The primary data center Interceptor is configured to fail-to-block. What best describes the result of stopping the Interceptor appliance service?

All traffic passes through the Interceptor appliance
The Interceptor allows UDP traffic to pass-through, but blocks all TCP traffic
Previously optimized connections continue to be redirected, but new TCP connections are passed through
All traffic through the Interceptor will be blocked
The Interceptor appliance communicates to the Steelhead appliances to disable their optimization service

Answer(s): D

Which statements are true regarding the default methods by which load-balancing takes place in the Interceptor appliance. (Select 2)

The Interceptor appliance uses round robin, for each TCP connection, regardless of source or destination IP address, and is equally load-balanced between a group of Steelhead appliances
The Interceptor appliance uses round robin, for each TCP connection, depending on source IP address, and is equally load-balanced between a group of Steelhead appliances
The Interceptor appliance uses hash assignment, for each TCP connection depending the hash value calculated from source and destination IP address, and is directed to a particular Steelhead appliance in the local cluster
The Interceptor appliance can dynamically determine and direct traffic for optimization to the least-loaded Steelhead appliances based on Steelhead appliance resource usage
The Interceptor appliance uses peer affinity, a Steelhead appliance in the local cluster that has been previously paired with a destination IP address is preferred
The Interceptor appliance uses peer affinity, a Steelhead appliance in the local cluster that has been previously paired with a remote Steelhead appliance is preferred

Answer(s): D,F

Which statement is true regarding “fair-peering”?

It is a default parameter
It enables load distributed using round-robin
It enables load distribution using peer affinity
It can be configured as part of a load-balancing rule
It automatically redistributes connections equally among all appliances in a cluster when a new appliance is added to the local cluster

Answer(s): D

Using an Interceptor appliance is an alternative to what network designs? (Select 2)

Answer(s): A,B

Provides a way to intercept and redirect interesting traffic for optimization
Monitors multiple links and redirect interesting traffic over a cluster of Steelhead appliances in a logical in-path deployment
Replaces any existing Layer 4 switch in a given environment
Used to configure and work with WCCP and PBR
Required component Steelhead appliances in all Steelhead appliance deployments

Answer(s): A,B
