How can the application developer troubleshoot the processing of the Possible Fraudevents?

Question16: A rule task includes rules that test on existence or collection items directly in working memory, and also makes use of dynamic priorities.
Which algorithm should the application developer set for this task?

Question17: While executing a RuleApp that has been deployed to the Rule Execution Server it becomes clear that the value of a ruleset output parameter has an unexpected result. It has been determined that the correct version of the RuleApp has been deployed to the Rule Execution Server and that monitoring has been turned on for the ruleset.
How can the application developer determine which rules in the ruleset executed on the Rule Execution Server?
From the Rule Execution Server console:

Question18: After a long period of inactivity, an execution request of the only ruleset deployed to Rule Execution Server is delayed.
Which change should the application developer make to avoid this problem?

Question19: An application developer needs to set up a new customer rule property whose value will be leveraged at runtime. Rules will be deployed from Decision Center.
How can the application developer do this?

What does the application developer need to do to completely diagnose this problem?

Question24: A company has multiple decision services that generate and send offers across various channels such as a Java based website as well as a COBOL based mailing system. The rules in these decision services may be different but they do use the same business vocabulary. The COBOL based mailing system requires native integration with the generated COBOL API stubs.
How must the application developer create their XOM(s) and generate their shared BOM(s)?

Question25: The business requires two rulesets and two ruleset signatures. Both ruleset signatures require a Loan object as one of the input parameters. The ruleset signatures are expected to act as follows:
1. "loan validation"; will only use rules in the Validation project.
2. "loan validation with pricing"; will use rules from both the Pricing project and the Validation project.
