Designing Cisco Enterprise Networks (ENSLD) — Question 132

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?

Answer options

Correct answer: B

Explanation

The correct answer is B, as bandwidth percentage and policing allow each subnet to maintain a minimum bandwidth guarantee while also enabling excess usage during non-peak times. Options A and C do not adequately ensure the minimum bandwidth requirement under peak load conditions, while option D does not provide the necessary policing needed to manage bandwidth effectively.
