Designing Cisco Enterprise Networks (ENSLD) — Question 244

An architect must design a QoS model for a business-critical application that is delay-sensitive and requires high bandwidth. The company’s head office hosts the application, and DMVPN tunnels protected with IPsec provide connectivity between the head office and branches. Which solution must the architect choose?

Answer options

Correct answer: A

Explanation

The correct answer is A, DiffServ, as it is designed to handle varying levels of service quality and is suitable for applications requiring high bandwidth and low latency. RSVP and IntServ are more suited for specific resource reservations rather than scalable solutions, and WRED is used for congestion management rather than QoS modeling.
