300-420 Question #199: Real Exam Question with Answer & Explanation

Question

An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements: - Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times. - A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle. - Download traffic must never experience a delay. Which solution must the architect choose?

Options

• Arate-limiting and shaping
• Bbandwidth percentage and policing
• Cshaping and policing
• Dbandwidth percentage and rate-limiting

Explanation

Shaping: Shaping is used to control the traffic flow by buffering excess packets during periods of high demand and then releasing them at a rate that conforms to the desired profile. In this case, shaping can be employed to ensure that each subnet receives no less than 10 Mbps during peak Policing: Policing is used to enforce traffic policies by discarding or remarking packets that exceed specified rate limits. In this scenario, policing can be employed to ensure that a subnet does not exceed its allocated bandwidth (40 Mbps) during non-peak times.
