You are deploying a new campus switching environment with various EX Series switch models. Devices connected to one of the new EX Series switches include IP phones, IoT devices, and wireless access points (APs) that require Power over Ethernet (PoE) with varying power requirements. A sample output from one of these switches is shown in the exhibit.

In this scenario, which two statements are correct?

Choose two
Explanation

A 2P/AT interface operates as IEEE 802.3at PoE+ over two pairs and can provide up to 30 W to a powered device. The (L) suffix on the 19.5 W maximum-power value denotes an LLDP-negotiated value, and the Class 4 value identifies the detected powered-device class; these are dynamically learned rather than statically configured.
