You are going to open a website. Which attackes can down your website?

DDoS (Distributed Denial of Service) attacks overwhelm a website with traffic from multiple sources, making it unavailable to legitimate users. 'Botting' is not a standard security term, 'unlimited pings' isn't a recognized attack type, and 'Echo attack' isn't a standard attack category. The question has grammatical issues ('attackes' typo) but the correct answer is clear.
