IBM WebSphere Operational Decision Management V8.0 Application Development 認定 C9550-400 試験問題:

1. An application developer collects the following requirements from the business analyst for the case assignment system:
-There are 4 sets of rules to be executed in successive tasks: initialization, preprocess, check
workload and assign case. -The initialization rules should be divided into 5 subsets and orchestrated with 1 ruleflow. -The assign case rules should be divided into 6 subsets and orchestrated with 1 ruleflow.
How should the application developer create the ruleflows?

A) Create 4 ruleflows, set the main flow task property of the main ruleflow to the name of the decision service and for each other ruleflow set it to the label of relevant rule task.
B) Create 5 ruleflows, set the main flow task property of the main ruleflow to the name of the ruleset and for each other ruleflow set it to name of the ruleflow.
C) Create 2 ruleflows and set the main flow task property of each ruleflow to true.
D) Create 3 ruleflows, set the main flow task property of the main ruleflow to true and set other ruleflows to false.

2. The Business Object Model (BOM) includes a Customer class with an Age attribute and a Score attribute both of type int. There are three rules and one query:

When the application developer runs Query 1, which rules will be returned?

A) Rule 2 and Rule 3
B) Rule 1 only
C) Rule 3 only
D) Rule 1 and Rule 2
E) Rule 2 only

3. A ruleset for validating the content of a message including cross-field validation and business range checking is ready to be integrated into an architecture with only a JVM container. The application must have the capability of providing to and removing from working memory any number of objects without resetting the rule session. Which execution approach should the application developer choose for this application integration?

A) Java SE with stateful rule session
B) POJO with stateful rule session
C) Java SE with stateless rule session
D) POJO with stateless rule session

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

5. A company is running 20,000 rules in one ruleset and experiences latency during some ruleset executions. No hot deployments are used. After reviewing the execution traces, the application developer recognizes that the performance is affected by reparsing of the same ruleset after overnight inactivity. What should the application developer do to minimize the impact of ruleset parsing and speed up performance?

A) Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
B) Make sure the cache is empty before the first ruleset is parsed.
C) In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
D) In the ra.xml file, set the pool.maxSize parameter to make sure that the number of active rulesets is greater than the size of the XU connection pool.
