Upon connecting a VMware Managed Transit Gateway (VTGW), the administrator discovers that there is an overlapping workload CIDR bleck. How will the software-defined data center (SDDC) handle the overlapping IP space?
A.
It will reject the remote IP space.
B.
It will isolate the overlapping segment in the cloud.
C.
It will allow the overlapping IP space.
D.
It will ensure both CIDR blocks work in both locations.

Workload CIDRs should not overlap – if they do, remote overlapping networks are rejected.
- Workload CIDRs should not overlap;if they do, remote overlapping networks are rejected.
- Note that the overlapping compute segments would not be advertised and are excluded from the vTGW route table

If the overlapping ranges are excluded from the vTGW route table and are not advertised to vTGW by SDDC, it will ensure that both CIDR blocks work in both locations?
A is Correct. Is clear in the documentation

SDDCs must be at release 1.11 or higher
SDDCs and VPCs that are members of a SDDC group MUST be in the same region
SDDC management CIDRs MUST not overlap
SDDC networks shouldn’t overlap but if they do, know that overlapping segments won’t be advertised
B
The requirements to use VMware Transit Connect are as follows:
• SDDCs must be at release 1.11 or later.
• SDDCs and VPCs that are members of a SDDC group must be in the same region.
• SDDC management CIDRs must not overlap.
• SDDC networks should not overlap. If they do overlap, the overlapping segments are not advertised.

I think the answer should be A.
