A company stores data in OSS buckets. According to the company’s security policy, static data must be encrypted at rest.
Which of the following methods can meet this requirement?
An e-commerce platform, implementing a high availability architecture, uses an Alibaba Cloud Server Load Balancer (SLB) instance to connect user terminals to its applications.
