On many advanced routers and switches, you can implement QoS through bandwidth management, such as , where you control the flow of packets into or out of the network according to the type of packet or other rules.

a. port mirroring
b. trunking
c. traffic shaping
d. content switching

c. traffic shaping

Explanation:

A traffic shaping system is one that allows to adapt the incoming data traffic that comes from some node of the network giving it a special treatment called conformation of accepted traffic and thus allowing the frames to be forwarded through the network of data under traffic rules without having gone through some traffic shaping method, this can be detected as non-conforming traffic at the edge of access to the discarded metropolitan network.

Traffic shaping is a mechanism that alters the traffic characteristics of the cell flow of a connection to achieve better network efficiency while maintaining QoS objectives or in order to ensure that the cell flow conforms to traffic parameters according to the leaky bucket algorithm configuration of the traffic contract. Traffic shaping can be used in ATM, for example, to reduce peak speed, limit the length of the burst by means of adequate spacing of cells over time. The use and location of this function is network specific.
