An organization is building a new backup data center with cost-benefit as the primary requirement and RTO and RPO values around two days. Which of the following types of sites is the best for this scenario?
Warm Sites
● Not fully equipped, but fundamentals in place
● Can be up and running within a few days
● Cheaper than hot sites but with a slight delay
Cold Sites
● Fewer facilities than warm sites
● May be just an empty building, ready in 1-2 months
● Cost-effective but adds more recovery time
A warm site offers a balance between cost-effectiveness and recovery time objectives (RTO) and recovery point objectives (RPO). It typically has some pre-installed infrastructure and data backups but may require additional configuration and data restoration before becoming fully operational. Given the RTO and RPO values of around two days, a warm site provides a reasonable compromise between cost and recovery capability.
A cold site is the most cost-effective option because it provides basic infrastructure, such as a physical space with power, cooling, and network connectivity, but it does not have active IT systems or pre-configured data.
Cold sites typically require time to set up the necessary systems, which aligns with the two-day RTO/RPO requirements. They are less expensive compared to hot or warm sites because they do not have pre-installed equipment or active data replication.
A cold site provides the best balance between cost and the organization's relatively long RTO/RPO requirements (two days).
A warm site has some infrastructure pre-configured and can be brought online faster than a cold site, but it is more expensive. This would be suitable for a scenario where RTO and RPO are shorter than two days, but it's overkill for this case.
Cost-benefit doesn't mean the cheapest. What is more beneficial paying cheapest possible for a cold site, and taking possible weeks to get it up and running or paying mid-range for a warm site that can be brought online in hours to a couple of days?
A warm site strikes a balance between cost and recovery time. It typically has hardware and connectivity set up, but systems and data may not be fully up-to-date. This setup allows the organization to recover within the specified RTO and RPO of around two days without the high costs associated with a hot site.

A warm site offers a balance between cost-effectiveness and recovery speed. While it requires some setup and data restoration during a disaster, this can usually be accomplished within the two-day RTO and RPO window specified by the organization.
It is most certainly a warm site. With cost benefit being the primary objective, meaning the benefits should outweigh the cost, a warm site is the best option. With the cold site, you don't have any equipment or servers, nor you have any network connectivity and it might take a long time to switch that into a fully functional site that might exceed two days. While it might be the cheapest option, but it will certainly cost you a fortune if the business operations cannot be recovered back to normal within the required RPO and RTO range.
In the scenario where the organization's primary requirement is cost-benefit, and the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) values are around two days, the best type of site for the backup data center would be a Cold site.
C. Cold
A cold site is the most cost-effective option for a backup data center when the primary requirements are cost-benefit and RTO (Recovery Time Objective) and RPO (Recovery Point Objective) values around two days. A cold site is a backup facility that has the necessary infrastructure (such as power and space) but no active IT systems or data until it is needed. This makes it less expensive than hot or warm sites, which are partially or fully equipped with active systems and data replication.
Therefore, the correct answer is:
C. Cold
