Scenario: An administrator is trying to improve site security by using the content filtering feature to terminate a client connection when it detects a possible instance of nimda virus. The administrator has already created a policy expression that will match traffic with ROOT.EXE or CMD. EXE and plans to use the RST action to terminate the appropriate connections. How can the administrator associate the policy expression and action to achieve the desired result?

Scenario: A banking company plans to use their NetScaler system to improve their site performance by having it parse 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 pages 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 an administrator perform the actions to define a Content Switching virtual server to meet these requirements?
Add the named expressions, add a policy with the expressions, 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.

Which method should be used to load balance Intrusion Detection System servers for optimal distribution?
Source IP/Destination IP Hash
Scenario: An administrator is creating services for servers in a farm where the IP addresses do not change rapidly. The administrator plans to use the NetScaler system to forward encrypted traffic to server1, server2, and server3 so that the traffic goes to the back-end web server without decryption. The IP addresses for server1, server2 and server3 are 220.127.116.11-3 and all servers are listening on port 443. The service for encrypted traffic is named "encrypted." The administrator will load balance these servers. How can the administrator create the service through the command line interface for this scenario?

Scenario: An administrator has created a policy expression to identify URLs with a cascaded style sheets (CSS) suffix. The administrator plans to use the policy expression to prevent URLs with a CSS suffix from being compressed when the HTTP response is received. How can the administrator associate the policy expression and action to achieve the desired result?
Add a compression policy with the policy expression and action specified, then bind the policy with the appropriate priority.
