What is a Distributed Reflective Denial-of-Service (DRDoS) attack?

What is the Xmas scan and what potential impact does it have?
*

1 point

It involves sending ping packets to the victim that exceed the standard size limit, and can cause the victim to become overwhelmed and crash.

It involves sending malformed packets to a computer's open ports, and can exhaust the available bandwidth.

It involves sending UDP packets to port 7 or port 19, and can cause freezing or crashing of the victim.

It involves sending TCP packets with URG, PSH, and FIN flags activated to specified ports, and can adversely impact the targeted system's performance or escalate to a DoS attack.

What is the main difference between a DoS attack and a DDoS attack?
*

1 point

There is no difference between DoS and DDoS attacks.

DoS attacks involve multiple intermediary systems while DDoS attacks do not.

DDoS attacks involve multiple intermediary systems while DoS attacks do not.

*

1 point
