What are common types of Layer 7 DDoS attacks?

Common Layer 7 DDoS attacks include HTTP Flood, where attackers send a high volume of seemingly legitimate HTTP requests to overload web servers; Slowloris, which opens multiple connections to a web server and keeps them open by sending partial HTTP requests, eventually exhausting the server's connection pool; and DNS Flood, which targets DNS servers by overwhelming them with resolution requests, making it difficult for legitimate users to access services.
