NEW QUESTION # 105
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?
- A. bandwidth percentage and policing
- B. shaping and policing
- C. bandwidth percentage and rate-limiting
- D. rate-limiting and shaping
Answer: A
Explanation:
Selected answer: B
"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"
NEW QUESTION # 106
