ABC Company is a small company that has hired you to troubleshoot an intermittent performance problem with their ERP WLAN. They have noticed that intermittently throughout a typical day, their WLAN’s latency increases enough to interrupt some mission critical applications. Considering that ABC Company has no baseline analysis, what possible first step do you take toward troubleshooting ABC Company’s wireless network problem?

A.
Using a protocol analyzer, you search for rogue access points that might be causing interference in the 2.4 GHz ISM band by emitting Beacons.

B.
You install protocol analyzer probes near each access point in order to see if a large percentage of data frames are carrying their maximum payload over the next two days.

C.
You perform a protocol analysis of ABC Company’s premises looking for ERP Basic Service Sets that have both HR-DSSS and ERP stations associated. You then compare this information to where the latency is being experienced.

D.
Using a protocol analyzer, you search for wireless clients that are transmitting too many Probe Request frames and temporarily replace them as a troubleshooting measure.
