Question
The following requirements were identified in an architecture workshop for a VMware Cloud Foundation (VCF) design project using vSAN as the primary storage solution:
REQ001: The application must maintain a minimum of 1,000 transactions per second (TPS) during business hours, excluding disaster recovery (DR) scenarios. REQ002: Automatic DRS and HA must be utilized. REQ003: Planned maintenance must be performed outside of business hours. While monitoring the TPS of the application, which of the following is NOT a valid test case to validate these requirements?
Options
- ATrigger a vSphere High Availability (HA) failover activity.
- BTrigger a vSAN disk group cache drive failure.
- CTrigger fully automatic DRS vMotion activity.
- DTrigger a vCenter upgrade workflow.

Explanation
The test case must validate all three requirements: maintaining 1,000 TPS during business hours (REQ001), using automatic DRS and HA (REQ002), and ensuring maintenance occurs outside business hours (REQ003, implying minimal disruption during business hours). Let's assess each: Option A: Trigger a vSphere High Availability (HA) failover activity HA failover (e.g., host failure) tests automatic VM restarts (REQ002) and ensures TPS (REQ001) remains at 1,000 during business hours under failure conditions (excluding DR, as this is intra- site). The VCF 5.2 Administration Guide recommends HA testing to validate availability, making Option B: Trigger a vSAN disk group cache drive failure A cache drive failure in vSAN tests data resilience and HA's ability to restart VMs if needed (REQ002), while monitoring TPS (REQ001) during business hours. The vSAN Administration Guide supports this as a standard test for vSAN performance and recovery, aligning with the Option C: Trigger fully automatic DRS vMotion activity Fully automatic DRS triggers vMotion to balance loads (REQ002), testing TPS (REQ001) during business hours without disruption. While not maintenance, it validates DRS automation's impact on performance, per the vSphere Resource Management Guide, making it a valid test. Option D: Trigger a vCenter upgrade workflow A vCenter upgrade is a planned maintenance activity (REQ003) that should occur outside business hours. Performing it during business hours to monitor TPS contradicts REQ003 and isn't a typical test for DRS/HA (REQ002) or application performance (REQ001), as it affects management, not workloads directly. The VCF 5.2 Administration Guide treats upgrades as separate from runtime validation.
