A SteelHead is running RiOS v8.6 and has an inpath0_0 IP address of 192.168.1.10. It is later upgraded from v8.6 to v9.0. As part of an IT project, the inpath0_0 IP address is changed to 10.10.10.10 and the configuration saved. Some time passes and the administrator decides to revert to RiOS v 8.6. It hasn’t been factory reset. The appliance boots and the Management Console User Interface is reachable, however, optimization no longer works. What has happened?

You plan to downgrade a SteelHead from RiOS v9.0.1 (Apr 17 2015) to 8.6.3 (Aug 7 2015). The appliance was previously running v8.6.3 but was factory reset after the upgrade. Will this be successful?
You have an in-house HTTP application running on port 8443 but you are not seeing HTTP optimization. You checked and made sure that the HTTP blade is enabled. What is the likely problem?
Refer to the exhibit.
SH3 and SH4 are able to optimize HTTP sessions from Client41 to application host Server31. However, Client41 receives a failure messagE. “ftp connect: Unknown error number” while trying to connect Server32. The same applies to Client42. Note that SH3 and SH4 are in auto-discovery mode. Client41 and Client42 are able to ping Server32. What is the most likely cause of this failure?

If using Fixed-target rules, what Steelhead specific probe options are associated with the SYN packet?
A Windows Vista client tries to download a file from a Windows 2008 server over a 45Mbps link with 200ms. Assuming the connection is optimized, given the default configuration on the Steelhead, what optimization techniques would be applied?
1) Data Streamlining
2) Transport Streamlining
3) MS-SQL Transaction Prediction
4) HighSpeed TCP
5) MX-TCP
Refer to the exhibit.
A customer is reporting that the first connection from a user to the server is failing. However, subsequent connections work properly and are optimized. How can this problem best be resolved?
