Question 1 of 40

Assume you have before and after data sets and want to identify and process all of the changes between the two data sets. Assuming data is properly partitioned and sorted, which of the following should be used?

    Correct Answer: D

    To identify and process all of the changes between two data sets, both 'Change Capture' and 'Change Apply' should be used. 'Change Capture' is used to identify the changes between the initial and modified data sets, while 'Change Apply' is responsible for processing those identified changes. Using these two together ensures that all changes are not only identified but also suitably processed.

Question 2 of 40

In the Masking Policy Editor in the Data Masking stage of your job, you have specified for a column containing credit card numbers the Random Replacement masking policy. For the Copy option you have specified "(1,2)(3,4)".

What changes will be made to a credit card number, such as 6327664369, to mask it?

    Correct Answer: A

    When specifying the Copy option as '(1,2)(3,4)' in the Random Replacement masking policy, the numbers within the parentheses indicate groups of digits to be changed. Therefore, digits 1 through 2 and digits 3 through 4 of the credit card number will be randomly changed. The rest of the digits will remain unchanged.

Question 3 of 40

Which stages will require a schema file when runtime column propagation (RCP) is enabled? (Choose two.)

    Correct Answer: B, E

    When runtime column propagation (RCP) is enabled, a schema file is required in certain stages to define the metadata for columns. The Column Import stage requires a schema file because it uses the schema to import the necessary metadata about the columns being processed. The Make Subrecord stage also requires a schema file because it deals with creating subrecord structures based on the defined schema. Therefore, the stages that require a schema file when RCP is enabled are Column Import and Make Subrecord.

Question 4 of 40

Which of the following actions are available when editing a message handler?

    Correct Answer: C

    When editing a message handler, one of the actions available is to promote an informational message to a warning. This action changes the severity level of a message, making it more prominent in the logging or monitoring systems.

Question 5 of 40

The Lookup stage is one of three stages that join records based on the values of key columns. What are the other stages? (Choose two.)

    Correct Answer: A, B

    The Lookup stage is indeed used to join records based on key column values. The other stages that perform similar joining operations are the Join stage and the Merge stage. The Join stage combines records from two input links by performing a relational join. The Merge stage combines records from multiple input links based on key columns and produces a merged output. Therefore, the correct options are Join and Merge.
