The correct answer is A. Tell the customer cloud A is the best solution. Cloud A's disaster recovery solution fully meets the customer's requirements, offering an RPO of 5 minutes (within 15 minutes) and an RTO of 1 hour (within 24 hours).
Question
A cloud administrator is managing two private cloud environments. In cloud A, the disaster recovery solution has an SLA for RPO of five minutes and RTO of one hour. In cloud B, the disaster recovery solution has an SLA for RPO of one hour and RTO of 24 hours. A new customer's application requires that, in case of a disaster, no more than 15 minutes of data can be lost, and it should be fully recovered within one day. Which of the following would be the BEST approach to this application?
Options
- ATell the customer cloud A is the best solution
- BPut it in cloud B and ask the customer to create snapshots every 15 minutes
- CBoth cloud A and cloud B would suit the customer's needs
- DChange the cloud B disaster recovery solution so RPO will be 15 minutes

Why each option
Cloud A's disaster recovery solution fully meets the customer's requirements, offering an RPO of 5 minutes (within 15 minutes) and an RTO of 1 hour (within 24 hours).
Cloud A has an RPO of five minutes and an RTO of one hour. This meets the customer's requirements of no more than 15 minutes of data loss (5 < 15) and recovery within one day (1 hour < 24 hours).
Cloud B's RPO of one hour does not meet the customer's 15-minute RPO requirement; asking the customer to manage snapshots is not part of the cloud provider's SLA.
Cloud B's RPO of one hour significantly exceeds the customer's acceptable data loss of 15 minutes, making it unsuitable.
Changing Cloud B's DR solution is a major infrastructure modification and not an immediate 'best approach' for placing an application in an existing environment.
