B) Tracing cannot be enabled without deploying the ruleset again with the monitoring.enabled ruleset property set to true.
C) Navigate to the ruleset within Rule Execution Server console and click the Show Monitoring Options to enable tracing.
D) Use the res-deploy Ant task with the correct parameters to enable tracing on the deployed ruleset.

A) Project D
B) Project B
C) Project C
D) Project A

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

4. 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.

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

5. The response time of Decision Center while browsing and editing rule artifacts is slow. What should the application developer do to improve the performance?
