Correct Response: C. QoS technologies are designed to ensure that high-priority traffic runs dependably even when network resources are limited. This is accomplished by allocating a higher priority to the most important data, such as video conferencing data. A is incorrect because QoS technologies do not manage network reliability. B is incorrect because QoS is responsible for data prioritization and not data compression. D is incorrect because QoS is involved with managing data traffic, and not with user authentication.
