Exam SY0-601 topic 1 question 428 discussion

Uninterruptible power supplies with battery backup would be the most cost-effective solution for the data center to implement in order to deal with the increase in under-voltage events and occasional losses of system availability. The battery backup would provide short-term power during an outage or under-voltage event until power is restored or a generator is started. While managed power distribution units, a generator, and dual power supplies are all potential solutions, they are likely to be more expensive and may not be as effective in addressing under-voltage events.

Managed power distribution units (PDU) can help in detecting power outages but an interrupted power supply (UPS) will help in recovering from an outage by providing a power backup. UPS is also cheaper than a generator but will provide less power and for a shorter duration.

wow, i think this is the first time ive seen CompTIA not use the acronym when there is one. UPS is correct.

Though I hv chosen A but there is still some confusion:

Easily A

The most cost-effective solution for the data center to implement in response to an increase in under-voltage events would be A. Uninterruptible power supplies (UPS) with battery backup. A UPS provides backup power to systems in the event of a power failure or voltage fluctuation. By installing UPS units with battery backup, the data center can ensure that its systems remain available even during under-voltage events.

-A The most cost-effective solution for the data center to implement in the given scenario would be to install Uninterruptible Power Supplies (UPS) with battery backup. UPS systems provide backup power to critical systems in the event of power interruptions, brownouts, or blackouts. The battery backup feature of a UPS can provide power to the data center for a short period of time, allowing time for a generator to be started or for systems to be properly shut down to prevent data loss or damage. Managed power distribution units (option B) would provide information about the under-voltage events but would not address the underlying issue. It may be helpful to track these events, but it will not prevent the occasional losses of system availability. Dual power supplies (option D) can distribute the load more evenly, but they do not address the issue of under-voltage events caused by power grid maintenance. Additionally, adding dual power supplies may also require additional infrastructure and equipment, resulting in higher capital and operational costs.c
