IBM Certified Solution Developer - IBM InfoSphere DataStage Sample Questions:
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 who wrote 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 this task easier for maintenance purposes?
A) Name all stage and links with column names and ideas.
B) Indicate all stage names within the job annotation.
C) Name all stage and links the same.
D) Name all stages and links based on what they do.
2. What is used to configure the DataStage QualityStage Operations Console?
A) DataStage Administrator
B) Information Server Web Console
C) The DSAppWatcher.sh script
D) The DSODBCConfig.cfg file
3. Which partitioning method requires a key?
A) Round Robin
B) Same
C) Modulus
D) Sort Merge
4. Which statement describes what happens when Runtime Column Propagation is disabled for a parallel job?
A) An input column value flows into a target column only if it matches it by name.
B) An input column value flows into a target column only if it is explicitly mapped to it.
C) An input column value flows into a target column based on its position in the input row. For example, first column in the input row goes into the first target column.
D) You must set APT_AUTO_MAP project environment to true to allow output link mapping to occur.
5. Your job is using the Sequential File stage as a source. Identify two stage property configurations that will allow you to accomplish parallel reads? (Choose two.)
A) Read Method property set to 'Specific File(s)' with only one file specified and the 'Readers Per Node' property value set to greater than 1.
B) Read Method property set to 'Specific File(s)' with more than one file specified and each file specified has the same format/column properties.
C) Read Method property set to 'File Pattern' and the environment variable $APT_IMPORT_PATTERN_USES_FILESET is set to 'FALSE'.
D) Read Method property set to 'File Pattern' and the 'Readers per Node' property value set to greater than 1.
E) Read Method property is set to 'Parallel' with the Key property set to a Input column that has the file names.
