Designing Cisco Enterprise Networks (ENSLD) — Question 89
A customer is discussing QoS requirements with a network consultant. The customer has specified that end-to-end path verification is a requirement. Which QoS solution meets this requirement?
Answer options
- A. IntServ model with RSVP to support the traffic flows
- B. DiffServ model with PHB to support the traffic flows
- C. marking traffic at the access layer with DSCP to support the traffic flows
- D. marking traffic at the access layer with CoS to support the traffic flows
Correct answer: A
Explanation
The correct answer is A, as the IntServ model with RSVP allows for end-to-end path verification and ensures that specific traffic flows are managed according to their requirements. The other options, while effective for traffic management, do not provide the necessary end-to-end verification needed to meet the customer's requirement.
