An administrator is configuring service insertion for Network Introspection.
Which two places can the Network Introspection be configured? (Choose two.)
- A. Tier-1 gateway
- B. Partner SVM
- C. Host pNIC
- D. Tier-0 gateway
- E. Edge Node
正解：B、C
解説：
Explanation
Network Introspection is a service insertion feature that allows third-party network security services to monitor and analyze the traffic between virtual machines. Network Introspection can be configured on the host pNIC or on the partner SVM, depending on the type of service and the deployment model. The host pNIC configuration is used for services that require traffic redirection from the physical network to the service virtual machine. The partner SVM configuration is used for services that require traffic redirection from the virtual network to the service virtual machine. Network Introspection cannot be configured on the Tier-0 or Tier-1 gateways, as they are not part of the data plane where the service insertion occurs. Network Introspection also cannot be configured on the edge node, as it is a logical construct that hosts the Tier-0 and Tier-1 gateways.
