• Question 204:

  When a normal TCP connection starts, a destination host receives a SYN (synchronize/start) packet from a source host and sends back a SYN/ACK (synchronize acknowledge). The destination host must then hear an ACK (acknowledge) of the SYN/ACK before the connection is established. This is referred to as the "TCP three-way handshake." While waiting for the ACK to the SYN ACK, a connection queue of finite size on the destination host keeps track of connections waiting to be completed. This queue typically empties quickly since the ACK is expected to arrive a few milliseconds after the SYN ACK.

  How would an attacker exploit this design by launching TCP SYN attack?

  A. Attacker generates TCP SYN packets with random destination addresses towards a victim host

  B. Attacker floods TCP SYN packets with random source addresses towards a victim host

  C. Attacker generates TCP ACK packets with random source addresses towards a victim host

  D. Attacker generates TCP RST packets with random source addresses towards a victim host

  Correct Answer: B

  How can Fred accomplish this?

  B. He can send an IP packet with the SYN bit and the source address of his computer.

  C. Fred can send an IP packet with the ACK bit set to zero and the source address of the switch.

  D. Fred can send an IP packet to the switch with the ACK bit and the source address of his machine.

  You want to retrieve the Cisco configuration from the router. How would you proceed?

  A. Use the Cisco's TFTP default password to connect and download the configuration file

  B. Run a network sniffer and capture the returned traffic with the configuration file from the router

  C. Run Generic Routing Encapsulation (GRE) tunneling protocol from your computer to the router masking your IP address
