Answers

D.
Single point of failure
Answers
D.
Single point of failure
Suggested answer: D

Explanation:

The greatest concern with this situation is that a business-critical application does not currently have any level of fault tolerance and thus has a single point of failure. A single point of failure is a component or element of a system that, if it fails, will cause the entire system to stop functioning. Fault tolerance is the ability of a system to continue operating without interruption or degradation in the event of a failure of one or more of its components or elements. Fault tolerance can be achieved by using techniques such as redundancy, replication, backup, or failover. A business-critical application should have a high level of fault tolerance to ensure its availability, reliability, and continuity.Reference:
