Steve, a scientist who works in a governmental security agency, developed a technological solution to identify people based on walking patterns and implemented this approach to a physical control access.
A camera captures people walking and identifies the individuals using Steve’s approach.
After that, people must approximate their RFID badges. Both the identifications are required to open the door. In this case, we can say:

1. A. Although the approach has two phases, it actually implements just one authentication factor
2. B. The solution implements the two authentication factors: physical object and physical characteristic
3. C. The solution will have a high level of false positives
4. D. Biological motion cannot be used to identify people

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?

1. A. Attacker generates TCP SYN packets with random destination addresses towards a victim host
2. B. Attacker floods TCP SYN packets with random source addresses towards a victim host
3. C. Attacker generates TCP ACK packets with random source addresses towards a victim host
4. D. Attacker generates TCP RST packets with random source addresses towards a victim host
