Cisco CCNA (200-301)Network FundamentalsEasy
A network technician is installing a new wireless access point (AP) in a warehouse. The AP needs to provide both 2.4 GHz and 5 GHz wireless connectivity to support a variety of client devices. Which type of access point should the technician select?
- ADual-band AP
- BPowerline AP
- CSingle-band AP
- DMesh AP
Show answer & explanationAnswer & explanation
Correct answer: A. Dual-band AP
A dual-band access point is specifically designed to operate on and support client connections on both the 2.4 GHz and 5 GHz frequency bands simultaneously, meeting the requirement for both types of connectivity.
Why the other options are wrong
- B. A Powerline AP uses electrical wiring to transmit network data, which is unrelated to wireless frequency bands.
- C. A single-band AP operates on only one frequency band (either 2.4 GHz or 5 GHz), not both.
- D. A Mesh AP is designed for extending wireless coverage without wired backhaul, not specifically for dual-band operation.
Dual-band Access Point
An access point capable of broadcasting Wi-Fi signals on both the 2.4 GHz and 5 GHz frequency bands simultaneously.
- 2.4 GHz offers greater range and penetrates walls better, but is more prone to interference.
- 5 GHz offers higher speeds and less interference, but has shorter range.
- Supports legacy and modern wireless devices, providing flexibility.
Memory trick: Dual means Two Bands, Single just One, Mesh for Extension, Powerline via Wire.
