Then you should specify all workload and tuning options as needed.
Thereafter you need select the Generate only online recommendations check box in the Advanced Tuning Options dialog box.

Explanation:
One of the requirements is to guarantee maximum performance on Certkiller -DB01 during analysis, therefore storing the workload file on Certkiller -DB01 when running DTA is out of the question. You only want suggestions from the DTA that can be implemented while the database is online; therefore you should choose the Generate only online recommendations.
