IBM Assessment: InfoSphere DataStage v8.5 Sample Questions:

Question 1

You would like to run a particular processing job within a job sequence for each weekday of the week. How could you do this? (Select two)

A. Start Loop and End Loop activity stages on the job sequencer canvas where you loop through the days and pass a value for each day into the job via parameter.
B. Set the frequency property in the job scheduler to weekdays only.
C. Have a parameter set that contains the days of the week you would like to process and routine to parse the days of the week contained in the "day" parameter.
D. Call a routine in the job sequencer that starts the processing job for each day you would like to process.

Question 2

You need to find the differences between the jobs in the Test project and theit older version in the Production project. You discover that the Production project is on another domain. What feature would find the differences in a job that is in a project on a different domain?

A. Cross Project Compare
B. Cross Domain Compare
C. DataStage Version Control
D. Export from the other domain and import into a project in the same domain as the one you are working in.

Question 3

A client has multiple servers connected with a high bandwidth switch and has installed DataStage on one of them. There are five files (with the same record layout) that must be retrieved from three other servers using FTP. Which approach will retrieve and process all five files in the minimal amount of time?

A. In a single job, use three separate FTP Enterprise stages (one for each machine) with output links to a single Sort Funnel stage. Next, process the records without landing to disk.
B. Use a single FTP Enterprise stage and specify five URI properties (one for each file). Next, process the records without landing to disk.
C. In a single job, use five separate FTP Enterprise stages with output links to a single Sort Funnel stage. Next, process the records without landing to disk.
D. Create a sequence containing five separate DataStage jobs which each retrieve a single file and append it to a common Data Set. Next, process the resulting Data Set in an sixth DataStage job.

Question 4

Which two features of Data Sets make them suitable for job restart points? (Choose two.)

A. They are compressed to minimize storage space.
B. They are persistent.
C. They use the same data types as the parallel framework.
D. They are indexed to improve access.

Question 5

An important top level Job Sequence has been modified. It controls a process flow consisting of sub Job Sequences, Routines and Parallel Jobs. You must set up a new project to test the top level Job Sequence. You are not allowed to move any repository objects that are not impacted by the top level Job Sequence.
What two options would identify only the repository objects impacted by the change made to the top level Job Sequence? (Select two)

A. Repository Advanced Find Where Used
B. On Export check Include dependencies of
C. Click Impact Analysis Icon on Designer Client Toolbar.
