I'm pretty sure option D is the correct answer. The repetition option allows you to repeat the complete migration, not just a subset of tables like the benchmarking one.
Okay, let me try to break this down. The benchmaking option allows you to migrate a specified set of tables, not repeat the entire uptime migration. And the repetition option lets you rerun the full migration without a shadow system. Does that sound right?
Haha, I bet the exam writers were having a field day coming up with this one. 'Benchmaking' - is that like making a benchmark out of beeswax or something?
I think the key difference is that benchmarking allows you to migrate a specified set of tables, whereas repetition lets you run the full migration again without a shadow system. But I'm not totally confident in that.
This question seems a bit confusing to me. What exactly is the difference between benchmarking and repetition in the Database Migration Option of SUM? I'm not sure I understand the nuances here.
