The HTTP protocol is based on TCP, so http Flood attacks can be defended against HTTP Flood attacks using the TCP Flood attack prevention method.

This statement is false. Although HTTP operates over TCP, the attack vectors for HTTP Flood and TCP Flood are fundamentally different. A TCP Flood (e.g., SYN Flood) targets the transport layer by exhausting a server's TCP connection table with half-open connections. In contrast, an HTTP Flood is an application-layer attack that uses seemingly legitimate HTTP GET or POST requests to consume application resources like CPU, memory, and database connections. Therefore, TCP Flood prevention mechanisms, such as SYN Cookies, which operate at the transport layer, are ineffective against application-layer HTTP Flood attacks that require content inspection and behavioral analysis for mitigation.

A. This option is not provided in a standard True/False format, but assuming 'A' represents 'True', it is incorrect because the defense mechanisms for Layer 4 and Layer 7 attacks are distinct.

This document clearly distinguishes between network-layer attacks (e.g., SYN flood) and application-layer attacks (e.g., HTTP flood), describing them as separate categories with different characteristics and mitigation methods.

2. Huawei. (2023). NE40E V800R023C00 Product Documentation, Security Configuration Guide - Attack Defense. Section: "Application-Layer Attack Defense Configuration". This section details specific commands and policies for mitigating HTTP Flood attacks, which are separate from the configurations for mitigating SYN Flood attacks.
