• BEnsure host scoped routing optimization is enabled.
• CEnsure PMI Workload Management counters are enabled.
• DEnsure each server in the cluster has an equal weighted value.
• EEnsure the Web server plug-in is using the round robin algorithm.

• A
  81% (52)
• B
  2% (1)
• C
  6% (4)
• E
  11% (7)

Explanation

A: Workload management optimizes the distribution of client processing tasks. Incoming work requests are distributed to the application servers, enterprise beans, servlets, and other objects that can most effectively process the requests. D: The server weighted round robin routing policy ensures a balanced routing distribution based on the set of server weights that have been assigned to the members of a cluster. For example, if all servers in the cluster have the same weight, the expected distribution for the cluster is that all servers receive the same number of requests. If the weights for the servers are not equal, the distribution mechanism sends more requests to the higher weight value servers than the lower weight value servers. The policy ensures the distribution that you want, based on the weights that are assigned to the cluster members.
