Refer to the exhibit. Considering Transport Zone limitations, how many NSX managed virtual distributed switches (N-VDSs) are needed on each ESXi to join all the Transport Zones?
sorry.. A is correct...
An NSX virtual switch (N-VDS or VDS with NSX) can attach to a single overlay transport zone and multiple VLAN transport zones at the same time.
A transport zone can only be attached to a single NSX virtual switch on a given transport node. In other words, two NSX virtual switches on the same transport node cannot be attached to the same transport zone.

"You can use the same N-VDS to link to multiple transport zones. I.e Single N-VDS can carry the traffic of both the Overlay transport zone and the VLAN transport zone."
This is realy hard question. I'm not sure which answer is good for 100%. We can create only single N-VDS per TZ. But it doesn't say that we can't use the same N-VDS in couple of TZs. In the table attached to this question we can see that every N-VDS has the same name. So the most probably answer is D.
Correct Answer is D:

About Transport Nodes
In NSX-T transport nodes are the hosts running the local control plane daemons and forwarding engines implementing the NSX-T data plane. A transport node runs a NSX-T Virtual Distributed Switch (N-VDS) that is responsible for switching packets according to the configuration of available network services.
A host can serve as a transport node if it contains at least one NSX-T-managed virtual distributed switch (N-VDS). When you create a host transport node and then add the node to a transport zone, NSX-T Data Center installs an N-VDS on the host. For each transport zone that the host belongs to, a separate N-VDS is installed. The N-VDS is used for attaching VMs to NSX-T Data Center logical switches and for creating NSX-T Data Center logical router uplinks and downlinks.
I think the D is correct simply because when join transport node to these Transport Zones TZ, these TZ will create these N-VDS into the Host, now N-VDS can only support only one type of traffic either overlay or VLAN, and Esxi host can not have two N-VDS with the Same name, but one N-VDS on Esxi host can attach to Overlay and VLAN simultaneously. so 1 N-VDS on Esxi will be sufficient. and 2 can not be created as here both TZ traffic type Overlay and VLAN has the same switch name. Thats my understanding i would be thankful if someone endorse it?
