Alibaba ACA-Developer Exam - Topic 9 Question 70 Discussion

As more businesses move online and collect more data about their users, databases are beginning to grow very large, affecting table query performance and business operations.

We can then remove the archived records from the original table to improve query performance. Which of these statements about this feature of DMS is NOT correct?
D) The user role of this operation must be 'administrator' or 'DBA'
A) The supported database types are RDS MySQL and PolarDB MySQL
B) Before you can use this feature of DMS, you must first enable Alibaba Cloud's Database Backup Service (DBS)
C) Backup data can be stored In OSS

I vaguely recall something about user roles needing to be 'administrator' or 'DBA' for certain operations, but I'm not completely confident about that.

I remember studying DMS features, but I'm not entirely sure if DBS is mandatory for archiving. It seems like it could be, but I need to double-check.

Okay, let me think this through step-by-step. The question is asking which statement about the DMS archiving feature is not correct. I'll need to analyze each option closely to determine the one that is incorrect.

I'm stumped on this one. Maybe I should just ask my cat for the answer. They're probably better at database management than I am.

The right answer is B, you don't need to enable DBS to use the archiving feature of DMS. That's just an additional step that isn't required.
