A) Two instances.
B) One instance.
C) Three instances.
D) Four instances.

2. What two project environment variables can be considered in your parallel jobs to support your optimization strategy of partitioning and sorting? (Choose two.)

A) $APT_OPT_SORT_INSERTION
B) $APT_PARTITION_FLUSH_COUNT
C) $APT_RESTRICT_SORT_USAGE
D) $APT_TSORT_STRESS_BLOCKSIZE
E) $APT_NO_PART_INSERTION

3. Which two file stages allow you to configure rejecting data to a reject link? (Choose two.)

A) Lookup File Set Stage
B) Big Data File Stage
C) Complex Flat File Stage
D) Data Set Stage
E) Compare Stage

4. 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_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".
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_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".

5. 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) Use the Nested Condition Activity with a trigger leading to Job1; set the trigger expression type to "Unconditional".
C) In the Job1 Activity stage set the Execution action to "Run".
D) Set trigger on the Job1 Activity stage to "Unconditional".
E) In the Job1 Activity stage set the Execution action to "Reset if required, then run".
