Exam 300-420 topic 1 question 161 discussion

A - Shaping = Delays C - Shaping = Delays D - Rate - Limiting = Delays Answer B: is the correct answer, you use Bandwidth percentage to each subnet and Policing to cut off traffic. The answer never said we needed to worry about packet loss or packet drops when Link is congested.

Correct B

It cannot be shaping as traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time It cannot be Rate Limiting as well as it refer to both shaping and policing What is Rate Limiting? Network rate limiting is used to limit the amount of traffic on a network. There are two main methods of rate limiting: traffic policing and traffic shaping. Traffic policing measures the rate of incoming traffic and drops packets that exceed the maximum allowed rate.

It is C

"Download traffic must never experience a delay." This means we shouldn't be using Shaping at any point (since that puts packets into a buffer and sends them out later on when congestion has been reduced) Also: "Rate-limiting" is a bigger term and under it we have 2 things: "Policing" and "Shaping" So since Rate-limiting also refers to "shaping" we cannot go with that option B should be the correct answer
