300-360 Question #100: Real Exam Question with Answer & Explanation
The correct answer is B: Configure EDCA parameters for Voice Optimized.. Configuring EDCA Voice Optimized parameters ensures voice traffic receives prioritized channel access, addressing poor audio performance on Cisco 7925 phones roaming between bands.
Question
Refer to the exhibit. An engineer has determined that Cisco 7925 phones are roaming between 2.4 6Hz and 5 6Hz radios on the same access points, which results in poor audio performance Which action must the engineer take to mitigate this issue?
Exhibit
Options
- AEnable TPCv2 to normalize the RF environment.
- BConfigure EDCA parameters for Voice Optimized.
- CConfigure the Cisco 7925 phone to only use 5 6Hz.
- DEnable Band Select on the WLAN
Explanation
Configuring EDCA Voice Optimized parameters ensures voice traffic receives prioritized channel access, addressing poor audio performance on Cisco 7925 phones roaming between bands.
Common mistakes.
- A. TPCv2 dynamically adjusts AP transmit power to normalize coverage overlap but does not configure the QoS channel-access priorities needed to improve voice traffic quality during band transitions.
- C. Locking the Cisco 7925 to 5 GHz only is a workaround that may create coverage gaps where only 2.4 GHz is available and does not address the underlying QoS parameter issue causing poor audio.
- D. Band Select encourages dual-band clients to prefer 5 GHz during initial association but does not configure QoS parameters that ensure voice traffic receives prioritized channel access for sustained audio quality.
Concept tested. EDCA Voice Optimized QoS for wireless voice clients
