A. B. C. D. E.AE.
The Services Router (SR) is a critical component of the Tier-0 Gateway in VMware NSX-T Data Center, responsible for handling traffic routing and providing advanced services such as NAT, load balancing, and firewalling.
The correct statements about the characteristics of the Services Router (SR) component of a Tier-0 Gateway are as follows:
B. SR can exist on both hypervisor transport nodes and Edge transport nodes: The Services Router (SR) can be deployed on either hypervisor transport nodes (ESXi hosts) or Edge transport nodes (physical appliances or virtual machines). When deployed on a hypervisor transport node, the SR acts as a logical router on the host, providing East-West traffic routing between VMs. When deployed on an Edge transport node, the SR provides North-South traffic routing between the data center and external networks.
E. SR can be created from the NSX Advanced Networking & Security tab in the UI: The Services Router (SR) can be created from the NSX Advanced Networking & Security tab in the UI, using the "Add Tier-0 Gateway" wizard. During the gateway creation process, you can specify the deployment type of the SR, either on a hypervisor transport node or an Edge transport node.
Therefore, options A, C, and D are incorrect.
A. Edge cluster is mandatory for SR to be created: An Edge cluster is not mandatory for the creation of a Services Router (SR) component of a Tier-0 Gateway. You can deploy the SR on either a hypervisor transport node or an Edge transport node.
C. SR is automatically created when stateful services are enabled: The Services Router (SR) component of a Tier-0 Gateway is not automatically created when stateful services are enabled. The SR must be created explicitly using the NSX Advanced Networking & Security tab in the UI.
D. Edge transport nodes are required for SR to be created: The Services Router (SR) component of a Tier-0 Gateway can be deployed on either hypervisor transport nodes or Edge transport nodes. Therefore, Edge transport nodes are not required for the SR to be created.
