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?

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?

Given: The 802.11ac APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n and
802.11ac amendments. The AP is configured for a single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3×3 802.11n chip that
supports two spatial streams.
What is the maximum MCS rate that could be supported by this AP?

As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your
network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.
What application matches this description?

What VoWiFi implementations frequently require multicast packet delivery support by the WLAN infrastructure?

When live video streaming solutions that transmit simultaneously to more than one recipient are used, what special capability should be considered and configured
in all affected WLAN implementations?

You are selecting external antennas for use in a bridge link deployment. What chart should you request from the antenna vendors to make an accurate selection?

When implementing WLAN security according to common best practices, what feature should be enabled when configuring an EAP type?

In a manufacturing facility with highly reflective materials, you are planning an upgrade to your existing 802.11b WLAN implementation. You have chosen a dualband 802.11n infrastructure product for this purpose. Your client applications include:
Handheld scanners — for inventory management
Toughbooks (laptops) — mounted on forklifts for inventory and workflow management
VoWiFi phones — used by select employees throughout the facility
You are evaluating all of the 802.11n enhancements and determining which features to enable for your environment and applications.
In this scenario, what 802.11n enhancement typically should NOT be enabled on the 2.4 GHz radio of the new APs?

Which one of the following is an essential metric to measure when performing a survey and design for VoIP across WLANs?
