Exam 3V0-23.25 Topic 1 Question 72 Discussion

Actual exam question for VMware's 3V0-23.25 exam
Question #: 72
Topic #: 1

A VCF Architect is designing a hybrid environment. The plan is to stretch a 16-node vSAN cluster across two sites.
The hosts also mount 50 TB of Supplemental Fibre Channel (FC) LUNs to support legacy databases.
```
[vSAN Performance / Topology View]
Cluster: VCF-Stretched-01
Principal Storage: vSAN Datastore (Dual Site Mirrored)
Supplemental Storage: Legacy-FC-Datastore
```
How do the vSAN Stretched Cluster prerequisites intersect with the capabilities of the traditional Fibre Channel storage in this unified cluster? (Select all that apply.)

A. SDDC Manager automatically configures the external FC array for Dual Site Mirroring using the VASA Provider. B. For the VMs on the FC Datastore to survive a site failure, the underlying physical FC array must also support a native synchronous array-stretching feature (e.g., SRDF/Metro) with Active/Active presentation to both sites. C. vSphere HA requires consistent datastore visibility across the cluster; if the FC LUN is NOT stretched (only visible to Site A), vSphere HA will fail to restart the legacy DB VMs on Site B if Site A fails. D. While vSAN can tolerate up to 5ms RTT on the Inter-Site Link, the synchronous Fibre Channel stretch requirement is typically much stricter (< 1ms RTT), dictating the lowest common denominator for the ISL network prerequisite. E. vSAN handles the "Site A to Site B" synchronous mirroring natively through the ESXi kernel, independent of the external SAN array.
