Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A service attachment in the producer VPC that points to a load balancer
Private Service Connect requires a service producer to create a service attachment (which uses a load balancer as the backend), and consumers to create Private Service Connect endpoints. The producer must also enable Private Service Connect on the subnet where the load balancer resides.

A service attachment in the producer VPC that points to a load balancer
Why this is correct
The service attachment is the published service endpoint.
