Question 14

A hot site is the most suitable option for quick failover.

A hot site is an exact replica of the primary site, equipped with all necessary hardware and software, allowing for immediate operation in the event of a primary site failure. This type of site ensures minimal downtime, making it ideal for recovery strategies requiring swift transitions.

A) Recovery site

While a recovery site indicates a location designated for backup operations, it does not specify the readiness level of the site. A recovery site could be any type of backup facility, including cold or warm sites, which may not provide the immediate failover capability required in this scenario.

B) Hot site

A hot site is fully operational and can take over operations immediately with no lag time, making it the best choice for a quick failover strategy. It has all necessary systems and data replicated and synchronized with the primary site, ensuring continuity of service.

C) Cold site

A cold site is essentially a backup facility that has the necessary infrastructure but lacks the immediate operational capability, as it does not have up-to-date data or operational systems ready to go. This option would result in significant downtime before operations could resume, making it unsuitable for the requirement.

D) Warm site

A warm site is partially equipped and can be used for recovery but requires some configuration and data updates before it can be fully operational. This leads to longer recovery times compared to a hot site, which is not ideal for a strategy that needs quick failover.

Conclusion

The hot site is the definitive choice for a recovery strategy requiring quick failover due to its operational readiness and complete data synchronization. Other options, such as cold and warm sites, do not provide the immediate capabilities necessary for minimizing downtime, thereby failing to meet the engineer's needs for rapid recovery.
