After installing a Steelhead appliance at a remote site, users started complaining about some optimized
applications being slower. After some initial investigating, you discovered a backup job was consuming most of
the bandwidth causing congestion. You also found that QoS is configured on the router and should have
prevented this but it did not. What is the most likely cause?

A.
Simplified routing is not enable on the remote Steelhead appliance.

B.
Simplified routing is not enable on the data center Steelhead appliance.

C.
Asymmetric routing.

D.
QoS on the router identifies traffic using destination IP and ports while the Steelheads are configured to
use correct addressing.

E.
QoS on the router identifies traffic using destination IP and ports while the Steelheads are configured to
use full transparency.
