Questions # 4:

After a decision service is implemented in the Rule Designer, a developer would like to analyze the rule artifacts in the rule project by creating a query in the fijle project. Which element can be found by the query?

Options:

Function

Rule task

Parameter

XOM class

Answer

Questions # 5:

A company wants to use ODM for asynchronous processing with large payloads and very strict performance guidelines. They want to keep data extraction and execution close to reduce any latency effects. They also need ODM to scale as they might want to execute rules from several different applications concurrently. What execution implementation fits these requirements?

Options:

A stand-alone POJO session on a single VM.

A custom MDB with a stateful or stateless rule session.

A J2SE rule session to create a tightly coupled application with performance gains.

An HTDS web service and increase the size of the connection pool based on performance testing needs.

Answer

Questions # 6:

A developer is working with a mainframe legacy application. How can they build the execution object model (XOM) with the information from this application?

Options:

Import the Cobol copybook.

Extract objects through SQL queries.

Use the Decision Engine API to map Cobol structures.

Use the Rule Designer migration tool to convert the source Cobol copybook.

Questions # 7:

A customer has an online and batch processing application. The batch process can be executed multiple times during the day on demand and can overlap the online application. RuleApps and rulesets are the same across online and batch. The batch application also manages big batches with high throughput.

How can this application be architected to address these requirements?

Options:

- Use an embedded approach for the online application and batch application to address the high throughput and change the execution units to file persistence to simplify the deployment.

- Separate infrastructure from online to batch, each one configured in a separate cluster.

- Configure a ruleset interceptor to route the workload between online application execution units and batch execution units.

- Configure 2 clusters in the same cell where the online application is running: one cluster for the online application and a second cluster for the batch process.

- Configure the Rule Execution Server console outside of the 2 clusters to share the RuleApps across the online and batch application.

- Use separate infrastructure for online and batch processing.

- Use managed approach with a centralized Rule Execution Server for online.

- Configure a set of J2SE RuIeApp clients to run in parallel and distribute the batch workload.

- Change the Rule Execution Server and XU notification mechanism to TCP/IP to use the same deployed RuleApps for both the batch and online application.

Answer

Questions # 8:

A customer needs to calculate sales taxes based on the state of origin for an online pricing solution. The customer identified 15 states in the US that have a different sales tax and also include 2-3 additional types of taxes. Also, these 15 states have different regulations and need to update taxes on a monthly basis.

How can a developer design the rule application to simplify the number of rules and the impact of multiple deployments so that unchanged rules are not duplicated?

Options:

- Organize tax rules in a common rule project to address taxes for the states sharing the same logic

- Create a separate rule project for every state where taxes calculations are unique

- Override common rules with unique rules from this separate rule project

- Create a rule project for every state to include its own tax rules

- Package all rule projects into a single RuleApp with multiple rulesets

- Create a rule project with only the rules of one state and use these rules as the only ruleset of a RuleApp

- Create a rule project with a single decision table with all states listed and the tax logic for every state in separate virtual methods from the BOM that can be used in the table.

- Use this rule project as the only ruleset in the RuleApp.

Answer

Questions # 9:

How would the following rule be classified?

The total insured value of the vehicle IS DEFINED AS the vehicle base value + Min (the value of vehicle accessories, 40% the vehicle base value)

Options:

Inference

Guideline

Constraint

Calculation

Answer

Questions # 10:
