Explanation
Network infrastructure devices are the hardware components that facilitate communication across a network. Routers direct traffic between different networks using IP addressing and routing protocols. Switches connect devices within a local area network (LAN) and forward traffic based on MAC addresses. Firewalls enforce security policies by filtering traffic between network segments. All three are foundational components of network infrastructure, making 'All of the above' the complete and correct answer. Each plays a distinct role in network architecture and is commonly tested on CompTIA Network+, Security+, and similar certifications.
