300-430 Question 41
Single answerAn enterprise is deploying a Wi-Fi network with voice and video applications that require strict Quality of Service (QoS). The wireless LAN controller is configured with four QoS profiles: Platinum, Gold, Silver, and Bronze. The network administrator wants to ensure that voice traffic receives the highest priority while minimizing the impact on other traffic types. Which QoS profile should be assigned to the SSID used for voice traffic?
- A
Platinum
- B
Gold
- C
Silver
- D
Bronze
Show answer and explanation
Correct answer: A
Explanation
The Platinum QoS profile is explicitly designed for real-time applications like voice and video that require strict prioritization. Assigning this profile to the SSID ensures that voice traffic is handled with the highest priority, minimizing latency and ensuring high call quality.
- A. Correct.
Platinum is the highest QoS profile available, designed to prioritize real-time applications like voice and video. It ensures low latency and high reliability for critical traffic.
- B. Incorrect.
Gold provides a good level of QoS but is typically used for less critical applications like video streaming, which can tolerate slightly higher latency compared to voice.
- C. Incorrect.
Silver is a default QoS profile for best-effort traffic, typically used for basic Internet browsing and file transfers. It does not provide the prioritization needed for voice traffic.
- D. Incorrect.
Bronze is the lowest QoS profile, used for background traffic such as large non-critical file uploads. It is not suitable for real-time applications like voice.
