Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 47

An enterprise has moved most services to the cloud, including email applications and real-time communication. Which feature must be enabled on the wireless network to improve the user experience?

Answer options

• A. radio management
• B. fast secure roaming
• C. QoS
• D. interference mitigation

Correct answer: C

Explanation

QoS (Quality of Service) is essential for prioritizing network traffic, ensuring that critical applications like email and real-time communication perform optimally. While radio management and interference mitigation help with connectivity and signal quality, they do not specifically enhance the performance of applications in the way that QoS does. Fast secure roaming facilitates quick transitions between access points but does not directly address the quality of service for applications.
