   A pool of application servers is configured with the Least Connections load balancing method. The administrator notices that one server is receiving a disproportionate share of traffic. Upon investigation, it is discovered that this server has a much higher connection timeout, causing connections to remain active longer. What is the most effective way to address this imbalance?

   • AConfigure a health monitor that checks connection timeout and marks the server down if it is too high.
   • BChange the load balancing method to Round Robin to distribute new connections evenly regardless of connection duration.
   • CSet a lower connection limit on the server with the high timeout.
   • DInvestigate why the server has a higher connection timeout and fix the server configuration to match the others.

   A company has a pool of three servers. Server A is a powerful new machine, Server B is an older but adequate machine, and Server C is a legacy machine that should only be used if both A and B are unavailable. The administrator wants to distribute traffic primarily to Server A, with Server B handling overflow, and Server C as a last resort. Which configuration achieves this?

   • AConfigure Least Connections and set a connection limit of 0 for Server C.
   • BConfigure Priority Group Activation with Server A in priority 1, Server B in priority 2, and Server C in priority 3, with no load balancing method.
   • CConfigure Ratio (member) with weights of 3 for Server A, 1 for Server B, and 0 for Server C, and enable Priority Group Activation.
   • DConfigure Round Robin and rely on the health monitor to remove Server C when it is not needed.

   A pool of four servers runs a critical application. The administrator has configured a health monitor that checks the application's HTTP endpoint every 5 seconds. The monitor is set to mark a server down after 3 consecutive failures. A server begins to fail intermittently, failing one check, then passing the next, then failing again. What is the impact on traffic distribution?

   • AThe server will receive traffic only when it passes a health check, and will be excluded between failures.
   • BThe server will continue to receive traffic because it never reaches the 3 consecutive failures required to be marked down.
   • CThe server will be marked down after the first failure and will be immediately removed from the pool.
   • DThe server will be marked down after the first failure and will not receive traffic until it passes 3 consecutive checks.
