A WLAN (Wireless Local Area Network) is specifically defined as a network that uses radio frequency (RF) technologies , primarily Wi-Fi, to provide wireless connectivity. While technologies like infrared, Bluetooth, and ZigBee are wireless communication methods, they are not part of the WLAN definition.

Wi-Fi : Operates in the 2.4 GHz and 5 GHz frequency bands and is the primary technology used in WLANs.

Infrared : Uses light waves for short-range communication and is not part of WLAN standards.

Bluetooth : Designed for short-range personal area networks (PANs), not LANs.

ZigBee : Used for low-power, low-data-rate IoT applications, not WLANs.

Thus, the statement is FALSE , as WLANs are exclusively based on RF technologies like Wi-Fi.

Understanding Wi-Fi 6 AP Radios:

Wi-Fi 6 APs typically have two or three radios. Three-radio APs provide additional capacity and performance, making them ideal for high-density environments.

Analysis of Each Model:

AirEngine 5762-12:This model supportstwo radios(2.4 GHz and 5 GHz).

AirEngine 6761-21T:This model supportsthree radios, including an additional IoT radio for Internet of Things (IoT) applications.

AirEngine 5761-21:This model supportstwo radios.

AirEngine 5761-11:This model supportstwo radios.

Conclusion:The correct answer is Option B, as the AirEngine 6761-21T supports three radios.

A Wide Area Network (WAN) is designed to span large geographical areas, such as cities, regions, or even countries. WANs enable long-distance communication and are typically used to connect multiple Local Area Networks (LANs) or Metropolitan Area Networks (MANs). They rely on technologies like MPLS, SD-WAN, and leased lines to provide connectivity over vast distances.

The description provided in the question accurately reflects the characteristics and purpose of a WAN. Therefore, the statement is TRUE .

Overview of S5731-L Remote Units (RUs):

The S5731-L series includes remote units (RUs) designed for distributed campus networks. These RUs connect to a central switch via uplink ports.

Uplink Port Flexibility:

The RUs supportoptical, electrical, and hybrid optical-electrical ports, allowing flexible selection based on the distance between the RU and the central switch.

Optical ports are used for long-distance connections, while electrical ports are suitable for shorter distances. Hybrid ports combine both options for maximum versatility.

Conclusion:The statement is TRUE because the S5731-L RUs support multiple uplink port types for flexible deployment.
