Exam FC0-U61 topic 1 question 515 discussion

A. Redundant equipment Explanation: Redundant equipment (e.g., backup servers, network devices, power supplies) ensures high availability by minimizing downtime in case of hardware failure. This is often the most cost-effective method compared to setting up a full disaster recovery site or implementing an extensive continuity plan. Why Not the Others? B. Disaster recovery site – While effective, setting up a separate recovery site is costly and typically used for mission-critical operations. C. Continuity plan – A business continuity plan is important for long-term resilience but does not directly increase availability in real-time. D. Scheduled maintenance – Regular maintenance prevents failures, but it does not directly improve availability since maintenance often requires downtime. Thus, redundant equipment (A) is the best cost-effective choice to increase availability.

Scheduled maintenance because regular maintenance helps prevent unexpected failures, ensures optimal system performance, and extends equipment lifespan, all at a lower cost compared to redundant systems or disaster recovery sites. vs Redundant equipment increases availability, it is more expensive.

D. Scheduled maintenance
