1. What two features distinguish the Operations Console from the Director job log? (Choose two.)

A) Jobs can be started and stopped in Director, but not in the Operations Console.
B) The Operations Console can monitor jobs running on more than one DataStage engine.
C) The Operations Console can run on systems where the DataStage clients are not installed.
D) Workload management is supported within Director, but not in the Operations Console.
E) The Operations Console can monitor jobs running on only one DataStage engine.

2. 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_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".
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_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".
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".

3. Identify two restructure stages that allow you to create or organize vectors in the output link results? (Choose two.)

A) Split Subrecord
B) Column Import
C) Merge records
D) Split Vector
E) Make Subrecord

4. Your job sequence must be restartable. It runs Job1, Job2, and Job3 serially. It has been compiled with "Add checkpoints so sequence is restartable". Job1 must execute every run even after a failure. Which two properties must be selected to ensure that Job1 is run each time, even after a failure? (Choose two.)

A) Set the Job1 Activity stage to "Do not checkpoint run".
B) Set trigger on the Job1 Activity stage to "Unconditional".
C) In the Job1 Activity stage set the Execution action to "Run".
D) Use the Nested Condition Activity with a trigger leading to Job1; set the trigger expression type to "Unconditional".
E) In the Job1 Activity stage set the Execution action to "Reset if required, then run".

5. How does the Complex Flat File stage (CFF) support the use of OCCURS clauses within COBOL files?

A) Each element of the OCCURS clause is treated as a column of raw data.
B) The CFF stage cannot process COBOL files with OCCURS clauses.
C) Each element of the OCCURS clause is treated as a separate element in an array.
D) Each element of the OCCURS clause is treated as a subrecord.
