Correct Option: D

Which “Reject Mode” option in the sequential File Stage will write records to a reject link?

  1. Output

  2. Fail

  3. Drop

  4. Continue


Correct Option: A

AI Explanation

To answer this question, we need to understand the concept of "Reject Mode" in the sequential File Stage.

The "Reject Mode" option in the sequential File Stage determines how the stage handles records that do not meet the specified criteria or fail to be processed successfully.

Let's go through each option to understand why it is correct or incorrect:

Option A) Output - This option is correct because selecting the "Output" reject mode will write the rejected records to a reject link. This means that any records that do not meet the specified criteria or fail during processing will be sent to the reject link for further analysis or handling.

Option B) Fail - This option is incorrect because selecting the "Fail" reject mode will cause the job to fail when a record is rejected. It does not write the rejected records to a reject link.

Option C) Drop - This option is incorrect because selecting the "Drop" reject mode will simply discard the rejected records. It does not write them to a reject link for further analysis or handling.

Option D) Continue - This option is incorrect because selecting the "Continue" reject mode will allow the job to continue processing even when a record is rejected. It does not write the rejected records to a reject link.

The correct answer is Option A) Output. This option is correct because it will write the rejected records to a reject link for further analysis or handling.
