Domain Name System (DNS)
#5

Which layer of the OSI model do firewalls primarily operate on?

Physical Layer
Data Link Layer
Network Layer
Transport Layer
#6

What is a DMZ in the context of network security?

Demilitarized Zone - an area where military-grade encryption is applied
Database Management Zone - a secure area for storing sensitive data
Delegated Management Zone - an area for user access management
Demilitarized Zone - an isolated network segment between the internal network and an external network, typically the internet
#7

Which type of firewall examines each packet in isolation without considering the context of other packets?

Stateful Firewall
Packet Filtering Firewall
Proxy Firewall
Application Layer Firewall
#8

What is a VPN (Virtual Private Network) primarily used for?

To increase internet speed
To create a secure connection over a public network, such as the internet
To filter spam emails
To encrypt data on a local network
#9

What does NAT (Network Address Translation) do in the context of firewall and network security?

Encrypts data packets for secure transmission
Filters out malicious packets
Translates private IP addresses to public IP addresses and vice versa
Provides user authentication for network access
#10

What is the role of a proxy server in network security?

To provide a secure connection for remote users
To intercept and forward network traffic on behalf of clients
To encrypt all incoming and outgoing packets
To manage user access control
#11

What is the purpose of a DDoS mitigation system?

To encrypt data transmission
To monitor and analyze network traffic for suspicious activities
To filter spam emails
To detect and mitigate Distributed Denial of Service (DDoS) attacks
#12

What is a 'Stateful Inspection' in firewall terminology?

Examining packets individually without considering their relationship to other packets
Inspecting the state of active connections and determining whether incoming packets are allowed based on the connection state
Applying encryption to all incoming and outgoing packets
Analyzing the content of each packet to detect malicious code
#13

What is the purpose of a honeypot in network security?

To collect and analyze data from malicious packets
To detect and deflect denial-of-service attacks
To simulate vulnerable systems to attract attackers and gather information about their techniques and motives
To provide secure storage for sensitive data
#14

Which of the following is a characteristic of a zero-day exploit?

It is a well-known and widely used vulnerability
It targets vulnerabilities that have been previously patched
It is only effective on weekends
It exploits vulnerabilities that are unknown to software vendors and have no available patch
#15

What is the difference between symmetric and asymmetric encryption?

Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses different keys
Symmetric encryption is faster than asymmetric encryption
Asymmetric encryption is more secure than symmetric encryption
Symmetric encryption is used for securing email communication
#16

What is a man-in-the-middle (MITM) attack?

An attack that targets vulnerabilities in web servers
An attack where an attacker intercepts and alters communication between two parties without their knowledge
A type of social engineering attack
An attack that floods a network with excessive traffic, causing denial of service
#17

What is a rainbow table in the context of password security?

A table used to crack passwords by brute force
A table used to store hashed passwords for secure storage
A precomputed table used to reverse cryptographic hash functions to plaintext passwords
A table used to organize user credentials for authentication
#18

What is the purpose of network segmentation in network security?

To increase network performance
To isolate sensitive or critical assets from other parts of the network, reducing the impact of a security breach
To filter spam emails
To manage user access control
