Jerome needs to explain the key difference between high availability and fault tolerance to his management. What is the major difference between the two?
Answer Options
High availability is designed to avoid service interruptions almost entirely, whereas fault-tolerant environments have minimal service disruptions.
High availability provides services, whereas fault tolerance handles issues.
High availability focuses on data, whereas fault tolerance focuses on infrastructure.
High availability has minimal service interruptions, whereas fault-tolerant environments are designed to avoid service interruptions almost entirely.
Correct Answer: D
Explanation
High-availability designs are less expensive because they attempt to minimize service interruptions, whereas fault-tolerant designs seek to avoid service interruptions almost entirely, and thus cost significantly more. Both focus on service availability and typically use both hardware and software tools to meet their goals.
