Question 8

As a wireless network consultant you have been called in to troubleshoot a high-priority issue for one of your customers. The customer’s office is based on two floors within a multi-tenant office block. On one of these floors (floor 5) users cannot connect to the wireless network. During their own testing the customer has discovered that users can connect on floor 6 but not when they move to the floor 5. This issue is affecting all users on floor 5 and having a negative effect on productivity.

To troubleshoot this issue, you perform both Spectrum and Protocol Analysis. The Spectrum Analysis shows the presence of Bluetooth signals which you have identified as coming from wireless mice. In the protocol analyzer you see the top frame on the network is Deauthentication frames. On closer investigation you see that the Deauthentication frames’ source addresses match the BSSISs of your customers APs and the destination address is FF:FF:FF:FF:FF:FF:FF.

What do you conclude from this troubleshooting exercise?

Options:

A.

The customer should replace all their Bluetooth wireless mice as they are stopping the users on floor 5

from connecting to the wireless network

B.

The users on floor 5 are being subjected to a denial of service attack, as this is happening across the

entire floor it is likely to be a misconfigured WIPS solution belonging to the tenants on the floor below

C.

The customers APs are misbehaving and a technical support case should be open with the vendor

D.

The CCI from the APs on the floor 4 is the problem and you need to ask the tenant below to turn down their AP’s Tx power

Question 9
