Alibaba Cloud Certified Associate – Cloud Computing — Question 8

Alibaba Cloud provides anti-DDoS products of different levels. If the service availability needs to be kept at 99.9% or higher under DDoS attacks, which of the following is the MOST suitable product?

Answer options

Correct answer: D

Explanation

The Anti-DDoS Service Pro is designed to handle severe DDoS attacks and ensure high service availability, making it the most suitable choice for maintaining 99.9% uptime. The other options, like Anti-DDoS Service Basic, do not provide the same level of protection against large-scale attacks, while Managed Security Service and Situation Awareness are more focused on overall security management rather than specifically mitigating DDoS threats.
