What is a difference between a DoS attack and DDos attack?

The correct answer is C. A DoS attack is where a computer is used to flood a server with TCP and UDP packets whereas. A Denial of Service (DoS) attack originates from a single source, flooding a target with traffic, while a Distributed Denial of Service (DDoS) attack involves multiple, geographically dispersed compromised systems to overwhelm a target.

Why each option

A Denial of Service (DoS) attack originates from a single source, flooding a target with traffic, while a Distributed Denial of Service (DDoS) attack involves multiple, geographically dispersed compromised systems to overwhelm a target.

AA DoS attack is where a computer is used to flood a server with UDP packets whereas a DDoS

DoS attacks are not limited to UDP packets; they can utilize various protocols, and the primary distinction is the number of attacking sources.

BA DoS attack is where a computer is used to flood a server with TCP and UDP packets whereas

The primary distinction between DoS and DDoS is the number of attacking sources, not just the types of packets used; both can use TCP and UDP.

CA DoS attack is where a computer is used to flood a server with TCP and UDP packets whereasCorrect

A DoS attack typically originates from a single source machine that floods the target with traffic, often using protocols like TCP and UDP, whereas a DDoS attack leverages multiple, distributed compromised machines (a botnet) to launch a coordinated attack, making it harder to mitigate.

DA DoS attack is where a computer is used to flood a server with TCP packets whereas a DDoS

DoS attacks are not limited to TCP packets; they can utilize various protocols, and the primary distinction is the number of attacking sources.
