What is the purpose of DHCP Option 43, and how is it used with WLANs?

Given: A WLAN controller is connected to ABC Company’s core layer 3 Ethernet switch with an IEEE
802.1Q trunk connection. The WLAN controller’s native VLAN is VLAN 6 and its IP address is
10.0.14.2 /24. Lightweight APs supporting centralized forwarding are connected to the network on VLANs 7,
8, and 9, and they each build a layer 3 tunnel back to the WLAN controller’s IP address. The dynamically
assigned IP addresses received by each AP from a DHCP server will be ________________.

An associated STA detects a new BSS with the same SSID as the STA’s current BSS. The new BSS uses
a different IP subnet than the current BSS. If the STA is configured to use 802.1X/EAP preauthentication,
what is likely to occur?

In a multiple channel architecture (MCA) network supporting 802.1X authentication, what aspects of WLAN
design affect client roaming efficiency and effectiveness? (Choose 3)

Given: For this fill-in the blank question, each answer option contains an answer for the first and second
blanks, separated by a dash “–“. Choose the answer option that correctly fills in both blanks in the following
sentence.
A WLAN may use 802.11 admission control to ________, and admission control requirements are
configured separately for each ________.

In a large enterprise (5000+ wireless users), by what recommended methods are IP addresses and VLANs
assigned to different clients associated to the same AP? (Choose 3)

Given: Use the exhibit as a reference. ABC Company has a WLAN controller with 10 controller- based APs;
the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a
layer-2 Ethernet switch. Each layer-2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN
controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all
controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch.

When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCPvalue carried in the STA’s IP data packet gets mapped to what and by which device?

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 802.11e AC_VO priority level?

You are tasked with designing the WLAN to accommodate certain high density areas on your university
campus where users are highly transient (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 associations. The DHCP server is a
Windows Server 2008 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?
