IBM InfoSphere Warehouse V9.5 Set 1

1.

After deploying an application, you might need to update it by making changes to one or more data flows. Deploying changes to an existing application is called delta deployment. How do you package changes using delta deployment?

Package only the operator or property that has changed. Package the data flow that has changed. Package the control flow. Package all the items that were originally packaged and use the same profile that was used.

2.

You are implementing a DB2 Workload Manager (WLM) schema to limit the number of load utilities that can execute concurrently. Which WLM object would be used to accomplish this?

work class with an associated work action and an appropriate threshold workload with an associated service class and an appropriate threshold work class with an associated service class and an appropriate threshold workload with an associated work action and an appropriate threshold

3.

Several operators are defined and linked together in DataFlow1. Another set of operators make up DataFlow2. A control flow is defined and both DataFlow1 and DataFlow2 are used. You require that DataFlow1 dynamically change the variable values used in DataFlow2. How can you fulfill this requirement?

The inherent design of the SQL Warehouse Tool is that any variable value changed in one data flow is accessible by any other data flow as long as the data flows are defined in the same warehouse project. Using the File Export operator, DataFlow1 writes a file that contains updated variable values. DataFlow2accesses those updated variable values by reading that same file using an Import File operator. When a control flow is executed, a run profile provides the initial values for all variables. Once those valuesare set in the run profile, they are in affect for the entire execution of the control flow. Using the File Export operator, DataFlow1 writes a file, containing updated variable values. A variable assignment operator is then used to assign the values in the file to the appropriate variables. DataFlow2 then has access to the updated variable values.

4.

Relational database and a database model that is often a star or snowflake schema are characteristics of which engine storage structure?

MOLAP ROLAP Multidimensional cubing Proprietary

5.

Every night, an InfoSphere Warehouse application updates data in a star schema in the data warehouse. The update process is taking longer than expected and so management decides to begin the update process at an earlier time each day. Which function of the Admin Console will accomplish this task?

Use Manage Processes Update. Use Manage Processes Disable, Update, and Enable. Use Manage Processes Schedules Update. Use Manage Processes Schedules Suspend and Update.

6.

OLAP metadata for a star schema has been defined in the Design Studio and exported as an XML document. Which step(s) are required to deploy the cube to a cube server?

Import the cube to the cubing services repository. Import the cube to the cubing services repository and associate the cube with a data source. Import the cube to the cubing services repository, associate the cube with a data source, and add it to acube server. Import the cube to the cubing services repository, associate the cube with a data source, add it to a cubeserver, and enable the cube.

7.

A warehouse application contains a process that in turn contains an activity that references a variable with a final phase of EXECUTION_INSTANCE. When going through the schedule wizard, which object is actually scheduled?

the process the activity a process profile the warehouse application

8.

Which section of the InfoSphere Warehouse Admin Console menu would be used to schedule an application?

Resources Common SQL Warehousing Processes

9.

Which two modeling techniques are similar in nature in performing prediction except for the type of the predicted value it uses? (For example, one predicts a class label, the other predicts a numeric value.) (Choose two.)

Regression Sequencing Associations Classification Clustering

10.

You need to join three tables together in a data flow. The Table Join operator is placed onto the work area and only has two input ports defined. Which technique should you use to join the three tables?

Use the SQL Merge operator to join all three tables. Add an additional input port to the Table Join operator. Use the Table Join operator to join two of the tables and then use the properties view to change thegenerated SQL. Use the Table Join operator to join two of the tables and then use a second Table Join operator to outer jointhe third.
