• Question 121:

  Once a SteelHead is registered for Cloud (SaaS) optimization it contacts the Cloud portal every 5 minutes to receive the latest information about the service. What would happen if a Firewall change stops the HTTPS communication with the Portal?

  A. The Cloud optimization stops working after 5 minutes
  B. The Cloud optimization continues to work with the last information received from the Portal
  C. The SteelHead will try HTTP (port 80) to contact the Portal once it sees no response using 443
  D. The Cloud optimization Service cannot redirect traffic because DNS resolution is performed through Primary interface
  D. The Cloud optimization Service cannot redirect traffic because DNS resolution is performed through Primary interface

• Question 124:

  Refer to the HTTP trace exhibit.

  

  You noticed in the HTTP reports that you are not seeing any hits. What is required in order for HTTP optimization to work?

  A. Client request is missing the "Cache" header
  B. Keep-alive timeout on the server it too short
  C. Server does not support HTTP 1.1 extensions

• Question 125:

  You are configuring HighSpeed TCP in an environment with an OC-3 (155Mb/s) and 60 milliseconds of round-trip latency. You know that the rule of thumb is to set the Steelhead appliance's WAN Default Send Buffer Size and WAN Default Receive Buffer Size to 2*BDP for the link. The buffer size setting for this link would be closest to: (Hint: Use the calculator)

  A. 4,665,000 bytes

• Question 127:

  Which of the following methods can be used to reduce the load on a router configured to use outbound interface WCCP redirection? (Select 3)

  A. Using inbound interface redirection instead
  B. Use fixed-target rules and remove WCCP on the WAN facing interfaces
  C. Use Redirect lists to control what traffic gets redirected
  D. Use the router command "load interval 30" to restrict WCCP to use 30% of the CPU
  E. Use Event Element Manager (EEM) to load balance between a clustered Steelhead appliance deployment
  A. Using inbound interface redirection instead
  B. Use fixed-target rules and remove WCCP on the WAN facing interfaces
  C. Use Redirect lists to control what traffic gets redirected

• Question 128:

  You are troubleshooting a TCP connection that is not being optimized. On the Current Connections report, you expand the connection and see the pass-through reason is `Pre-existing connection'. Without restarting the oprimization service, how could you get this connection to optimize?

  A. Reset the connection in the Current Connections report.
  B. Create a full-transparency in-path rule for the source and destination hosts.
  C. Create a fixed-target in-path rule for the source and destination hosts.
  D. Enable auto-kick-off on the default in-path rule.
  E. Enable Simplified Routing in `all' mode.
  A. Reset the connection in the Current Connections report.

• Question 129:

  Given four Steelheads are deployed in a WCCP cluster and all Steelheads are optimizing traffic to and from the data center. Steelhead-A fails and only Steelhead-B and Steelhead-C are intercepting new connections while Steelhead-D is NOT optimizing any traffic. What is the likely problem?

  A. The load balancing algorithm on the router is broken
  B. Simplified routing is not enabled
  C. Steelhead-B and Steelhead-C are missing the "in-path neighbor continue-intercept" command
  D. Steelhead-D is missing the "in-path neighbor allow-failure" command
  E. Need to issue the command "in-path accept connections" on Steelhead-D
  D. Steelhead-D is missing the "in-path neighbor allow-failure" command

• Question 130:

  The primary data center Interceptor is configured to fail-to-block. What best describes the result of stopping the Interceptor appliance service?

  A. All traffic passes through the Interceptor appliance
  B. The Interceptor allows UDP traffic to pass-through, but blocks all TCP traffic
  C. Previously optimized connections continue to be redirected, but new TCP connections are passed through
  D. All traffic through the Interceptor will be blocked
  E. The Interceptor appliance communicates to the Steelhead appliances to disable their optimization service
  D. All traffic through the Interceptor will be blocked
