Reference the exhibit.
A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of
0.6ms as depicted by each line. An architect wants to configure a fault domain in each building.
What would the architect need change in order to implement a fully supported vSAN Cluster?
To implement a fully supported vSAN Cluster, it is necessary to enable a single Layer 2 network across all buildings for vSAN connectivity. This ensures that all nodes in different buildings are on the same Layer 2 domain and can directly communicate with each other, which is a fundamental requirement for vSAN to function correctly. Reducing RTT or adding redundant links would not address the Layer 2 network requirement, and enabling IPv6 is not relevant to the Layer 2 connectivity requirement.
I think B is correct. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-AFF133BC-F4B6-4753-815F-20D3D752D898.html
I think stretching the Layer2 network will be only the reconfiguration, required, because all Building as 2 Connectivity in a ring topology.
I think C is correct.
B. Site to site must be 5ms or less. Layer 2 is recommended and Layer 3 is supported. https://docs.vmware.com/en/VMware-vSphere/8.0/vsan-network-design-guide/GUID-F3401655-6EFA-477B-B072-E8F001B50BCC.html
Layer 2 is the basic network requirement
i cant see how this a supported config ? fault domains are for same site rack failure , so stretched cluster in which case will be 3 building not 4 ?
I believe the limit on VxRail 4.x is 3 fault domains. Native vSAN doesn't have that 3 fault domain limit.
