Exam SY0-701 topic 1 question 50 discussion

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.

Explanation: A cold site is a type of backup data center that has the necessary infrastructure to support IT operations, but does not have any pre-configured hardware or software. A cold site is the cheapest option among the backup data center types, but it also has the longest recovery time objective (RTO) and recovery point objective (RPO) values. A cold site is suitable for scenarios where the cost-benefit is the primary requirement and the RTO and RPO values are not very stringent. A cold site can take up to two days or more to restore the normal operations after a disaster. Reference = CompTIA Security+ SY0-701 Certification Study Guide, page 387

A cold site is the most cost-effective option because it provides the necessary infrastructure but lacks pre-configured hardware, software, or active data replication. Given the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) of around two days, a cold site is suitable since it allows for recovery within that timeframe while keeping costs low.

RTO and RPO values around two days are generally associated with a cold site. A cold site is a backup facility that typically has minimal or no hardware equipment installed, making it cost-effective but requiring time to set up after a disaster. In contrast, hot sites have fully configured hardware and software, enabling faster recovery with lower RTOs and RPOs. Warm sites offer a middle ground with some hardware and software pre-installed.

D. Warm Site: Again another ambiguous Q/A.. and could be cold site, though Cold sites have only basic infrastructure, space, power and cooling..you need servers/networking to restore to the RPO/RTO hence it has to WARM Site Type Setup Readiness Data Freshness RTO Cost Hot Site Fully operational Real-time / near-real-time Minutes to hours Very High Warm Site Partial setup Hours to days old Hours to a day Moderate Cold Site Bare minimum None (must be restored) Days to weeks

With an RTO and RPO around 2 days, and cost-benefit as a priority, a cold site is the best fit.

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.

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.

warm site

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.

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.

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

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.
