What is the default protection level provided by Anti-DDoS Basic in mainland China?

The correct answer is 5 Gbps, which reflects the default level of protection provided by Anti-DDoS Basic in mainland China. This level of protection is designed to safeguard against Distributed Denial of Service (DDoS) attacks, which can overwhelm a network or server with excessive traffic and render it unusable.

Anti-DDoS Basic serves as a crucial first layer of defense for applications and websites that are hosted on Alibaba Cloud, helping to ensure continuity of service and prevent interruptions caused by malicious traffic. Having a baseline protection of 5 Gbps means that users can receive a considerable buffer against average attack traffic, allowing for more robust handling of legitimate traffic without being easily overwhelmed.

It's important to note that the option indicating 2 Gbps or lower amounts does not meet the expected security standards for most business or enterprise applications, particularly in environments where DDoS attacks are a significant threat. The options of 10 Gbps or higher also correspond to specialized or premium DDoS protection services rather than the standard offering provided by Anti-DDoS Basic.
