Best Practices for Supporting Legacy Clients in a Mixed-Mode Environment
Question
After interviewing the customer to understand its wireless client requirements, you determine that 802.11b must be enabled to support legacy clients within a mixed-mode environment.
What recommendation will have the greatest mitigation on the effects of 802.11b clients on the rest of the network?

A. B. C. D.B.
The greatest mitigation on the effects of 802.11b clients on the rest of the network would be to enable a separate SSID for 802.11b clients. This recommendation will allow you to create a separate virtual network for these clients, providing a way to isolate them from the rest of the network.
Option A, Restricting the use of OFDM modulation, is not a recommended solution as it would limit the overall network throughput and would not address the issue of supporting legacy clients.
Option B, Making 11 Mb/s the lowest mandatory rate, would be a viable solution, but it would limit the overall coverage area and could negatively impact clients that are further away from the access point.
Option D, Enabling short preamble, would not have a significant impact on mitigating the effects of 802.11b clients on the rest of the network. Short preamble is a method to reduce overhead in wireless transmissions, but it would not address the issue of supporting legacy clients.
In summary, creating a separate SSID for 802.11b clients is the best option to mitigate the effects of legacy clients on the rest of the network. This approach would allow for the isolation of these clients while maintaining the coverage and throughput of the network for clients that support newer wireless standards.
