• Question 66:

  Scenario: An administrator introduced two new servers into a server farm; the servers can handle more traffic than the older servers. The current load balancing method set for the virtual server managing the traffic for this group of servers is least connections. The administrator wants to maintain that load balancing method but also wants to use the new servers to improve performance by sending more traffic to them than to the older servers.

  Which advanced option must the administrator configure to achieve this?

  A. Max Client
  B. Service Weights
  C. Backup virtual server
  D. Global Setting Override
  E. Connection-based Spillover
  B. Service Weights

  A. When USNIP is configured
  B. In a single subnet configuration
  C. In a two-arm mode configuration
  D. When USIP is configured for services
  D. When USIP is configured for services

• Question 68:

  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. All servers are in the same web farm.

  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.

• Question 69:
