The correct answer is C. The virtual server is in startup round robin mode. By default, a vServer enters "startup round robin" mode when it first comes up, distributing the first set of requests in round-robin to collect response-time metrics. Only after those initial probes does it switch to least-response-time balancing.

Load Balancing

Question

Scenario: A Citrix Administrator has configured an HTTP load-balancing virtual server with least response time as the load-balancing algorithm. The administrator notices that requests to the virtual server appear to be using the round robin load-balancing algorithm. What could be causing the virtual server to use the round robin load-balancing algorithm?

Options

  • AThe services that are bound to the HTTP virtual server are using the PING monitor.
  • BLeast response time CANNOT be used as a load-balancing algorithm on an HTTP virtual server.
  • CThe virtual server is in startup round robin mode.
  • DThe NetScaler configuration has NOT been saved yet.
