Question 80
A voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. Which immediate engineering change most directly addresses this issue?
Explanation
Correct Answer
The underlying issue is that repeated full key exchanges during roaming can add latency beyond voice application tolerance. This intervention addresses that cause directly. A useful result to confirm is: voice clients roam with acceptable handoff time and retained security.
Incorrect Answers
This is suited to a different condition, such as when a large office wants better distribution of capable clients between 2.4 and 5 GHz but all steer to 2.4 after a new RF policy. The reported fault instead arises because repeated full key exchanges during roaming can add latency beyond voice application tolerance.
This is suited to a different condition, such as when a location-aware application cannot find good roam candidates although coverage overlaps because neighbor information is missing. The reported fault instead arises because repeated full key exchanges during roaming can add latency beyond voice application tolerance.
This is suited to a different condition, such as when a deployment reports high AP client counts but users complain about slow uploads during busy classes. The reported fault instead arises because repeated full key exchanges during roaming can add latency beyond voice application tolerance.
