Which of the following technologies would reduce the risk that information is not accessible during a server crash?

The correct choice of server redundancy is particularly effective in reducing the risk that information is not accessible during a server crash. Server redundancy involves having multiple servers that can take over in the event of a primary server failure. This means that if one server goes down, another can seamlessly provide access to the same data and applications without any noticeable disruption to users.

By implementing server redundancy, organizations ensure continuous uptime and availability of their systems. This concept is crucial for maintaining operations in healthcare settings where patient data must always be accessible for timely decision-making and care processes. In contrast, while other technologies such as RAID, storage area networks, and backup solutions provide various levels of data protection and recovery options, they do not specifically address immediate accessibility during a server failure in the same proactive and real-time manner as redundancy does.

RAID, for example, focuses on data storage integrity and speed rather than providing an alternative server pathway during crashes. Storage area networks are about centralizing storage but may still depend on individual servers for access. Meanwhile, backup solutions, while crucial for data recovery after incidents, do not prevent inaccessibility during live operations when a crash occurs.
