What type of network joins two independent computer networks to engage communication between them?

• A. Bridged network
• B. Mesh network
• C. VPN tunnel
• D. Hub network

Answer: (A)

Joining two independent networks so devices can communicate is achieved by a bridged network. A bridge connects two LAN segments at the data-link layer, learning MAC addresses and forwarding frames only to the segment where the destination MAC is known. This makes the two pieces behave like one network and keeps them within the same broadcast domain, so devices on either side can talk directly without routing between different IP networks. A VPN tunnel, by contrast, creates a secure IP path over an external network and relies on routing and encryption; a mesh network emphasizes multiple interconnections for redundancy rather than simply linking two networks; and a hub simply repeats signals, which doesn’t properly join two networks or manage traffic between them.
