C) String input column mapped to integer output column.
D) Integer input column mapped to string output column.
E) Integer input column mapped to raw output column.
2. You have been asked to delete a shared container from the project by your customer. Before you do this you want to make sure it will not impact other objects in the project. How will you ensure that deleting the shared container will not cause a failure when jobs are recompiled?

D) Advanced find, set Dependencies Of field equal to the container name, and Check the Option to Include nested results for Dependency searches.
3. You are required to use a Make Vector stage in your job. What three requirements must be met in order to use this stage? (Choose three.)
A) Columns must be in consecutive order.
B) Input columns that do not have a name of form <column_name>0 to <column_name>n, where <column_name> is the column name and 0 and n are the first and last of its consecutive numbers will not be included in the vector and will be dropped.
C) Input columns must all be of the same data type.
D) Input columns must form a numeric sequence.

5. Input rows to a Transformer contain a product name field and a field with a list of colors the product can be ordered with. The colors are separated by the pipe character (|). Here is an example of an input row: "Shirt"| ....| "Red, Blue, Black"|... For each input row, you want to output multiple output rows, one for each color in the list. For the above example input row, three rows are to be output, one per color: "Shirt" ... "Red", "Shirt" ... "Blue", "Shirt" ... "Black".
Which three operations will you need to accomplish this? (Choose three.)
A) Specify the following loop condition: @ITERATION <= n, where n is a stage variable initialized with number of loop iterations.
B) Use the Count() function over the ColorList field to determine the number of loop iterations.
C) Use the @ITERATION variable to determine which color in the ColorList field to extract using the Field function.
D) Use the LastRowInGroup() function to determine when the last color in the color list has been processed.
E) Use the SaveInputRecord() to save the input row for processing in the loop. Use the GetInputRecord() to extract the row for each iteration of the loop.
