Question # 5

ABC Company is planning to install a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey.During the interview with the network manager, you are told that the new Ethernet edge switches will support VoIP phones and 802.11 access points, both using 802.3 PoE.After hearing this information, what immediate concerns do you note?

A. The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.
B. The edge Ethernet switches should support Ether-channel to get the best results out of the network.
C. VoIP phones and 802.11 access points should not be powered by the same edge switch due to distortion.
D. If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for 802.11 APs

Question # 10

You are troubleshooting a client problem with a 2.4 GHz WLAN connection. The client is experiencing surprisingly low data rates during the work day. You analyze the workspace outside of business hours and detect a strong signal with a typical noise floor at the client location. During working hours, the user works with a laptop in the area and uses an external USB hard drive for continuous data access. The user also states that the laptop works as expected on her home network. The user working approximately 8 feet away from this client experiences no problems.Based on this information, what is the likely cause of the problem?

A. The laptop has a failing wireless adapter
B. the AP is overloaded during the work day
C. The external hard drive is USB 3.0 and is causing a significant increase in the noise floor when in use
D. The drives in the laptop are corrupt
