Question 1

The Java method Customer.getLastOrderAmt() is verbalized as last order amt} of {this}? and returns the amount of the last customer order. The rule authors decided that ?amt? should be spelled out as ?amount? in rule artifacts. Many rule artifacts already exist using the ?amt? abbreviation. To address the new requirement, the application developer should:

A. use Alt+Shift+R from a rule editor to rename ?amt? to ?amount? and apply refactoring to the rule artifacts.

B. rename the Business Object Model (BOM) method and perform a BOM update to refactor the rule projects.

C. edit the subject used in the verbalization and apply refactoring to the rules.

D. use a semantic query with an action to refactor the rule artifacts.

Correct Answer: C

Question 2

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. An attribute private int age;

B. A method protected int getAge();

C. A method public int getAge();

D. A method private int getAge();

Correct Answer: C

Question 3

The business users require the ability to maintain Business Object Model (BOM) domains using the Decision Center. To address this requirement, the application developer should create:

A. domains of static references.

B. domains of bounded type.

C. domains from Excel files.

D. domains of collection type.

Correct Answer: C

Question 4

A retail company needs a monthly report that lists only decision tables from all their pricing projects. The business users tried using queries to generate the report, but were unable to capture everything they need into an easy-to-read format, so they asked an application developer for help. What can the application developer do to support this requirement?

A. Design a custom report template in Rule Designer with BIRT templates, and publish the report to Decision Center.

B. Define a ruleset extractor that extracts the correct set of decision tables, and publish the extractor to Decision Center.

C. Design a custom report template in Rule Designer with BIRT templates, then package the BIRT web application with Decision Center libraries.

D. Use the Decision Center Options menu to set additional options so that the report will automatically include those options each time it is generated.

Correct Answer: C

Question 5

An application developer is in charge of synchronizing changes in a rule project between Decision Center and the Source Code Control (SCC) tool used for development. Which rule project artifacts should the application developer exclude from SCC?

A. output folder and .syncEntries file

B. resources and templates folders

C. output, templates and queries folders

D. resources folder and .syncEntries file

Correct Answer: A

Question 6

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. RetePlus and check "Update object state" on BOM members as needed

B. Fastpath and implement a loop construct in the ruleflow

C. Fastpath and check "Update object state" on BOM members as needed

D. Sequential and implement a loop construct in the ruleflow

Correct Answer: A
