1. The default port types for the ports in the Joiner Transformation after adding the Master and Detail sources

a. Input b. Input/Outputc. Input for Master Source and Output for Detail Sourced. Input for Detail Source and Output for Master Source

2. The Joiner Transformation supports

a. Equivalent Joinsb. Non-Equivalent Joinsc. Bothd. Depends on the number of Joiner Transformations used in the mappings.

3. Joiner Transformation cannot be used in which of the following situations

a. In joining a Relational and an XML sourcesb. Both input pipelines originate from the same original data sourcec. In joining a csv text file and an XML Sourcesd. Both input pipelines originate from the same Source Qualifier

Transformation

4. When a Joiner transformation occurs in a session, the Informatica Server reads all the records from the

a. detail source and builds index and data caches based on the detail rowsb. master source and builds index and data caches based on the master rowsc. can be configured in the session properties to either use detail or master source to

build index and data caches d. depends on which source the Informatica Server first reads

5. Both Filter and Joiner Transformations are

a. Passive/Connectedb. Active/Connectedc. Passive/Unconnectedd. Active/Unconnected

6. Filter Transformation filters rows from any type of source

a. True b. False

Page 2: Day Three

7. If the filter condition entered in the Filter Transformation evaluates to NULL, then the condition returns

a. Trueb. Falsec. Depends on the datatype of the value returned by the conditiond. NULL

8. For the relational sources, filter condition in the Filter Transformation

a. Must use only standard SQL that returns either TRUE/FALSEb. Can be any condition that returns either TRUE/FALSEc. Can concatenate columns from the Source to evaluate the expression.d. Evaluates the condition if the Source is relational source only.

In Rank Transformation

9. Multiple ports can be selected to define a rank

a. Yes b. No

10. Variable Port can be designated as Rank Port

a. True b. False

11. Rank Port and GroupBy Port can be the same

a. True b. False

12. RANKINDEX port that the Designer automatically creates is

a. Input Portb. Output Portc. Input/Output Portd. Variable Port

13. What will be the out put when the following rows are passed into the Rank Transformation which is configured to select the top 5 salaried Employees,

In Sequence Generator Transformation

14. What are the transformation port types available in Sequence Generator Transformation.a. Input b. Input/Outputc. Output d. Input/Output/Variable

15. After every session run for a mapping containing Sequence Generator, the Informatica Server writes the Current Value to

a. Source Databaseb. Target Databasec. Repositoryd. To a Flat File in the Informatica Server $RootDir

16. NEXTVAL, CURRVAL ports of the Sequence Generator are by default

a. Input Portsb. Output Portsc. Input/Output Ports

Page 4: Day Three

d. Variable Ports

17. The default value for ‘Number Of Cached Values’ for a Reusable Sequence Generator Transformation is

a. 0b. 100c. 1,000d. 10,000

18. You can reset the values in Reusable Sequence Generator Transformation

a. Yesb. No

19. You can override the properties of the Sequence Generator Transformation at the Session Level

a. Yesb. No

20. To generate sequential values using Sequence Generator Transformation, you need to connect

a. NEXTVAL Port to the next Transformationb. CURRVAL Port to the next Transformationc. Both NEXTVAL and CURRVAL Ports to 2 different Ports in the next

Transformation
