PCNE Configuring Network Services Practice Question
Which TWO network services are required to enable private Google access for on-premises hosts using a Dedicated Interconnect connection? (Choose two.)
⚠ Common exam trap
Google Cloud often tests the misconception that Cloud NAT is needed for private access, but the trap here is that Cloud NAT is for outbound internet from VMs, while Private Google Access for on-premises uses BGP-advertised IP ranges and does not involve NAT.
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
✓
Cloud Router with BGP
Cloud Router with BGP is required because Dedicated Interconnect uses BGP sessions between the on-premises router and Google's edge router to exchange routes. Without BGP, the on-premises network cannot advertise or receive the routes necessary for private Google access, such as the 199.36.153.4/30 or 199.36.153.8/30 ranges used for Private Google Access for on-premises.
