PCNE Configuring network services Practice Question
This PCNE practice question tests your understanding of configuring network services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO network services are required to enable private Google access for on-premises hosts using a Dedicated Interconnect connection? (Choose two.)
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Cloud Router with BGP
Why this is correct

✗
Cloud NAT
Why it's wrong here
NAT is for internet egress, not for private Google access.
✗
VPC Flow Logs
Why it's wrong here
Flow logs are not required for connectivity.
✓
Private Service Access (PSA) / Private Google Access for on-premises
Why this is correct
This feature allows on-premises hosts to reach Google APIs via private IPs.

Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Private Google Access for on-premises works by having on-premises hosts send DNS queries for googleapis.com to a specific IP range (199.36.153.4/30 or 199.36.153.8/30) that is advertised via BGP over the Interconnect. The Cloud Router then redistributes these routes into the VPC, and the on-premises router must also advertise the on-premises CIDR to Google. This setup relies on RFC 4271 BGP-4 for route exchange and requires the Cloud Router to be configured with the appropriate BGP peer IPs and ASN.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
