Which of the following statements is NOT correct, when comparing RDS with a self-built database?

 The statement A is not correct, because self-built databases do not support quick deployment and elastic scaling. On the contrary, self-built databases require hardware procurement, data center hosting, and machine deployment, which can be time consuming and costly. Moreover, self-built databases have low resource utilization, as they have to accommodate peak traffic requirements, while RDS can scale elastically according to the actual demand. References: = ApsaraDB for RDS vs. Self-built Databases - Alibaba Cloud
