Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 25

A wireless deployment in a high-density environment is being used by vendors to process credit card payment transactions via handheld mobile scanners. The scanners are having problems roaming between access points in the environment. Which feature on the wireless controller should have been incorporated in the design?

Answer options

• A. RX-SOP
• B. 802.11w
• C. AP Heartbeat Timeout
• D. Application Visibility Control

Correct answer: A

Explanation

The correct answer is A, RX-SOP, which helps improve the performance of devices in high-density scenarios by managing the signal quality and enabling better roaming between access points. The other options, while useful for various functionalities, do not specifically address roaming issues in a high-density environment as effectively as RX-SOP does.
