Palo Alto Networks Cybersecurity Entry-Level Technician (PCCET) — Question 106

Which network device breaks networks into separate broadcast domains?

Answer options

• A. Hub
• B. Layer 2 switch
• C. Router
• D. Wireless access point

Correct answer: C

Explanation

A router is the correct answer because it operates at Layer 3 of the OSI model and is responsible for routing packets between different broadcast domains. In contrast, a hub and a Layer 2 switch operate within the same broadcast domain, and a wireless access point simply extends the local network without segmenting it.
