The most suitable type of power supply for a server requiring continuous availability is A. Redundant. A redundant power supply provides a backup power source, ensuring that the server remains operational even if one of the power supplies fails. This is crucial for maintaining the server's availability. GG

Selected Answer: A
Modular, switched-mode, and semi-modular power supplies are not as suitable for applications that require continuous availability. Modular power supplies allow you to add or remove power supply modules as needed, but they are not as reliable as redundant power supplies. Switched-mode power supplies are the most common type of power supply, but they are not as efficient as redundant power supplies. Semi-modular power supplies are a hybrid of modular and non-modular power supplies, but they are not as reliable as redundant power supplies.
