An application developer needs to create a read-only attribute age in the Business Object Model (BOM) member Customer . The BOM uses a Java Execution Object Model (XOM). What should the application developer add to the XOM member that maps to the BOM member Customer?

• A. A method protected int getAge();
• B. A method public int getAge();
• C. A method private int getAge();
• D. An attribute private int age;

The rule 'NewYearDiscount' was introduced to apply a 30% discount based on quantity purchased and coupon code for the store items with id 1000, 1001 and 1002. The IRL for the rule is as follows:

What should the application developer do?

• A. Fix the ruleset invocation code to pass non-null Order and LineItem instances.
• B. Fix the implementation of the LineItem.toString() method to handle null cases.
• C. Initialize LineItem instances with a default non-null coupon code.
• D. Initialize LineItem instances with a default quantity and ID.

A rule task associated with 10 action rules performs elaborate computations on a set of objects. The action part of the rules changes the state of the objects involved in the conditions so that the firing of one rule may cause another rule to fire. For the computation to be correct, the firing of rules should continue until there are no more rules eligible to fire. How should the application developer implement this requirement? Set the rule task algorithm to:

• A. Sequential and implement a loop construct in the ruleflow
• B. Fastpath and implement a loop construct in the ruleflow
• C. RetePlus and check "Update object state" on BOM members as needed
• D. Fastpath and check "Update object state" on BOM members as needed

Within a pricing application, there are three valid regions: A, B, and C.
The pricing rules currently include this decision table. The current version of this table has a gap in the rules and does not assign a discount for Gold customers in region C.
To prevent this rule from getting deployed in the future, gaps for this decision table should be treated as an error.

What should the application developer do in Rule Designer to treat gaps as an error condition within this decision table?

• A. From the decision tables properties, turn on gap checking for all condition columns and enforce locking for this table.
• B. From the general tab, update the preconditions section with gapChecking=true;
• C. From the column condition builder, turn on check interval for each condition column.
• D. From the decision tables properties, turn on gap checking for all condition columns and set the reporting of gaps to an error level.
