Why is a high CRC error rate in L2 protocol analysis software NOT always a valid indicator of network performance? (Choose 3) A. If protocol analysis software is not properly configured with frame decryption parameters, it can’t accurately calculate a…
As a WLAN consultant, you have been asked to troubleshoot a problem with a single wireless client station (Station-Z). Your customer informs you that other wireless client stations are not having problems with wireless connectivity, and that Station-Z is configured…
Shown is a screenshot of a wireless protocol analyzer displaying the decode information for a single 802.11 encrypted data + CF-Poll frame. The infrastructure BSS on which this information was captured is using WEP and this particular frame was sent…
Given the screenshot shown, Choose the statement that accurately describes what is being seen by this protocol analyzer. A. Three access points are on the same channel in the same physical area. B. A Single Channel Architecture (SCA) WLAN solution…
Given the IEEE 802.11 Beacon frame decode shown, determine which statement is definitively true. A. The access point is operating on channel 3. B. The access point has both 1 Mbps and 2 Mbps configured as basic rates. C. This…
When 802.11 standard compliant AES-CCMP security is being used with IPSec/ESP for layered security, what will a WLAN protocol analyzer see as the security mechanism in use when a user browses to an HTTPS secured web page? A. AES-CCMP B.…
Given: There are many differences between analyzing wireless and wired networks. In a wireless network, there is no guarantee that one station can hear another station’s transmissions. If no corrective actions are taken nor corrective mechanisms implemented when a "hidden…
ABC Company’s WLAN administrator is getting complaints from one user that his WLAN throughput is sluggish compared to other users in his area. The administrator takes his diagnostics laptop, which has a wireless protocol analyzer installed, to the area where…
Given: Shown are frames captured from an IEEE 802.1X/LEAP authentication. This WLAN is a Robust Security Network (RSN) using the CCMP cipher suite. Using the information given in the screenshot, calculate how long it takes for only the frames that…
While at a government-operated facility, you are attempting to troubleshoot a WLAN performance problem using a wireless protocol analyzer. When you start capturing frames, you see a proprietary layer 2 protocol running over the ERP network as shown in this…
