Reveal correct answer
Correct answer: B
Explanation
Correct Answer: B. Redundancy
Redundancy is the concept of designing systems with duplicate components so that if a failure were to occur, there would be a backup. In the context of a data center, redundancy can be applied to several aspects including utility service entrances, power supplies, and even generators.
Incorrect Answers:
A. Scalability refers to the ability of a system to increase its capacity to handle more load. It doesn't inherently provide backup for failed components.
C. Microsegmentation is a network design principle that helps prevent lateral movement of threats within the network by creating isolated segments with granular security controls. It doesn't provide backup for failed components.
D. Virtualization is the process of creating a software-based (or virtual) representation of something rather than a physical one. It doesn't inherently provide backup for failed components.
