Which of the following is NOT a feature of the Ethernet Switch (Cysco Catalyst C3560)?

The correct answer is based on the fact that the Cisco Catalyst C3560 switch is primarily designed for wired networking and does not include native wireless connectivity features. This switch model is focused on providing high-performance switching capabilities for Ethernet networks, which typically involve the connection of wired devices.

The mode button, for instance, is a common feature in many switch models, including the C3560. This button is used for facilitating the configuration and management of the switch, allowing administrators to switch between different operational modes.

Additionally, the C3560 is well-equipped with 10/100 Fast Ethernet ports that can support Power over Ethernet Plus, which allows for the delivery of electrical power along with data over the same cable to connected devices, enhancing its functionality for devices such as IP phones and wireless access points.

Moreover, this switch also supports 1 Gigabit Ethernet ports, allowing for higher-speed connectivity over a typical Ethernet connection, making it suitable for environments that demand more bandwidth.

In summary, by noting that the Cisco Catalyst C3560 does not support wireless connectivity, it becomes clear why this feature would be marked as not applicable to this specific switch model.
