Cisco CCNA (200-301)Network FundamentalsEasy
A network technician is configuring an access point (AP) in a new office. The AP needs to support both 2.4 GHz and 5 GHz wireless clients simultaneously. Which type of access point is required?
- ASingle-band AP
- BWireless controller
- CDual-band AP
- DMesh AP
Show answer & explanationAnswer & explanation
Correct answer: C. Dual-band AP
A dual-band access point can operate on both the 2.4 GHz and 5 GHz frequency bands simultaneously, allowing it to serve a wider range of wireless clients and provide flexibility for different network needs.
Why the other options are wrong
- A. A single-band AP operates on only one frequency band (either 2.4 GHz or 5 GHz), not both simultaneously.
- B. A wireless controller manages multiple access points but is not an AP itself. It doesn't determine the band capabilities of the individual APs.
- D. A mesh AP is designed for creating a mesh network, which relates to how APs connect to each other, not necessarily the frequency bands they support. A mesh AP can be single or dual-band.
Dual-Band Access Point
A dual-band access point is a wireless access point that can transmit and receive on both the 2.4 GHz and 5 GHz Wi-Fi frequency bands simultaneously.
- Supports older 2.4 GHz (802.11b/g/n) and newer 5 GHz (802.11a/n/ac/ax) clients.
- Offers flexibility and can distribute client load across bands.
- 2.4 GHz provides greater range, 5 GHz provides higher speed and less interference.
Memory trick: AP bands are like radio stations: 2.4 is AM, 5 is FM, Dual-band is a combo.
