You are working on a VoWLAN design with your customer’s wired networking team. How many distinct priority levels do you expect for the voice applications?

What is the DSCP Per Hop Behavior equivalent classification of the 802.11 AC_VO priority level?

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?

You desire to achieve a 450 Mbps MCS. What 802.11n features (from the numbered list below) are required?
1. Frame aggregation
2. Short GI
3. 40 MHz channels
4. 2 spatial streams
5. 3 spatial streams
6. Transmit beamforming (TxBF)

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?
