Quality of service (QoS) is a technology that allows a network design to strategically optimize network performance for select traffic types. This means, using QoS on a network device can identify which traffic types need to be sent first, how much bandwidth to allocate to various traffic types, which traffic types should be dropped first in the event of congestion, and how to make the most
efficient use of the relatively limited bandwidth of an IP WAN.
Indicate whether the statement is true or false
TRUE
Explanation: Quality of service (QoS) is a suite of technologies that enable you to strategically optimize network performance for select traffic types. For example, in today's converged networks (that is, networks simultaneously transporting voice, video, and data), some applications (for example, voice) might be more intolerant of delay (that is, latency) than other applications (for example, an FTP file transfer is less latency sensitive than a Voice over IP [VoIP] call). Fortunately, through the use of QoS technologies, you can identify which traffic types need to be sent first, how much bandwidth to allocate to various traffic types, which traffic types should be dropped first in the event of congestion, and how to make the most efficient use of the relatively limited bandwidth of an IP WAN.
