Alibaba Cloud Object Storage Service (OSS) does not solely rely on RAID 0+1 redundancy technology to achieve high data reliability. OSS uses a distributed system architecture to store data across multiple devices and servers. OSS also supports cross-region replication (CRR) to replicate data across different regions for disaster recovery. OSS is designed for 99.9999999999% (12 9’s) data durability and 99.995% service availability12. References:

The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet). This is true according to the Alibaba Cloud documentation on SLB1. Public SLBs are used to distribute traffic from the Internet to ECS instances, while private SLBs are used to distribute traffic within a VPC or a classic network2. References: 1: Server Load Balancer - Alibaba Cloud Documentation Center 2: Create a Server Load Balancer instance - Server Load Balancer - Alibaba Cloud Documentation Center

Alibaba Cloud OSS is designed for scalable and secure object storage, allowing users to upload and download files through multiple interfaces, including the web console and APIs, offering flexibility and ease of use for developers and administrators.

=================

OSS logging is a feature that allows you to record the access requests to your OSS buckets. You can enable and configure logging for a bucket in the OSS console or by using the OSS API. When logging is enabled for a bucket A, OSS automatically generates access log objects every hour and stores them in a specified bucket B. The log objects follow a predefined naming convention that includes the source bucket name, the date, the hour, and a unique string.

The documentation also states that buckets A and B can be separate buckets or the same bucket, but they must belong to the same user1. This means that you cannot store the access logs of one user’s bucket in another user’s bucket. Therefore, the correct answer is A.
