IBM InfoSphere DataStage v8.5 Sample Questions:

1. You are using the Change Capture stage in your job design to identify changes made to the input link (before image) to obtain the results in the output link. This job will be using a multi-node configuration file when executed.
What are two requirements on the input link data for the Change Capture stage? (Select two)

A) Sorted
B) Sequential mode
C) Key partitioned
D) Merged links

2. A customer requires that a single output file generated by a parallel job be created in sort order. Which two job designs would achieve this goal? (Choose two.)

A) Set the "Execution Mode" in the Advanced stage properties tab of the parallel Sort stage to execute sequentially.
B) Specify both partition and sort key columns on the input to the target SequentialFile stage.
C) Insert a sorted Funnel stage before the input to the output SequentialFile stage.
D) Write the result to a parallel dataset, then write a shell script to convert the dataset records to text format, in sorted order.
E) Use a parallel sort and partition the input to the SequentialFile stage using a Sort Merge collector.

3. What is the lowest CPU cost partitioning method?

A) Random
B) Round Robin
C) Hash
D) Entire

4. You are responsible for the projects Source Code Repository. When a developer notifies you that changes are ready to deploy you must first check them in. You will use the Information Server Source Code integration features to check in the changed assets. How will you identify the DataStage assets the developer modified in order to send them to the workspace?

A) From the Information Server Manager Select the project then right-click on Synchronize with source code control system.
B) From the workspace perspective select the project Right-click then Refresh from repository, specify a modification date and the developer's username in the Modified by fields.
C) From Information Server Manager use Search with advanced options, specify a date modified and the developer's user name in the Modified by fields.
D) Use Designer client Advanced Find, specify a modification date and the developer's username in the Modified by fields.

5. A job contains a Sort stage that sorts a large volume of data across a cluster of servers. Due to new requirements, the customer has requested that this sorting be done on a subset of servers identified in the configuration file to minimize impact on database nodes. The $APT_CONFIG_FILE shows no sort disk pool for any node. Which two steps will accomplish this? (Choose two.)

A) Assign a separate config file just for the Sort stage.
B) Define a non-default node pool with a subset of nodes in the parallel configuration file.
C) Have an appropriate node constraint within the Sort stage.
D) Create a sort scratch disk pool with a subset of nodes in the parallel configuration file.
E) Use the environment variable $APT_SCRATCH_SPACE_SORT_USAGE.
