#1
What is the primary goal of network scanning?
To identify and locate vulnerabilities in a network
To encrypt communication between devices
To monitor network traffic
To install security patches
#2
What is the purpose of ARP (Address Resolution Protocol) in networking?
To resolve domain names to IP addresses
To resolve IP addresses to MAC addresses
To encrypt network communication
To route data between networks
#3
What is the concept of 'packet sniffing' in network security?
Detecting malicious packets on the network
Capturing and analyzing network traffic
Encrypting packets for secure transmission
Blocking unwanted packets
#4
Which network scanning technique aims to identify live hosts within a network?
Port Scanning
Ping Sweeps
Packet Sniffing
Vulnerability Scanning
#5
In the context of network scanning, what is a 'false positive'?
An incorrect identification of a vulnerability that doesn't exist
A security feature that is incorrectly disabled
A successful penetration test
A type of DDoS attack
#6
Which of the following is a passive network scanning technique?
Ping Sweeps
Port Scanning
Packet Sniffing
Traceroute
#7
What is the purpose of a firewall in network security?
To scan for viruses on the network
To block unauthorized access and control incoming/outgoing network traffic
To manage network bandwidth
To authenticate users
#8
Which protocol is commonly used for network mapping and discovery?
#9
What is the purpose of a honeypot in network security?
To attract and detect malicious activity
To enhance network speed
To encrypt communication
To manage IP addresses
#10
What is the difference between a vulnerability scan and a penetration test?
They are synonymous terms
A vulnerability scan identifies weaknesses, while a penetration test exploits them
A penetration test identifies weaknesses, while a vulnerability scan exploits them
They are both passive security measures
#11
What is the purpose of traceroute in network analysis?
To identify active devices on a network

Metasploit
#13
What is banner grabbing in the context of network security?
Capturing advertising banners on websites
Obtaining information about a service/version running on a remote system
Monitoring network bandwidth usage
Displaying messages on networked devices
#14
In the context of network scanning, what does the term 'OS fingerprinting' refer to?
Identifying the operating system of a target system
Collecting fingerprints for authentication
Capturing screenshots of the operating system
Scanning open ports on a system
#15
Which of the following is a vulnerability scanning tool?
Wireshark
Nessus
Netcat
Tcpdump
#16
Which type of scan sends a reset packet to the target system to determine if a port is open?
SYN Scan
ACK Scan
FIN Scan
RST Scan
#17
What is the purpose of the Common Vulnerabilities and Exposures (CVE) system?
To identify network devices
To standardize the names of vulnerabilities
