Network & Perimeter Security

What is the primary purpose of network security?

• Enhancing network speed

• Preventing unauthorized access and cyber threats

• Increasing data storage capacity

• Optimizing server performance

Which technology acts as the first line of defense in protecting an organization's network from external threats?

• Intrusion Detection and Prevention Systems (IDPS)

• Firewalls

• Virtual Private Networks (VPNs)

• Access Control Lists (ACLs)

Which of the following best describes the main function of a WAN?

• Connecting devices within a limited geographic area

• Sharing resources among devices in a specific location

• Facilitating communication between geographically dispersed locations

• Providing high-speed internet access

Which device is commonly used in LANs to forward data packets to the appropriate destination device within the same network segment?

• Router

• Switch

• Firewall

• Hub

In a WAN, what do routers use to determine the optimal path for data packets to reach their intended destination across different networks?

• IP addresses

• MAC addresses

• Port numbers

• Usernames

What is the main benefit of using switching technology in a LAN?

• Enhanced network performance and reduced congestion

• Increased data transfer rates
