low in relation to connection speed, which suggests a channel with high utilization, another channel should be used.
C) Client health and SNR are high but usage is low; therefore, there might be packet drops.
D) Client health is low, which suggests that there are packet drops and collisions in the RF environment.
