• Question 51:

  Scenario: A banking company plans to use their NetScaler system to improve their site performance. They will use NetScaler to direct traffic to different servers so that users accessing the mortgage page go to one set of servers, users accessing the banking page go to a second set of servers, users applying for a student loan go to a third set of servers and all other traffic goes to the home page. The administrator has already enabled the necessary features and bound the appropriate services to the load balancing virtual servers. In which order could the administrator perform the actions to define a content switching virtual server to meet these requirements?

  A. Add the content switching virtual server, add the default policy and add the other policies; then bind the load balancing virtual server and policy to the content switching virtual server; then bind the default load balancing virtual server to the content switching virtual server with the default policy.

  B. Add the content switching virtual server, bind the load balancing virtual server to the content switching virtual server, add a policy and bind the policy to the load balancing virtual server; then bind the default load balancing virtual server to the content switching virtual server without associating a policy.

  C. Add the policy, add the default policy, bind the policy to the load balancing virtual server, add the content switching virtual server, bind the load balancing virtual server to the content switching virtual server; then bind the default load balancing virtual server to the content switching virtual server with the default policy.

  D. Add the named expressions, create the appropriate content switching policy and add the content switching virtual server; bind the load balancing virtual server and policy to the content switching virtual server and then bind the default load balancing virtual server to the content switching virtual server without associating a policy.

  Correct Answer: D

• Question 52:

  Scenario: An events ticketing company plans to use the content switching feature of NetScaler to parse traffic so that users purchasing tickets or answering surveys go to group A servers, users accessing images go to either group B or C servers depending on the ticket category and all other traffic goes to group D.

  Which two actions must an administrator perform to correctly define the content switching virtual server so that traffic NOT going to groups A - C gets directed to group D? (Choose two.)

  A. Bind a load balancing virtual server to the appropriate service for the web farm.

  B. Bind the appropriate service to a load balancing virtual server for serving content group D.

  C. Bind the appropriate load balancing virtual server to the content switching virtual server without a policy.
