Cisco CCNA (200-301)Network FundamentalsMedium
A network administrator is designing a new wireless network for a small office. They want to ensure that client devices have access to both 2.4 GHz and 5 GHz wireless bands from a single access point. Which type of access point should they deploy?
- ADual-band access point
- BWireless controller
- CPower over Ethernet (PoE) injector
- DSingle-band access point
Show answer & explanationAnswer & explanation
Correct answer: A. Dual-band access point
A dual-band access point operates simultaneously on both the 2.4 GHz and 5 GHz frequency bands, allowing client devices to connect to either band based on their capabilities and network conditions.
Why the other options are wrong
- B. A wireless controller manages multiple access points but is not an access point itself.
- C. A PoE injector provides power to an access point over Ethernet but does not determine its operating frequency bands.
- D. A single-band access point operates on only one frequency band (either 2.4 GHz or 5 GHz), not both.
Dual-Band Access Point
A dual-band access point is a wireless device that can transmit and receive signals on both the 2.4 GHz and 5 GHz frequency bands simultaneously.
- Supports both 2.4 GHz (longer range, more interference) and 5 GHz (higher speed, less interference).
- Allows clients to connect to the optimal band.
- Common in modern wireless deployments.
Memory trick: Two bands, two frequencies, one access point: dual-band delight!
