30. Which of the following non-production sites is an operational mirror of the primary data center and is ready for use if the primary data center experiences an outage?
Answer: A
Hot
A hot site is an operational mirror of the primary data center, fully equipped and ready for immediate use in the event of an outage. This type of site ensures minimal downtime and data loss, making it an ideal choice for critical operations.
A) Hot
This option is correct because a hot site provides real-time data replication and has all necessary hardware and software in place, allowing for immediate failover. It is designed specifically for quick recovery, making it a crucial component of disaster recovery strategies.
B) Warm
A warm site is partially equipped and may have some data replication capabilities, but it is not fully operational at all times. It requires some time to become fully functional, which could lead to extended downtime during an outage, thus making it less suitable for immediate recovery compared to a hot site.
C) Cold
A cold site lacks immediate operational capability and typically requires significant time to set up and restore data from backups. This option is not appropriate for situations where an immediate response is necessary, as it cannot provide the quick transition needed during a data center outage.
D) Frozen
A frozen site is not a standard term used in disaster recovery contexts. It typically refers to a state where systems or processes are paused or halted, but it does not represent a viable option for recovery in the event of an outage, making it irrelevant to the question.
Conclusion
The hot site is definitively the best answer as it guarantees immediate operational readiness and minimizes downtime during outages. Other options, such as warm and cold sites, either lack the necessary immediacy or operational readiness, while the term "frozen" does not apply in this context. Thus, hot sites are essential for maintaining business continuity in critical situations.
