One type of router is a ___ router.

• A. Dual-band
• B. Wireless
• C. Hard-wired
• D. Interconnected

Answer: (A)

Routers are often described by the number of wireless frequency bands they support. A dual-band router can operate on two frequency bands—typically 2.4 GHz and 5 GHz—at the same time. This gives you options: devices that need longer range can connect on the 2.4 GHz band, while faster, less crowded 5 GHz offers higher throughput for bandwidth-intensive devices. It’s a specific type that communicates a clear capability, unlike simply saying the router is wireless (many routers are wireless, but that’s a general feature rather than a distinct type). A hard-wired router implies no wireless capability, which is not the case for most modern setups, and “interconnected” isn’t a standard router type. Because the question highlights a classifier based on frequency support, a dual-band router is the best-fit description.
