An administrator wants to deploy a VMware Cloud Foundation (VCF) VI Workload Domain (WLD). The WLD will use a vSAN stretched cluster across availability zones. What configuration step meets the requirements?
A.
Create a single host overlay network per availability zone with a DHCP scope
B.
Create a single host overlay network per availability zone with an IP Pool
C.
Create a site for the vSAN Witness by placing a single node ESXi host in the VI WLD
D.
Create a site for the vSAN Witness by placing a single node ESXi host in the management WLD
Stretched Cluster Requirements
vSAN stretched clusters in VMware Cloud Foundation have the following requirements:
• You must have a vSAN Enterprise license.
• The management domain cluster must be stretched before any VI workload clusters are stretched.
• Networking in both availability zones must meet the following requirements:
— The round-trip time (RTT) between availability zones must be less than or equal to 5 milliseconds.
— " Enough IP addresses must be available on the IP pool configured for the Host Overlay Transport in each availability zone. "
— The vSphere vMotion, vSAN, host overlay, and management networks must be stretched (L2) or routed (L3) between availability zones.
— The NSX Edge Uplink and NSX Edge Overlay Transport VLANs must be stretched (L2) across both availability zones.
Static Pool will not work for Streched Clusters

it depends on the version of VCF. for 5.1 and 5.2 there shouldn't be any restrictions. please take a look here:

Create a single host overlay network PER availability zone with an IP Pool.
It is mandatory to have separated NSX Host Overlay VLAN per site. take a look at Table 1 on the first link.
and it is recommended (best practice) to use Static IP pools for TEP. look at Table 3 and 4 on the second link.
