Your company is planning to deploy a critical server infrastructure that must maintain high availability. As a security architect, you are responsible for recommending a solution to ensure that the infrastructure remains operational in the event of a power outage. Which of the following would provide the best protection?
You selected this option
Establish a large array of battery banks to provide additional power.
You selected this option
Implement redundant power supplies in each critical server.
You selected this option
Use surge protectors to prevent damage from power surges.
You selected this option
Install an Uninterruptible Power Supply (UPS) for the critical servers.
An Uninterruptible Power Supply (UPS) provides backup power to the infrastructure in the event of a power outage, ensuring the servers remain operational until either the main power is restored or a longer-term solution like a generator can take over. Surge protectors, while they protect against voltage spikes, do not provide power during an outage. Redundant power supplies ensure the servers can continue to operate if one power supply fails, but they require power from an external source and will not protect against an outage. Battery banks can store power but generally do not switch as rapidly as a UPS to provide uninterrupted power.
