Which of the following statements about Denial-of-Service (DoS) attack are true? Each correct answer represents a complete solution. Choose three.

The correct answer is A. It disrupts services to a specific computer. C. It saturates network resources. D. It disrupts connections between two computers, preventing communications between. A DoS attack disrupts availability by overwhelming a target system or network, severing connections and denying service - it does not modify protocol configurations.

Why each option

A DoS attack disrupts availability by overwhelming a target system or network, severing connections and denying service - it does not modify protocol configurations.

AIt disrupts services to a specific computer.Correct

DoS attacks are designed to disrupt or deny services on a specific targeted computer by exhausting its resources such as CPU, memory, or bandwidth.

BIt changes the configuration of the TCP/IP protocol.

DoS attacks do not change TCP/IP protocol configuration on victim machines - they exploit existing protocol behavior rather than modifying it.

CIt saturates network resources.Correct

A core goal of DoS attacks is to saturate network resources such as bandwidth or connection tables, preventing legitimate traffic from reaching the target.

DIt disrupts connections between two computers, preventing communications betweenCorrect

DoS attacks can disrupt established connections between two computers - for example, TCP RST injection or resource exhaustion can tear down active sessions and prevent further communication.
