An engineer needs to implement QOS mechanism on customer's network as some applications going over the internet are slower than others. Which two actions must the engineer perform when implementing…

To implement traffic shaping, a queue must be configured with sufficient memory to buffer packets that exceed the configured rate, holding them for later transmission instead of dropping them.

While token values are fundamental to policing and shaping mechanisms, they are typically configured as rates (bits per second) rather than explicitly as 'token values in bytes' in the context of setting up shaping policy.

Packet remarking changes the QoS classification of packets, which is a policing action or a marking action, not a direct component of the shaping mechanism itself that controls the output rate.

A scheduling function is essential in traffic shaping to manage the release of buffered packets over time, ensuring a smoothed output rate and handling packets that were temporarily delayed due to rate limiting.

Discarding excess packets based on a threshold is characteristic of traffic policing, which drops traffic exceeding a rate, whereas shaping buffers and delays it.
