Q22. - (Topic 2)
What aretwo advantages of using Runtime Column Propagation (RCP)? (Choose two.)
A. RCP forces a developer to define all columns explicitly.
B. Only columns used in the data flow need to be defined.
C. Sequential files don't require schema files when using RCP.
D. Only columns that are defined as VarChar need RCP enabled.

Q24. - (Topic 2)
Indicate two possible job design topologies that Information Services Director (ISD) parallel jobs can conform to. (Choose two.)
A. A job with a single ISD Transformation stage.
B. Ajob with one ISD Input stage and no ISD Output stage.
C. A job with no ISD Input stage and with one ISD Output stage.
D. A job with greater then one ISD input stage and one ISD Output stage.
E. A job with one ISD Input stage and greater then one ISD Outputstage.
Q25. - (Topic 1)
You are assigned to correct a job from another developer. The job contains 20 stages sourcing data from two Data Sets and many sequential files. The annotation in the job indicates whowrote the job and when, not the objective of the job. All link and stage names use the default names. One of the output columns has an incorrect value which should have been obtained using a lookup. What could the original developer have done to make thistask easier for maintenance purposes?
A. Name all stage and links the same.
B. Name all stages and links based on what they do.
C. Indicate all stage names within the job annotation.
D. Name all stage and links with column names and ideas.

B. Missing Value
C. Sum of Squares
D. Mean Deviation
E. Coefficient of Variation
Q28. - (Topic 1)
In a Transformer, which two mappings can be handled by default type conversions. (Choose two.)
A. Integer input columnmapped to raw output column.
B. Date input column mapped to a string output column.
C. String input column mapped to a date output column.
D. String input column mapped to integer output column.
E. Integer input column mapped to string output column.
Q29. - (Topic 1)
Rows of data going into a Transformer stage are sorted and hash partitioned by the Input.Product column. Using stage variables, how can you determine when a new row is the first of a new group of Product rows?
A. Create a stage variable named sv_IsNewProduct and follow it by a second stage variable named sv_Product. Map the Input.Product column to sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product = sv_Product THEN "YES" ELSE "NO".
B. Create a stage variable named sv_IsNewProduct and follow it by a second stage variable named sv_Product. Map the Input.Product column to sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product <> sv_Product THEN "YES" ELSE "NO".
C. Create a stage variable named sv_Product and follow it by a second stage variable named sv_IsNewProduct. Map the Input.Product column to sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product = sv_Product THEN "YES" ELSE "NO".
D. Createa stage variable named sv_Product and follow it by a second stage variable namedsv_IsNewProduct. Map the Input.Product column to sv_Product. The derivation for sv_IsNewProduct is: IF Input.Product <> sv_Product THEN "YES" ELSE "NO".
Q30. - (Topic 2)
Which DB2 to InfoSphere DataStage data type conversion is correct when reading data with the DB2 Connector stage?
A. XML to SQL_WVARCHAR
B. BIGINT to SQL_BIGINT (INT32)
C. VARCHAR, 32768 to SQL_VARCHAR
D. CHAR FOR BIT DATA to SQL_VARBINARY
