質問 2：
What are the advantages of Huawei cloud database RDS compared with self-purchased servers to build databases? (Multiple choice)
A. Maintenance cost: cloud database RDS basically does not require operation and maintenance, and self-built databases require more labor costs
B. Deployment expansion: ApsaraDB for RDS elastic expansion, opened on demand, self-built database needs to purchase hardware that matches the original equipment, the overall cycle is longer
C. Resource utilization, cloud database RDS is settled on an annual basis. Compared with monthly settlement, the cost is higher. Self-built databases need to consider the peak value. During peak business periods, the resource utilization rate is low
D. Data backup: ApsaraDB for RDS supports automatic and manual backups, and also supports custom backup storage periods. Self-built databases need to purchase backup equipment, specify settings and post-maintenance by yourself
正解：A,B,D
