Question
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?
Options
- ADiffServ
- BRSVP
- CIntServ
- DWRED
Explanation
Guaranteed QoS: IntServ (Integrated Services) provides per-flow guarantees, which is ideal for business-critical, delay-sensitive, and high-bandwidth applications that need strict QoS. RSVP signaling: IntServ uses RSVP to reserve resources explicitly for each flow, ensuring the application receives the bandwidth and low delay it requires. High priority: IntServ is best suited when precise and strict QoS is needed, even though it may require more resources and isn't as scalable as DiffServ.
