A Nexus 1000v is installed with the VSM in a switching module and the VEM in a cloud environment. Which statement is incorrect about the VSM and VEM?
A. VLANs can be shared with multiple VSM installations.
B. VSM module requires three interfaces such as management, control and packet.
C. VSM L3 mode uses IP address to communicate with VEM.
D. SVS domain ID can be same with multiple VSM installations.
my bad, typo.
i mean correct answer is D (incorrect statement)
correct answer is B (incorrect statement)
In L3 mode, the VSM only needs the control interface and mgmt interface for use putty ssh port 2.
Verifying the Domain Configuration
The Virtual Supervisor Module (VSM) and Virtual Ethernet Module (VEM) are separated within a Layer 2 domain. To allow VSM-VEM pairs to communicate within the same Layer 2 domain, each pair must have a unique identifier. The domain ID serves as the unique identifier that allows multiple VSM-VEM pairs to communicate inside the same Layer 2 domain.

The question is asking for the INCORRECT statement. Answer B is correct as per Cisco DOC below:
The Nexus 1000V VSM VM has 3 network interfaces.
Control (control0)
Management (mgmt0)
Packet

Agreed. As for the correct INCORRECT answer… think it is D per the following documentation.
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus1000/sw/4_0/system_management/configuration/guide/n1000v_sys_manage/system_2domain.html
This outlines creating the SVS domain which woud allow shared vlans on multiple VSMs.
“•You must have a unique domain ID for this Cisco Nexus 1000V instance.”
I suppose the indication isn’t exactly explicitly stated but it seems like a reasonable conclusion from a best practices perspective as configuring identical SVS domains a capability will resut in a lost capability.
