The following requirements were identified in an architecture workshop for a virtual infrastructure design project.
REQ001: All virtual machines must meet the Recovery Time Objective (RTO) of twenty-four hours or less in a disaster recovery (DR) scenario.
Which two test cases will verify these requirements?
RTO measures time to restore VMs after a DR event (24 hours here). Option B directly tests this: restoration within 24 hours meets the requirement. Option C tests data loss (RPO-like), but in DR context, ensuring no more than 24 hours of data loss complements RTO by verifying the recovery process's effectiveness, a common validation in VCF with tools like Site Recovery Manager (SRM). Option A (4 hours) is stricter than required, and D (4-hour data loss) tests RPO, not RTO. B and C align with VCF DR testing best practices.
