What are common types of firewall deployment architectures?

The correct answer highlights key deployment architectures commonly used within firewall systems. When discussing firewall deployment, the distinction between primary, high availability, and virtual firewalls is significant.

A primary firewall serves as the main device managing traffic, implementing security policies, and providing the first line of defense against threats. High availability firewalls are designed to ensure minimal downtime and maintain functionality through redundancy—if one unit fails, another can take over seamlessly. Virtual firewalls operate in a virtualized environment, allowing organizations to secure their networks without dedicating physical hardware to each instance, enhancing flexibility and resource utilization.

These architectures reflect the strategic approaches organizations take to balance performance, reliability, and security demands in their network infrastructure. Understanding these frameworks helps in designing and implementing robust security postures aligned with organizational needs.
