Question

what is required to maintain a high degree of reliability and eliminate single points of failure?
accessibility
expandability
redundancy
integrity

Explanation:

• Accessibility refers to the ease with which a system or resource can be accessed. It is not directly related to eliminating single - points - of - failure.
• Expandability is about the ability to increase the capacity or functionality of a system. It does not address reliability in terms of single - points - of - failure.
• Redundancy involves having duplicate components or systems. If one component fails, the redundant one can take over, thus eliminating single - points - of - failure and maintaining reliability.
• Integrity is about the accuracy and consistency of data. It is not focused on system reliability in the context of single - points - of - failure.

Answer:

C. Redundancy
