7.3.2 Recon with Scanning

What is the primary purpose of a Network Scanner like nmap?

• To repair network devices

• To enumerate and fingerprint devices in a network to identify vulnerabilities

• To increase network speed

• To monitor data usage on a network

What does "Enumeration" in the context of Network Scanning involve?

• Deleting data from the network

• Identifying the computers in a network and details such as services, hostnames, file shares, usernames, etc.

• Encrypting network communications

• Installing software updates across network devices

What is "Fingerprinting" in the context of Network Scanning?

• The process of removing fingerprints from network devices for security

• The process of adding security patches to the operating system

• Identifying the specific OS or application running on a system

• Monitoring the internet usage by the network users

Which tool is mentioned as the most popular network scanning tool?

• Ping

• Zenmap

• Nmap

• Netstat

What is the GUI version of Nmap called?

• NetGUI

• NmapGUI

• Zenmap

• MapNet

What is the first step in the TCP 3-way handshake process used by Nmap to establish a connection?

• The server sends a SYN-ACK packet

• The client sends an ACK packet

• The client sends a SYN packet

• The server sends an ACK packet

What does the server send in response to the initial packet in the TCP 3-way handshake?

• SYN

• ACK

• SYN-ACK

• Data packet

What is the final step from the client to complete the TCP 3-way handshake after receiving a SYN-ACK?

• Send another SYN packet

• Send a SYN-ACK packet

• Send an ACK packet and start sending data

• Terminate the connection

What is the primary function of nmap?

• To establish secure email communications

• To send different types of packets and observe the responses

• To create a visual map of network topologies

• To encrypt data packets

What is the purpose of a Host Discovery Scan in nmap?

• To determine the software and version used by servers

• To find which hosts are live in a network

• To find which ports are open on a host

• To determine what Operating System is being used by the host
