문제 #1
How must the input data set be organized for input into the Join stage? (Choose two.)

A. Entire partitioned
B. Key partitioned
C. Hash partitioned
D. Unsorted
E. Sorted by Join key

문제 #2
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_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".
B. 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".
C. 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".
D. 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".

문제 #3
The parallel framework was extended for real-time applications. Identify two of these aspects. (Choose two.)

A. XML stage.
B. Support for transactions within source database connector stages.
C. Real-time stage types that re-run jobs.
D. Real-time stage types that keep jobs always up and running.
E. End-of-wave.

문제 #4
Two new columns have been deleted from a sequential file that a number of DataStage jobs write to. You have imported a table definition for the changed file. How can you determine what jobs might be affected by this change?

A. Select the new table definition, right-click, click on the Compare against command, then select original table definition.
B. Select the original table definition, right-click, then click on the Find dependencies command.
C. Select the new table definition, right-click, then click on the Where used command.
D. Select the original table definition, right-click, then click on the Where used command.

문제 #5
Which job design technique can be used to give unique names to sequential output files that are used in multi-instance jobs?

A. Use DSJoblnvocationID to generate a unique filename.
B. Use a Transformer stage variable to generate the name.
C. Use parameters to identify file names.
D. Generate unique file names by using a macro.
