25 Questions from the CompTIA Network+ Exam
1. What is the purpose of a network switch?
A network switch is a device that connects multiple devices together on a network. It forwards data packets between devices based on their MAC addresses.
2. What is the difference between a hub and a switch?
A hub is a simple device that simply repeats all data packets it receives to all other devices connected to it. A switch, on the other hand, is a more intelligent device that forwards data packets only to the devices that are addressed in the packet.
3. What is a subnet mask?
A subnet mask is a 32-bit number that is used to divide a network into smaller subnets. The subnet mask is used by the network switch to determine which devices are on the same subnet as the sending device.
4. What is a default gateway?
A default gateway is a router that is used to send data packets to destinations that are not on the local subnet.
5. What is a DNS server?
A DNS server is a server that translates human-readable domain names into IP addresses.
6. What is a DHCP server?
A DHCP server is a server that automatically assigns IP addresses to devices on a network.
7. What is a VLAN?
A VLAN is a virtual network that is created on a physical network. VLANs can be used to segment traffic on a network, improve security, and improve performance.
8. What is a firewall?
A firewall is a device that monitors and filters network traffic. Firewalls can be used to protect networks from unauthorized access and attacks.
9. What is a VPN?
A VPN is a virtual private network that creates a secure connection between two or more devices over a public network. VPNs can be used to protect data privacy and security.
10. What is a port scanner?
A port scanner is a tool that can be used to scan a network for open ports. Open ports can be used by attackers to exploit vulnerabilities on a system.
11. What is a vulnerability scanner?
A vulnerability scanner is a tool that can be used to scan a system for known vulnerabilities. Vulnerabilities can be exploited by attackers to gain unauthorized access to a system.
12. What is a patch management system?
A patch management system is a system that is used to deploy security patches to systems on a network. Security patches can be used to fix vulnerabilities on systems.
13. What is a change management system?
A change management system is a system that is used to manage changes to a system. Change management systems can help to ensure that changes are made in a controlled and secure manner.
14. What is a risk assessment?
A risk assessment is a process of identifying and assessing the risks to a system. Risk assessments can be used to prioritize security controls and to make informed decisions about security investments.
15. What is a security policy?
A security policy is a document that defines the security requirements for a system. Security policies can be used to guide security decisions and to help ensure that security controls are implemented effectively.
16. What is a security incident?
A security incident is an event that may have a negative impact on the security of a system. Security incidents can include unauthorized access, data breaches, and denial-of-service attacks.
17. What is a security incident response plan?
A security incident response plan is a document that defines the steps that will be taken to respond to a security incident. Security incident response plans can help to minimize the impact of a security incident.
18. What is a security awareness training program?
A security awareness training program is a program that is used to educate employees about security risks. Security awareness training programs can help to reduce the risk of human error, which is a leading cause of security breaches.
19. What is a penetration test?
A penetration test is an authorized attempt to exploit vulnerabilities on a system. Penetration tests can be used to identify and fix vulnerabilities on systems.
20. What is a security audit?
A security audit is an independent assessment of the security of a system. Security audits can be used to identify security weaknesses and to make recommendations for improvement.
21. What is a security architecture?
A security architecture is a high-level plan for the security
22. What is a security operations center (SOC)?
A security operations center (SOC) is a team of security professionals who are responsible for monitoring, detecting, and responding to security incidents. SOCs typically use a variety of tools and technologies to monitor networks and systems for suspicious activity.
23. What is a threat intelligence platform?
A threat intelligence platform is a tool that is used to collect, store, and analyze threat intelligence data. Threat intelligence data can be used to identify and mitigate threats before they can cause harm.
24. What is a security information and event management (SIEM) system?
A security information and event management (SIEM) system is a tool that is used to collect, store, and analyze security logs and events. SIEM systems can be used to identify security threats, investigate security incidents, and improve security posture.
25. What is a security incident response team (SIRT)?
A security incident response team (SIRT) is a team of security professionals who are responsible for responding to security incidents. SIRTs typically have a set of procedures and processes in place to respond to incidents in a timely and effective manner.
