The exhibit shows a data center side serial clustering deployment. In this organization, not every remote site has a Steelhead appliance deployed, and all remote locations will be connecting to the data center.
For connections initiated from the data center, there is a possibility that the Steelhead appliances shown in the exhibit will end up peering with each other, rather than the intended remote Steelhead appliances. Where are peering rules needed to prevent this problem?
Refer to the exhibit.
In the accompanying exhibit, SH3 and SH4 are able to optimize FTP and HTTP sessions between Client41 and the respective application hosts Server31 and Server32. However, optimization does not happen for Client42 and these application hosts. A quick check on SH3 and SH4 registers neither optimized nor pass-through traffic from Client42. Client42 is able to ping Client41 and the in-path address of SH4. Note that SH3 and SH4 are in auto-discovery mode. What is the likely cause?

SH3 and SH4 are able to optimize FTP and HTTP sessions between Client41 and the respective application hosts Server31 and Server32. However, optimization seems to be a problem for Client42 and these application hosts. A quick check on SH3 and SH4 registers neither optimized nor pass-through traffic from Client42. Client42 is able to ping to both Server31 and Server32. Note that SH3 and SH4 are in auto-discovery mode. What is the likely cause?

Traffic going from Corp-A-DC-2 towards Corp-B will always use Link-1. Traffic from Corp-B back to Corp-A-DC-1 may traverse Corp-A-DC-1, over the GigaMAN before it reaches Corp-A-DC-2. No TCP connections are initiated from Corp-B to either Corp-A-DC-1 or Corp-A-DC-2. Unfortunately, the customer does not have any money to purchase any additional Steelheads. What are some possible fixes to ensure optimization occurs while Link-1 is operational? (If Link-1 ceases to function, optimization is not possible.) (Select 2)

Two Steelhead appliances deployed in-path at different offices cannot auto-discover each other. What technique can be used to “force” the two Steelhead appliances to optimize traffic between each other?
A firewall at a remote site on the WAN side of Steelhead appliance (A) is stripping out the 76 and 78 values in the TCP options field. Steelhead appliance (B) is in the local cluster of appliances communicating with an Interceptor appliance. The desired result is for optimization to continue between Steelhead appliance (A) and Steelhead appliance (B) for all traffic originating from the remote site. A suggestion is made to use fixed target rule(s) to meet this objective. Based on the information provided select the best answer from the choices below:

For a new connection, a Load Balancing rule matches but none of the target Steelhead appliances in the rule are available. What will happen to the new connection?
A data center location has three Steelhead appliances and one Interceptor appliance clustered together. If Steelheads A and B are unable to handle the new web traffic on port 80, the administrator does not want the connection to be serviced by Steelhead C. Given the current rules, we want to prevent traffic from redirecting to Steelhead C.
Current Rules:
Rule 1: Redirect rule for ports 445, 139, 80, target SH A
Rule 2: Redirect rule for ports 8080, 80, target SH B
Auto (default rule)
Which rule should be added on the Interceptor to achieve desired functionality?
What deployment type supports fail-to-wire?
A customer with no Steelhead appliances currently deployed wants to test Steelhead Mobile on a client that connects to corporate through a VPN over the Internet. The customer has the requirement that there be no network disruptions during the initial testing phase. Which of the following would work?
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?
