The connect scan is similar to the SYN scan, but completes the three-way handshake unlike the SYN scan.

Answer: C
 The XMAS scan is a type of port scan that sends packets with the FIN, URG, and PUSH flags set. It is used to identify listening ports on a target system.

Answer: F
 The ACK scan is used to determine whether a port is filtered, unfiltered, or open. It sends a packet with the ACK flag set to a certain port and waits for a response. If it receives a RST packet, the port is unfiltered; if it receives no response, the port is filtered; and if it receives an ACK packet, the port is open.

Answer: G
 When a port is filtered, it means that the packets sent to that port are being blocked by a firewall or other security device. A port scan may be able to determine that the port is filtered but will not be able to determine whether the port is open or closed.

Answer: H
 An open port is a port that is listening for incoming connections. A port scan may be able to detect an open port by sending packets to that port and waiting for a response.
