Dell EMC Specialist – Systems Administrator, VNX — Question 45

When implementing QoS on a 10Gb connection, 6Gb is required by the customer. What QoS level best fits the requirement while keeping resource use to a minimum?

Answer options

• A. Differentiated service
• B. Guaranteed service
• C. FIFO
• D. Best-effort service

Correct answer: B

Explanation

The correct answer is B, Guaranteed service, as it ensures a fixed bandwidth allocation, which meets the customer's 6Gb requirement while minimizing resource use. Options A and C do not provide the necessary guarantees for bandwidth, and option D, Best-effort service, does not prioritize traffic, making it unsuitable for the specific requirement.
