Which statement regarding decision services is true?

Question

Options

• AThe main rule project can be referenced by a XOM for purposes of exposing methods in
• BDecision services can be configured through parameters in the properties when rule
• CThe source rule project for the decision operation determines the rules, variables, and
• DWhen a decision service with multiple rule projects is published to Decision Center,

• A
  2% (1)
• B
  2% (1)
• C
  90% (43)
• D
  6% (3)

Explanation

Option C is correct because in IBM ODM (Operational Decision Manager), the source rule project tied to a decision operation is the authoritative source for which rules execute, what decision variables are available, and how the decision logic is structured - it defines the operational scope of that decision step.

Why the distractors are wrong:

• A reverses the relationship: the XOM (Execution Object Model) is referenced by the rule project to expose Java methods, not the other way around - a rule project depends on the XOM, not vice versa.
• B is incorrect because decision services are not configured through parameter properties at the rule project level; configuration and deployment settings are managed at the RuleApp/ruleset level or through Decision Center.
• D is incorrect in its implication about multi-project publishing - when a decision service with multiple rule projects is published, each project is packaged as a separate ruleset within the RuleApp, not merged or flattened.

Memory tip: Think "Source determines scope" - the Source rule project Shapes the Service's rules, variables, and logic. The three S's anchor option C as the structural truth about decision operations in ODM.
