Refer to the exhibit.
A customer has a server-side out-of-path deployment, and reports that connections from some of their remote branch offices are not being optimized. What is the most likely problem?
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?
A customer wants to mark the IP precedence value for a passive FTP data connection as flash (flash = CS3). Which of the following are true? (Hint: Use the calculator)
What differences are there between upgrading an active VSP configuration from Steelhead EX v1.0 to Steelhead vEX 2.0 and installing a fresh Steelhead EX v2.0 appliance? (Select 2)
Refer to the exhibit.
Assume that a packet being optimized by SH10 incorrectly ends up on SH11 (due to load balancing error, or similar). How can you ensure that this packet is correctly returned to SH10?
Company X has many offshore oil rigs they want to bring optimization to. The only available connection is through a satellite that has frequent bursts of packet loss. There are very few users per rig and HTTPS-based SharePoint performance is so poor they often time out pulling down even a small file. CIFS often does not work at all. They are considering the Steelhead Mobile solution to solve this problem. You suggest they deploy a Steelhead in-path at the data center and:
Why should you use promiscuous mode on each in-path virtual NIC for Virtual Steelhead appliance? (Select 2)
One of the Steelhead appliances in your Steelhead appliance cluster is running an older version of RiOS. You decide to schedule a change window to upgrade that Steelhead appliance's image to the current release. What should you do to ensure that the Steelhead appliance optimization still occurs and the upgraded Steelhead appliance no longer accepts new connections?
Refer to the exhibit.
If Steelhead Mobile Client B offers up a share on the network, what is needed on Steelhead Mobile Client R to open an optimized connection to this share if enhanced auto-discovery is enabled on all Steelhead appliances?
A customer would like to deploy the Interceptor appliance on four aggregated 100 Mbps links which use LACP to bundle the physical links into a single logical link. Which of the following is true? (Select 2)
The Interceptor appliance can be configured to redirect traffic to the Steelhead appliances via what methods?
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:
On the Steelhead Mobile Controller, what VPNs require the use of Reorder Intermediate Drivers? (Select 2)
Which of the following are configurable attributes of an Interceptor appliance? (Select 3)
The primary data center Interceptor is configured to fail-to-block. What best describes the result of stopping the Interceptor appliance service?
Refer to the exhibit.
You configured CIFS prepopulation at Corp-A but it is not working. What is likely the cause of the issue?
Which hypervisor platforms are officially supported by Virtual SteelHead? (Choose three.)
Consider a SteelHead deployment with SMB optimization and SMB signing enabled on all SteelHeads. The client is configured to have signing enabled and the server has signing disabled. What will happen to SMB connections between these two hosts?
A customer wants to optimize traffic from remote VPN sites to DMZ servers in the data center shown in the accompanying exhibit.
The customer would also like to deploy their data center Steelhead appliance in a way that would allow them to keep transparency to the LAN servers, and allow the LAN servers to initiate optimized connections to remote sites. The current network architecture can satisfy these requirements by using which following deployment method?
A single client-server TCP connection is made through two Steelhead appliances (default in-path deployment). This is a lab-controlled environment and no other client-server connections are made. How many TCP connections will exist between the in-path interfaces of both Steelhead appliances after the user connection is fully established?
In an implementation using a 4-port card, which interface could be used as the Connection Forwarding neighbor? (Select 2)
Which of the following IP addressable interfaces can be connected for management purposes?
1) WAN
2) LAN
3) Primary
4) AUX
5) In-path

To prevent possible denial of service attack, such as TCP SYN flooding, which of the following features could be used?
What is contained in the probe of the return SYN/ACK packet when using enhanced auto-discovery (EAD)?
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?
