In a serial cluster deployment of Interceptor appliances, which interfaces are connected from one Interceptor appliance to another Interceptor appliance assuming they are connected back to back?
A customer's network consists of a data center with an Interceptor appliance and a Steelhead appliance cluster and several remote sites each with Steelhead appliances.
You would like to pass-through an application unoptimized due to a suspected problem and are provided the following information:
The application uses a static TCP port, 15000.
The application is initiated from the remote site machines.
The same servers which host the application host several other applications as well.
Based on the information provided which option will allow the application to pass-through:
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:

A server-side logical in-path deployment is shown in the exhibit. Additionally, SH12 is configured with a fixed-target rule pointing to SH11. The client behind SH12 will not be able to establish a connection to SERVER1 as a logical loop will occur when the number of optimized connections in SH11 has reached the maximum system limit.

In order to achieve optimization using auto-discovery for traffic coming from site C and destined to site A in the exhibit, which configuration below would be required?

What is the process for dropping the connection of an individual user that is currently being optimized? As an example, consider an HTTP connection being optimized with a local address of 192.168.5.10 and remote address of 192.168.5.90. (Select 2)
On the Interceptor appliance, the Networking > Steelheads page displays which of the following?
To prevent possible denial of service attack, such as TCP SYN flooding, which of the following features could be used?
The default setting for “allow failure” in the Interceptor appliance version 2.0 is: (Select 2)
In the exhibit,
Client41 and Client42 have full access to the HTTP and FTP services provided by Server31 and Server32 respectively. They continue to have access to these servers after SH3 and SH4 are deployed. A quick check on SH3 and SH4 registers the connections from Client41 and Client 42 as pass-through traffic. Note that SH3 and SH4 are in auto-discovery mode. What are the likely causes? (Select 2)
Refer to the exhibit.
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)
Which two of the following attributes are required to be added to a TACACS+ server to enable monitor and admin logon access to the CMC appliance via TACACS: (Select 2)
What types of operations can be observed under the Manage > Operation History page in the CMC Management Console? (Select 2)
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?
While looking at the Current Connections page on a client-side Steelhead, you noticed that there is more CIFS traffic on the WAN than on the LAN for some connections. What may be the problem?
1) The source data is compressed or encrypted
2) File server not located on the same subnet as the server-side Steelhead
3) The Steelhead is counting both CIFS optimized and unoptimized traffic
4) CIFS read-ahead
5) CIFS write-behind
The port used by the Steelhead appliance for datastore synchronizations is:
What is the default CMC appliance name resolved by the Steelhead appliance for initial configuration?
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?
