Questions # 44:

A customer requested that a guaranteed service line be enabled for a manufacturing business in different countries. On the customer side, the QoS-aware application is used to process large data chunks. The application cannot tolerate drops and latency should be as low as possible. Which QoS model must an engineer employ to use the minimum required resources on the ISP network nodes?

Options:

A.

Implement a group-based QoS strategy with FECs enabled

B.

Enable a flow-based QoS strategy with queuing elements.

C.

Implement an end-to-end QoS strategy with SLA.

D.

Configure a domain-based QoS strategy with PHB behavior.
