IBM InfoSphere DataStage v9.1 Sample Questions:
1. 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_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".
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_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".
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".
2. What is used to configure the DataStage QualityStage Operations Console?
A) The DSODBCConfig.cfg file
B) The DSAppWatcher.sh script
C) Information Server Web Console
D) DataStage Administrator
3. The parallel framework was extended for real-time applications. Identify two of these aspects. (Choose two.)
A) Real-time stage types that keep jobs always up and running.
B) XML stage.
C) Real-time stage types that re-run jobs.
D) End-of-wave.
E) Support for transactions within source database connector stages.
4. Which derivations are executed first in the Transformer stage?
A) Loop variable derivations
B) Input column derivations
C) Output column derivations
D) Stage variable derivations
5. Which statement is true about Information Server logging?
A) Severity levels specify the threshold for saving events in the metadata repository.
B) Multiple configurations can be active at the same time.
C) You must log into the Information Server Web Console as a DataStage administrator in order to configure logging.
D) You can activate or de-activate the logging configuration in DataStage Administrator.
