A consumer project must access a managed service in a producer project privately using Private Service Connect. Which networking construct is NOT required for the consumer to reach the producer service?

Private Service Connect (PSC) allows consumers to access managed services privately without traversing the public internet. VPC Network Peering is not required because PSC establishes a private connection directly between the consumer's VPC and the producer's service. The consumer creates a PSC endpoint (a forwarding rule) that points to the producer's service attachment, which acts as the entry point for the service. The producer configures this service attachment to accept connections from specific projects or all projects. An RFC1918 IP address is allocated in the consumer's subnet for the PSC endpoint, making the service appear as if it's hosted within the consumer's VPC. VPC Network Peering is an alternative connectivity method, but it's not used in conjunction with PSC for this specific private access pattern.
