In a DataPower environment, which of the following best describes the relationship between a policy and the messages it processes?
A policy is a static configuration that does not change.
A policy can only apply to messages of one specific type.
A policy defines rules that dynamically adjust based on message content.
A policy is unrelated to the processing of messages. Answer: C
nation: A policy defines rules that can dynamically adjust based on the content and attributes ges being processed, allowing for flexible message handling.
