Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Documentation

Multicast frames over Wi-Fi are traditionally transmitted at the lowest basic data rate, making them slow and unreliable, particularly outdoors where environmental RF effects are more significant.

Aruba provides a feature designed for this scenario:

✅ Dynamic Multicast Optimization (DMO)

Converts multicast streams into unicast transmissions per associated client

Allows the AP to use the highest possible unicast data rate supported

Significantly improves reliability, throughput, and range for critical multicast applications

HPE Aruba documentation statement:

“Dynamic Multicast Optimization increases the reliability of multicast traffic by converting multicast frames to unicast and allows transmissions using higher data rates.”

This directly supports the requirement in the question:

✅ increase reliability

✅ use the highest possible data rate

Why the Other Options Are Incorrect

Option

Reason Incorrect

A. Increase basic rate

Raising basic rates often reduces coverage range and can disconnect distant outdoor clients

B. Multicast Transmission Optimization

This older mode still transmits multicast over the air, not at highest rate

D. Enable WMM

WMM is for QoS prioritization, not for increasing multicast PHY rates or reliability

✅ Final Verified Answer: C. Dynamic Multicast Optimization
