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.

Answer:A. True.

Explanation:Quality of service (QoS) is a term in networking which means the ability of any technology to make decisions regarding traffic priorities,in order to control and ensure reduced or no losses in packet data, jitters, bandwidth and latencies in the network.

In today's convergent evolutions in networking, Quality of service (QoS) is of great necessity to especially high Network users to protect and help them achieve high productivity with reduced losses.

Answer:

A. True

Explanation:

QOS or quality of service is a technique used in information technology, to give priority to a protocol or a group of protocols. It is applicable only in the recent convergent networks.

It provides selected or prioritized protocols with network link access before other protocols. For example, it is used in VoIP phones to communicate at a high bandwidth higher than packet transmission.
