Designing Cisco Data Center Infrastructure (DCID) — Question 82
A network engineer must create a Fibre Channel fabric QoS design for an existing data center. The solution must provide relative bandwidth guarantees to application traffic, control latency, and prioritize application traffic.
Which mechanism must be deployed to support these requirements?
Answer options
- A. traffic policing
- B. traffic shaping
- C. traffic remarking
- D. traffic classification
Correct answer: B
Explanation
Traffic shaping is the correct choice because it allows for the control of data transmission rates, helping to ensure bandwidth guarantees and manage latency effectively. Traffic policing, while useful for enforcing bandwidth limits, does not provide the same level of guarantee for application traffic. Traffic remarking modifies the priority of packets but does not control their flow, and traffic classification focuses on categorizing traffic rather than managing its bandwidth.
