                          Question #1

                          Which two statements about using a Load write method in an Oracle Connector stage to tables that have indexes on them are true? (Choose two.)

                          • A. Set the Upsert mode property to "Index".
                          • B. The Load Write method uses "Rebuild" mode with no logging automatically.
                          • C. The Load Write method uses the Parallel Direct Path load method.
                          • D. Set the Index mode property to "Bypass".
                          • E. Set the environment variable APT_ORACLE_LOAD_OPTIONS to "OPTIONS (DIRECT=TRUE, PARALLEL=FALSE)".

                          Question #2

                          You are processing groups of rows in a Transformer. The first row in each group contains "1" in the Flag column and "0" in the remaining rows of the group. At the end of each group you want to sum and output the QTY column values. Which technique will enable you to retrieve the sum of the last group?

                          • A. Output the sum that you generated up to the previous row each time you process a row with a
                            "1" in the Flag column.
                          • B. Output a running total for each group for each row. Follow the Transformer stage by an
                            Aggregator stage. Take the MAX of the QTY column
                            for each group.
                          • C. Output the sum that you generated up to the previous row each time you process a row with a
                            "1" in the Flag column. Use the FirstRow()
                            function to determine when the group is done.
                          • D. Output the sum that you generated each time you process a row for which the LastRow()
                            function returns True.
                          Answer: B
                          Question #3

                          The derivation for a stage variable is: Upcase(input_column1) : ' ' : Upcase(input_column2). Suppose that input_column1 contains a NULL value. Assume the legacy NULL processing option is turned off. Which behavior is expected?

                          • A. The target stage variable is populated with spaces or zeros depending on the stage variable data type.
                          • B. The input row is either dropped or rejected depending on whether the Transformer has a reject link.
                          • C. The job aborts.
                          • D. NULL is written to the target stage variable.

                          Question #4

                          Which Oracle data type conversion is correct?

                          • A. Oracle data type NUMBER(15,0) converts to INT32 in Oracle Connector stage.
                          • B. Oracle data type RAW converts to RAW in Oracle Connector stage.
                          • C. Oracle data type NUMBER(6,0) converts to INT32 in Oracle Connector stage.
                          • D. Oracle data type NUMBER converts to DECIMAL(38,0) in Oracle Connector stage.
                          Answer: C
                          Question #5

                          A job design consists of an input Row Generator stage, a Sort stage, followed by a Transformer stage and an output Data Set stage. The job is run on an SMP machine with a configuration file defined with four nodes. The $APT_DISABLE_COMBINATION variable is set to True. How many player processes will this job generate?

                          • A. 16
                          • B. 13
