A network engineer notices that a PoE-powered IP phone intermittently loses power. The switch shows the port's power consumption is close to the configured limit. What is the most likely cause and solution?

The switch's PoE budget is exhausted; disable PoE on unused ports

The power limit is set too low; increase the port's power limit

The cable is too long; use a shorter cable

The phone is faulty; replace the phone

Which Junos CLI configuration statement enables PoE on a specific interface?

A university is deploying a mix of devices on a switch with a 740W PoE budget. The administrator has configured 10 ports for 60W devices, 20 ports for 30W devices, and 10 ports for 15.4W devices. The total demand is 600W + 600W + 154W = 1354W, which exceeds the budget. The administrator wants to ensure that the 60W devices are always powered, but also wants to maximize the number of 30W devices powered. What is the best strategy?

Set all ports to 'high' priority

Set the 60W ports to 'critical' priority and the 30W ports to 'high' priority

Increase the power limit on the 60W ports

A switch has a PoE budget of 370W. The administrator has configured 24 ports with a priority of 'low' and 4 ports with 'high'. If the total demand exceeds the budget, which ports will be powered first?

The ports with the lowest power consumption
