QUESTION 1
What are two reasons for a combination of database and front-end tool based analytic
architectures in a data warehouse implementation? (Choose two.)

A. Less data is moved across the network, making queries run faster.
B. The database can provide consistent analytic calculations and query speed for common queries.
C. The combination of architectures will ensure fast query performance.
D. Multidimensional queries cannot be processed in SQL by the database engine so it must be done using a front-end tool.
E. The front-end tool allows for additional and more complex algorithms specific to applications that use that tool.

Answer: B,E

QUESTION 2
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?

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

Answer: C

QUESTION 3
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?

A. work class with an associated work action and an appropriate threshold
B. workload with an associated service class and an appropriate threshold
C. work class with an associated service class and an appropriate threshold
D. workload with an associated work action and an appropriate threshold

Answer: A

Explanation:

QUESTION 4
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?

A. 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.
B. Using the File Export operator, DataFlow1 writes a file that contains updated variable values.
DataFlow2 accesses those updated variable values by reading that same file using an Import File operator.
C. When a control flow is executed, a run profile provides the initial values for all variables. Once
those values are set in the run profile, they are in affect for the entire execution of the control flow.
D. 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.

Answer: D

QUESTION 5

characteristics of which engine storage structure?
