Topic #: 2
Several storms cause mission-critical servers to go offline unexpectedly A server also goes offline suddenly due to haroNvare failure Upon assessment the company purchases new UPSs to condition power and allow the OSs to shut down gracefully in the event of a power failure However, the UPSs are delayed due to supply chain issues Which of the following can balance a cost-effective solution with uptime requirements?
C . Installing redundant PSUs (Power Supply Units):
Redundant PSUs provide fault tolerance by ensuring that if one power supply fails, another will take over seamlessly.
This is a cost-effective way to increase uptime while waiting for the UPSs to arrive.
Incorrect Options:
A . Purchasing backup generators: Generators are costly and are typically used for long-term outages, not as an immediate or cost-effective solution.
B . Increasing input voltage: This is not a practical solution to hardware failures or power issues.
D . Activating a hot site: A hot site is an expensive, fully operational backup facility that would not be a cost-effective solution for this scenario.
Key Takeaway: Installing redundant PSUs is a cost-effective way to balance uptime requirements in case of power or hardware failure. Reference: CompTIA A+ Core 1 Exam Objectives (220-1101), Domain 5.3 -- Power-related troubleshooting.
