A coffee shop wants to offer free guest Wi-Fi while keeping business traffic separate. Which WLAN design element achieves this?
Answer: Use multiple SSIDs mapped to separate VLANs for guest and corporate traffic
Multiple SSIDs mapped to separate VLANs allow traffic segmentation between guest and corporate networks on shared AP infrastructure.
What is the impact of enabling too many SSIDs on a single AP in a WLAN design?
Answer: Each SSID consumes air time for beacons, reducing overall network efficiency
Each SSID requires periodic beacon transmissions that consume airtime, so excessive SSIDs reduce overall network efficiency and client throughput.
In Aruba WLAN design, what is the role of 802.11k neighbor reports?
Answer: To provide clients with a list of nearby APs to assist in roaming decisions
802.11k allows APs to provide clients with neighbor AP information, enabling smarter and faster roaming decisions.
A client device is stuck on a distant, weak AP despite a closer AP being available. Which Aruba feature addresses this 'sticky client' problem?
Answer: ARM's Client Match feature
Aruba's Client Match actively steers clients away from overloaded or weak APs to better alternatives, resolving the sticky client problem.
When designing a WLAN for a medical facility, which frequency band should be preferred and why?
Answer: 5 GHz, because it offers more non-overlapping channels and less interference from medical equipment
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.
What is the primary reason to conduct a post-deployment validation survey after AP installation?
Answer: To verify actual coverage, signal strength, and throughput meet design requirements
Post-deployment surveys confirm that real-world coverage and performance match the design specifications and identify any gaps or problem areas.
Which Aruba solution provides centralized RF management and automatic channel and power adjustments across all APs?
Answer: Aruba Adaptive Radio Management (ARM)
Aruba ARM continuously monitors the RF environment and automatically adjusts channel assignments and transmit power to optimize network performance.
