Exam 2V0-41.23 topic 1 question 64 discussion

East-West Service Insertion, the insertion points are at each guest VM’s vNIC.

North-South Service Insertion for Network Introspection can be applied at Tier-0 and Tier-1 gateways. The insertion points are the uplinks of the Tier-0 or Tier-1 gateways

Answer 1 by filtration and elimination. B => not the same network layer in the OSI model C => don't know what is it, it's seems not a feature D => SVM is for monitoring in other thing, and it deployed on the Vcenter, so seems irrelevant with the question

I Think is A: North-South Service Insertion for Network Introspection can be applied at Tier-0 and Tier-1 gateways. The insertion points are the uplinks of the Tier-0 or Tier-1 gateways. A partner service virtual machine (SVM) is deployed close to the NSX Edge node to process the redirected traffic. The SVM virtual appliance is connected over the service plane to receive redirected traffic. https://www.ramyafifi.com/post/micro-segmentation-with-nsx-data-center

D. Partner SVM https://docs.vmware.com/en/VMware-NSX/4.1/administration/GUID-53D6C480-7AD3-4B23-922D-430C89992B57.html

I will go with A as this is where the rules to redirect the traffic is applied making it the point of insertion

D. Partner SVM According to the VMware NSX Documentation, Partner SVM is a valid insertion point for north-south network introspection. Network introspection is a feature that allows you to insert third-party network services into the data path of your traffic. Partner SVM stands for Partner Service Virtual Machine and is a virtual appliance that runs on an NSX Edge node and provides network services from a partner solution.
