Exam 312-50v12 topic 1 question 209 discussion

RST hijacking involves injecting an authentic-looking reset (RST) packet by using a spoofed source IP address and predicting the acknowledgment number.

Fairly certain this is A as it states in the questions "guessed acknowledgment number" so if the attacker guessed the acknowledgment number and is trying to inject an RST packet to reset the connection and was successful then the outcome would still be the same. I really feel like since the posted in the question that it was guessed it should eliminate any of other options but they put in the RST hijacking to try and throw people off.

RST hijacking involves injecting an authentic-looking reset (RST) packet using spoofed source address and predicting the acknowledgment number.

RST Hijacking RST hijacking involves injecting an authentic-looking reset (RST) packet using spoofed source address and predicting the acknowledgment number. The hacker can reset the victim's connection if it uses an accurate acknowledgement number. The victim believes that the source actually sent the reset packet and resets the connection. RST Hijacking can be carried out using a packet crafting tool such as Colasoft's Packet Builder and TCP/IP analysis tool such as tcpdump.

Team can you confirm if this is accurate
