What indicators do Navy switches include?

• A. Power on/off; hardware indicator for hardware problems; software indicator for software problems.
• B. LED color; port speed; MAC address
• C. Temperature alert; humidity sensor; fan status
• D. Battery level; noise level; voltage

Answer: (A)

Indicators on Navy switches are meant to give a quick read of the device’s status. The three key signals you look for are whether the power is on, whether there’s a hardware fault, and whether there’s a software problem. The power indicator shows if the unit is receiving power. The hardware indicator alerts you to problems with physical components or modules. The software indicator flags issues with the switch’s firmware or software. Together, these tell you at a glance if the device is simply powered off, has a hardware fault, or has a software fault that needs attention.

Other options bring in items that aren’t standard health indicators on the switch face—for example, port speed and MAC address describe traffic data, not device health. Environmental readings like temperature, humidity, and fan status relate to hardware health but aren’t the primary indicator set used for a quick status check. Battery level, noise, and voltage aren’t typical indicators for network switches.
