Which Backup Data Center Site Best Balances Cost and a Two-Day RTO/RPO?

SY0-701 By islever Editorial Last updated

Short answer

D Warm

Question

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?
  1. Real-time recovery
  2. Hot
  3. Cold
  4. Warm Correct Answer

Key Takeaways

This question tests your ability to map disaster recovery site readiness levels to specific RTO/RPO thresholds while correctly interpreting 'cost-benefit' as total operational value rather than minimum upfront expenditure.

This question evaluates how different disaster recovery site types align with specific Recovery Time and Point Objectives (RTO/RPO) alongside budget constraints. The community consensus strongly favors a warm site, as it optimally balances moderate operational costs with a realistic two-day recovery window.

Common mistake: Candidates frequently select Cold site (C) by fixating on the lowest initial price tag and misreading 'cost-benefit' as synonymous with 'cheapest.' They overlook that cold sites lack pre-provisioned infrastructure and typically require weeks to months to activate, directly violating the two-day RTO/RPO requirement.

Expert Analysis

Core Concept: DR Site Readiness Tiers

Backup data centers are categorized by their level of equipment provisioning, data synchronization, and activation speed. Understanding these tiers is critical for matching business continuity requirements to organizational budgets.

Why Warm Site (D) is Correct

A warm site provides pre-installed hardware, networking, and environmental controls but lacks live data replication or fully configured systems. As noted by top-voted community members, it serves as the ideal middle ground: it can be operationalized within hours to a few days after a disaster, perfectly aligning with the stated two-day RTO/RPO. Furthermore, "cost-benefit" implies maximizing return on investment; paying slightly more upfront for a warm site prevents prolonged business disruption, making it far more beneficial than the absolute cheapest option.

Why Other Options Are Incorrect

  • Real-time recovery (A) and Hot sites (B) maintain continuous data mirroring and fully redundant infrastructure, enabling near-instantaneous failover. While they guarantee sub-hour RTOs, their exorbitant maintenance and power costs severely violate the "cost-benefit as the primary requirement" constraint.
  • Cold sites (C) offer only basic physical space with utilities. While they have the lowest upfront cost, they require vendors to ship, install, and configure all hardware before operations can resume. Community feedback correctly highlights that cold sites typically take weeks or months to stand up, making them incompatible with a 48-hour recovery target.

Exam Takeaway

When SY0-701 presents an RTO/RPO between 24 and 72 hours alongside budget considerations, a warm site is almost always the intended answer. Always prioritize the RTO constraint first, then let cost-benefit determine whether you scale up to hot or down to cold.

    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.

    or me is WARM, because two days isn't enough time to create a new DATA CENTER

    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.

    D. Warm A warm site is a middle ground between hot and cold sites. It typically contains some of the necessary infrastructure and data replication capabilities, but it's not as fully operational or costly as a hot site. In a warm site, some essential systems are ready to be activated quickly in the event of a disaster or disruption. This makes it suitable for scenarios where the RTO and RPO values are not immediate, such as in this case where they are around two days, while still being more cost-effective compared to a hot site.

    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?

    Based on the requirements, a Cold Site is the best option for the new backup data center. Here's why: - Cost-benefit is the primary requirement, and Cold Sites are the most cost-effective option compared to Hot or Warm Sites. - RTO (Recovery Time Objective) and RPO (Recovery Point Objective) values of around two days align with the characteristics of a Cold Site, which typically has a longer recovery time and data loss tolerance. - Cold Sites are designed for disaster recovery and business continuity, which aligns with the organization's requirement for a backup data center. Hot Sites are too expensive and have a shorter RTO and RPO, while Warm Sites are a compromise between Hot and Cold Sites but still more expensive than Cold Sites.

    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.

    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
  5. e5c1bb5 👍 2 Answered D
    definately not a cold site.. its the most cost effective but it could take weeks to get it running violating their goal of 2 day rpo and rto. cold sites are just buildings no equipment or software. a warm site might be more appropriate here? going with D here. please correct me if wrong.

    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.

    A cold site is the best option for the organization's requirements, balancing low cost with an acceptable two-day RTO and RPO, making it the most cost-effective solution.
  8. tsummey 👍 2 Answered D
    In my experience, a cold site will rarely, if ever, have a Recovery Time Objective (RTO) and a Recovery Point Objective (RPO) value of 2 days.

    I know it's warm site. But can I get an explanation way Real-time recovery is not a good option?

    Cost requirement is the "primary objective"
  11. ProudFather 👍 1 Answered A
    A cold site is the most cost-effective option for a backup data center because it is essentially an empty facility with basic utilities (e.g., power, cooling, and connectivity) but no active hardware or pre-installed systems. Since the organization has an RTO (Recovery Time Objective) and RPO (Recovery Point Objective) of around two days, a cold site is suitable as it provides enough time to set up and restore operations while keeping costs low.

    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. gpt

    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.

    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.
  15. edmondme 👍 1 Answered C
    Sorry folks I checked on this on the net and the answer is cold. The issue is that the organization is budget conscious so cold is cheaper than warm and cold is meant to take about 2 days. Warm is typically within hours.
  16. 201113e 👍 1 Answered C
    The correct answer is C. Cold (Site). The reason is because in the question it says that cost is the top priority. while warm sites are quicker to get up and running, they do cost more than a cold site.
  17. Turrtle 👍 1 Answered C
    If you need a balance between cost and recovery speed, a warm site is a good option. If cost is the main concern and downtime of a few days is acceptable, a cold site is better.

    Getting cold sites operational is typically measured in weeks. Getting things up and running in 2 days would almost certainly be a warm site.

    I think C is best answer. You can see line "cost-benefit as the PRIMARY requirement and RTO and RPO" on question.
