Refer to the exhibit. A Steelhead administrator has recently decided to implement two Interceptor appliances and one Steelhead appliance on his data center. After configuring the Intercetor appliances, and the Steelhead appliance, he decided to check if the devices will work appropriately. Which Intercetor appliance diagnostic tool did the administrator use?
A customer already has a SteelHead appliance in their datacenter and wants to add Steelhead Mobile. Their current deployment has their VPN gateway in parallel with their server-side SteelHead. The customer doesn’t want to interrupt VPN clients by moving the SteelHead in-path with the VPN gateway, so they will test using a fixed-target rule to the SteelHead in-path interface. Take a look at this diagram:
Will the client traffic be optimized to the server 192.168.1.10?
Which option below best describes the WCCP redirection supported by a SteelHead?
You have a pair of SteelHead appliances, both deployed in-path, both have a valid IP address on the in-path interfaces, optimizations are enabled and the service is started. They are unable to auto discover each other as a firewall is stripping the probes. How could you work around this on the SteelHeads?
The picture below corresponds to a connection using the SteelHead SaaS GeoDNS feature. What is the IP address of the closest Microsoft Exchange Client Access Server (CAS)?
You are troubleshooting a connection which is being passed-through. An in-path rule to optimize it is present, both SteelHeads are working and not in admission control. You examine the logs and find:
[intercept.WARN] asymmetric routing between 10.11.111.19:33262 and 10.11.25.23:5001 detected (no SYN/ACK)
What is the reason for the asymmetry?

Refer to the exhibit. A Steelhead administrator has decided to implement two Interceptor appliances and one Steelhead appliance on his data center. After configuring the Interceptor appliances, and the Steelhead appliance, he decided to check if the connections are being forwarded appropriately. What happened? (Select 2)
You plan to downgrade a SteelHead from RiOS v9.0.1 (Apr 17 2015) to 8.6.3 (Aug 7 2015). The appliance has not run v8.6.3 previously. Will this be successful?
You have a number of SteelHeads running RiOS 9.x. At each datacenter site, there are a cluster of domain controllers, one of which the SteelHead is connected to. As the volume of users on the network increase, the load which the server-side SteelHeads are placing on the connected domain controller pushes the domain to its limits, and authentication failures sometimes occur. What is the best way to address this?
True or False? To be able to use Active Directory assignments, the SteelCentral Controller for SteelHead Mobile must be joined to the domain.
Branch office users live streaming video URL fragment requests are not optimized even though Microsoft Silverlight stream splitting is enabled. What could be the causing this? (Select 3)
A customer with a new physical in-path installation decides to turn on the optimization service during lunch time on a working day. This is done so that he can see if the users perceive any performance improvement. When starting the optimization service, he does not enable the in-path kickoff option. Assuming there were several already active connections when he starts the optimization service, how will the Steelhead appliances handle these existing connections?
What interface on the CMC appliance is required for the initial configuration?
How many versions of CMC appliance software images can reside on the CMC simultaneously?
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
WCCP protocol has a methodology of load balancing with two or more Steelhead appliances. What are the maximum number of buckets able to be used for the MASK assignment?
In an in-path deployment, if a naked SYN packet arrives on the WAN interface of Steelhead, what probe option is added to this SYN packet for auto-discovery?
To increase the high availability of a site at a remote office, you decided to install a second Steelhead appliance as an active/active serial cluster. However, after installing the second Steelhead appliance at the remote site, users started complaining about slow access to the data center. You have verified that this is not a duplex issue. At the data center location all users access the Internet which pass-through the Steelhead appliances. What is the most likely problem?

In a new in-path deployment, connections are listed as pass-through on the branch office Steelhead appliance. Which of the following is the likely cause of the problem?
1) Pass-through rule preventing optimization
2) Server-side Steelhead appliance is down
3) Satellite proxy not copying auto-discovery probes
4) Asymmetric routing is detected for the client/server flow
5) Duplex mismatch on WAN or LAN interface
