Question 180
Before changing switch configuration, an engineer investigates: An access closet requires both redundant power and PoE for cameras. Which FIRST check is most useful for isolating the cause?
Explanation
Correct Answer
Inspect switch power status and actual per-port PoE consumption. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that power planning includes endpoint draw and switch supply redundancy.
Incorrect Answers
This diagnostic choice fits a different situation: A fiber uplink between two buildings never reaches operational up state. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect switch power status and actual per-port PoE consumption.
This diagnostic choice fits a different situation: A remote rack has uplink ports but inconsistent link speeds and duplex behavior. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect switch power status and actual per-port PoE consumption.
This diagnostic choice fits a different situation: Two switches must exchange VLAN 20 and VLAN 30 but a user in VLAN 30 cannot cross the uplink. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect switch power status and actual per-port PoE consumption.
