A TCP SYN flood attack uses the three-way handshake mechanism. The attacker at system A sends a SYN packet to the victim at system B. System B responds by sending a SYN/ACK packet to the attacker at system A. System A does not reply to system B, leaving victim B hung waiting for a response. Which of the following best describes the status of victim B?

The victim B is under attack.

Step-by-step explanation:

This scenerio is know as the TCP Half open scan. The attacker send to SYN packet to the victim just to know if a port is open.

A TCP Half Open Scan also referred to as SYN scanning determines if a port is open by performing the first half of a three-way handshake.

Attacker is trying to have TCP connection to a server through any port, this is done by sending a SYN (synchronization) packet, as if to initiate a three-way handshake, to every port on the server.

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
