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?
A. radio management
B. fast secure roaming
C. QoS
D. interference mitigation
Answer: B
The answer could either B or C. Since QoS is a topic in Exam 300-430 and not 300-425, the Answer is B on the 300-425 exam.
C – “Quality of service (QoS) is one of the most important cornerstones of any network deployment. Without QoS, applications will not function predictably and the user experience will suffer. There is nothing worse than being on a video conference and having your session interrupted by pixelation caused by bandwidth limitations, packet loss, or just poor network performance.” on page 242, Chapter 11 in Cert Guide (300-430)
B – “Any time a client roams to a different AP, it must go through the entire process shown in Figure 8-11 again because it must be authenticated at the new AP…During that time, the client must wait and any data flow already in progress will be disrupted—something that becomes very noticeable to voice and real-time applications. In other words, such a roam is not seamless at all.” on page 181, Chapter 8 in Cert Guide (300-425)
