Which of the following would BEST allow this to happen?
A.
Add a redundant power supply to the switch B.
Implement stacking on the switches in the rack C.
Add a second UPS into the rack D.

A.
The correct answer is A. Add a redundant power supply to the switch.
Explanation:
A UPS (Uninterruptible Power Supply) is a device that provides backup power to a network device in case of a power outage. When a UPS fails, it needs to be replaced, which may require the device attached to it, such as a switch, to be taken offline. This can result in a network outage and affect the availability of the network.
To prevent this from happening, the network administrator can add a redundant power supply to the switch. A redundant power supply is a second power supply unit that is connected to the switch and provides backup power in case the primary power supply fails. By having a redundant power supply, the network administrator can replace a defective UPS without taking the switch offline.
Option B, Implement stacking on the switches in the rack, is incorrect as it is not related to the issue of UPS maintenance. Stacking allows multiple switches to be managed as a single entity, but it does not provide backup power to the switches.
Option C, Add a second UPS into the rack, is also incorrect as it does not address the issue of taking the switch offline for maintenance. Adding a second UPS may provide backup power to the switches, but it does not allow for UPS maintenance without taking the switch offline.
Option D, Install a power converter for the switch, is incorrect as it does not provide backup power to the switch. A power converter is a device that converts one type of power to another, such as AC power to DC power, but it does not provide backup power.
