• Question 351:

  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:

  A. Configure in-path rules on the Interceptor appliance to pass-through destination TCP port 15000

  B. Configure in-path rules on the data center Steelhead appliances to pass-through the server IP addresses

  C. Configure a peering rule on the Interceptor appliance to pass-through destination TCP port 15000

  D. Configure a load-balancing rule on the Interceptor appliance to pass-through destination TCP port 15000

  E. Stop the Interceptor appliance service

  Correct Answer: D

• Question 352:

  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:

  A. On Steelhead appliance (A) configure a fixed-target rule to the Interceptor in-path address

  B. On Steelhead appliance (A) configure a fixed target rule to the Interceptor in-path address with Steelhead appliance (B) as the backup target.

  C. On Steelhead appliance (A) configure a fixed target rule to the Steelhead appliance (B) in-path address

  D. Fixed target rules will not work with Steelhead appliances virtually out of path and communicating with Interceptors

  E. TCP option 76 or 78 are not relevant when an Interceptor appliance is used, Peer Affinity will automatically achieve this objective

  Correct Answer: C
