IBM C9550-413 Value Pack (Frequently Bought Together)

An application developer needs to shrink the number of events being held in memory to reduce the memory footprint of the solution after an out-of-memory error. After reducing the event time horizon for events, agents, and aggregates, there is a problem with the accuracy of the aggregates.
Which combination of artifact definition and property values show the problem?

• A. Aggregate definition of:
  define 'total number test events' as the number of test events during the last period of 24 hours In the solution_properties.xml:
  <property name="eventAggregateMaxHorizon>PT36H
  </property>
• B. Aggregate definition of:
  define 'total number test events1 as the number of test events during the last period of 2 days In the solution_properties.xml:
  <property name="maxHorizon">PT12H</property>

After a long period of inactivity, an execution request of the only ruleset deployed to Rule Execution Server is delayed.
Which change should the application developer make to avoid this problem?

• A. Set the ruleset maxldleTime property.
• B. Increase the engine pool size.
• C. Activate asynchronous ruleset parsing.
• D. Increase the memory allocated to the server.

How can the application developer create new decision service rule projects and decision operations to maintain the ruleset signatures and BOM hierarchy as shown in the diagram?

• A. 1. Create a new Main rule project for the BOMs and a new Standard decision service project for the decision operations.
  2. Add BOM entries in the Main rule project for the Customers, the Orders and History and the Products.
  3. Add a BOM reference in the Customers entry to the Orders and History entry.
  4. Add a BOM reference in the Products entry to the Orders and History entry.
  5. Add all of the rules to the Main rule project.
  6. Create decision operations (one for customers, one for orders, and one for products) in the Standard Decision Service rule project.
• B. 1. Create a new Main rule project and three new Standard decision service projects to contain the BOMs (new BOM projects).
  2. Add project references in the Main rule project to all of the new BOM projects.
  3. Add a project reference in the new Customers BOM project to the new Orders and History BOM project.
  4. Add a project reference in the new Products BOM project to the new Orders and History BOM project.
  5. Add all of the rules and create decision operation in the Main rule project.
• C. 1. Create a new Main rule project.
  2. Add references from the Main rule project to Rule Project 1, Rule Project 2, and Rule Project 3.
  3. Create decision operations in the Main rule project.
• D. 1. Create a new Main rule project and three new Standard decision service projects to contain the BOMs (new BOM projects).
  2. Add project references in each of the new BOM projects to the Main rule project.
  3. Add ail of the rules to the Main rule project.
  4. Create decision operations in the Main rule project.

A rule task selects a package that contains the following rules:

The Priority property of those rules is set to the following values:
R1: 2
R2: 3
R3: 1
All three rules test the same object in their conditions and, at runtime, match instances of the object present in working memory. There is a requirement to have only instances of R1 fire in cases when more than one rule match.
Which rule task execution properties can the application developer use to meet this requirement?

• A. Fastpath algorithm, Literal ordering, and Rule Exit Criteria
• B. Fastpath algorithm, Default ordering, and Rulelnstance Exit Criteria

After analysis, following UIVIL diagram created to define object and their relationships.

Which business model definition should the application developer define to model all classes, attributes, and relationships from the diagram?

• A. an Aircraft Model can be one of: Airbus A380, Boeing_777.
  a Passenger is a business entity identified by an ID.
  a Passenger has an age (integer).
  an Aircraft is a concept with a model ( an Aircraft Model).
  a Pilot is a Passenger.
  a Pilot has some experienced aircrafts (Aircrafts ).
  a Customer is a Passenger.
  a Customer has a location (a point).
• B. an Aircraft Model is a concept with the values: Airbus A380, Boeing_777 a Passenger is a concept identified by an ID.
  a Passenger has an age (integer).
• C. an Aircraft Model can be one of: Airbus A380, Boeing_777.
  a Passenger is a business entity identified by an ID.
  a Passenger has an age (integer).
  an Aircraft is a concept with a moaei ( an Aircraft Moaei).
  a Pilot is a concept
  a Pilot has some experienced aircrafts (Aircrafts ).
  a Customer is a concept.
  a Customer has a location (a point).
