ACMA WLAN Design 5

Question 1

A coffee shop wants to offer free guest Wi-Fi while keeping business traffic separate. Which WLAN design element achieves this?

Accepted Answer

Use multiple SSIDs mapped to separate VLANs for guest and corporate traffic

Answer

Multiple SSIDs mapped to separate VLANs allow traffic segmentation between guest and corporate networks on shared AP infrastructure.

Question 2

What is the impact of enabling too many SSIDs on a single AP in a WLAN design?

Accepted Answer

Each SSID consumes air time for beacons, reducing overall network efficiency

Answer

Each SSID requires periodic beacon transmissions that consume airtime, so excessive SSIDs reduce overall network efficiency and client throughput.

Question 3

In Aruba WLAN design, what is the role of 802.11k neighbor reports?

Accepted Answer

To provide clients with a list of nearby APs to assist in roaming decisions

Answer

802.11k allows APs to provide clients with neighbor AP information, enabling smarter and faster roaming decisions.

Question 4

A client device is stuck on a distant, weak AP despite a closer AP being available. Which Aruba feature addresses this 'sticky client' problem?

Accepted Answer

ARM's Client Match feature

Answer

Aruba's Client Match actively steers clients away from overloaded or weak APs to better alternatives, resolving the sticky client problem.

Question 5

When designing a WLAN for a medical facility, which frequency band should be preferred and why?

Accepted Answer

5 GHz, because it offers more non-overlapping channels and less interference from medical equipment

Answer

5 GHz is preferred in medical environments because it offers more non-overlapping channels and is less likely to be congested by medical devices that often use 2.4 GHz.
