QUESTION: 76

As an implementation engineer, you have just received initial design specs from a network designer for your dual-band 802.11n deployment. The network design documents prescribe the following data rate configuration for the 2.4 GHz radio:
Basic Rates 5.5, 6, 11, 12 Mbps
Supported Rates 9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15 What will result from this design strategy?

By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force 802.11b clients to use these higher data rates.
Protection mechanisms will always be in use on this network to support 5.5 and 11 Mbps as basic rates.
HR/DSSS (802.11b) stations will not be able to associate to the service set.
This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory data rates for 802.11g/n.

QUESTION: 77

Given: As the wireless network administrator for XYZ Company, you are planning to upgrade your aging wireless network infrastructure, as well as some clients, to support 802.11ac. In your research, you have discovered that your new wireless client devices and infrastructure are 802.11ac,
WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices are 802.11a/b/g devices that do not support WMM.
Given this information, what scenario is possible when your company's employees begin using both types of client devices on the new WLAN?

All WMM-PS certified client devices will be prevented from utilizing WMM-PS features until all stations in use on the wireless medium are
WMM-PS certified.
The WLAN infrastructure will set the dozing times of the WMM-PS certified client devices based upon their WMM access category, while the non-WMM-PS client devices will continue to use PS-Poll frames.
Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client devices when used with applications that support WMM-PS.
WMM-PS enabled APs will allow both WMM-PS and non-WMM-PS stations to use the trigger-and-
delivery mechanism, but WMM-PS stations wil

QUESTION: 79

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine.
Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?
