You are running a DataStage job using a 2-node configuration file. How can a fixed-width single sequential file be read in parallel? (Choose two.)

• A.Set the "Read From Multiple Nodes" optional property to a value greater than 1.
• B.Specify a node constraint for the SequentialFile stage.
• C.Set the "Number of Readers per Node" optional property to a value greater than 1.
• D.Use an external Source stage.
• E.Set the Execution Mode to the SequentialFile stage to "Parallel".

The result of a performance review for one of your job designs indicated this job needs to be split into two separate jobs. You also have been given the requirement to ensure you maintain parallelism (no re-partitioning) between these two new jobs.
Which single stage should you consider to accomplish maintaining parallelism and not introduce re-partitioning between these related jobs?

• A.Named Pipe stage
• B.Sequential File stage
• C.Copy stage
• D.Data Set stage

Records in a source file must be copied to multiple output streams for further processing. Which two conditions would require the use of a Transformer stage instead of a Copy stage? (Choose two.)

• A.Converting some input columns from integers to strings.
• B.Concatenating data from multiple input columns.
• C.Directing selected output records down one output link rather than another.
• D.Renaming one or more output columns.

You have a dataset hash-partitioned and sorted on CustID. You need to create a Sequential File sorted on CustID from this dataset. Which technique is the most appropriate?

• A.Use Copy stage.
• B.Use SortMerge collector for the Sequential File input link.
• C.Insert Sort stage before the final Sequential File stage and use Round Robin collector for the Sequential File stage input link.
• D.Insert Sort stage before the final Sequential File stage and use Ordered collector for the Sequential File stage input link.

When you run a parallel job, any error messages and warnings are written to the job log and can be viewed from the Director client. What two levels of message handlers are there? (Choose two.)

• A.stage level
• B.record level
• C.project level
• D.job level
