The following requirements were identified in an architecture workshop for a virtual infrastructure design project. REQ001: All virtual machines must satisfy the Recovery Point Objective (RPO) of fifteen (15) minutes or less in a disaster recovery (DR) situation REQ002: Service level availability must satisfy 99.999% measured yearly. Which two test cases will validate these requirements?

REQ001 specifies an RPO of 15 minutes or less, meaning the maximum data loss in a DR scenario is 15 minutes. REQ002 demands 99.999% availability, but test cases focus on DR validation, so RPO is primary here. Option C directly tests RPO: if VMs lose no more than 15 minutes of data, the requirement is met, aligning with vSphere Replication or vSAN stretched clusters in VCF 5.2, which can achieve such RPOs. Option A tests restoration within 15 minutes, which, while related to Recovery Time Objective (RTO), also implies minimal data loss if achieved, indirectly validating RPO in a failover context. Option B (1 hour of data loss) exceeds the 15-minute RPO, failing REQ001.
Option D (1-hour restoration) tests RTO, not RPO, and isn’t tied to data loss limits. VCF DR solutions emphasize these metrics, making A and C the precise validations.
