- A
Configure an outbound DNS forwarding policy with Cloud Router to forward queries to on-premises DNS servers.
Why wrong: Outbound DNS policy is for forwarding queries from on-premises to GCP, not the other way.
- B
Create a DNS forwarding zone in Cloud DNS that points to the on-premises DNS server IPs via the Cloud Router.
This is the correct method: forwarding zone sends queries for the specified domain to on-premises DNS servers.
- C
Create a Cloud DNS private zone and add A records for each on-premises host.
Why wrong: This requires manually managing records, which is not scalable for dynamic on-premises environments.
- D
Set up a BIND server on a Compute Engine instance and configure it as a forwarder.
Why wrong: While possible, this is not the recommended managed service approach; Cloud DNS forwarding zone is the appropriate solution.
PCNE Implementing Hybrid Interconnectivity Practice Question
This PCNE practice question tests your understanding of implementing hybrid interconnectivity. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A company needs to resolve DNS queries from their Google Cloud VPC for on-premises hostnames (e.g., internal.mycompany.com). They have a Cloud VPN tunnel between GCP and on-premises. Which approach should they use?
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
Create a DNS forwarding zone in Cloud DNS that points to the on-premises DNS server IPs via the Cloud Router.
Cloud DNS forwarding zones allow you to forward queries for a specific domain (e.g., internal.mycompany.com) to on-premises DNS servers via the VPN tunnel.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
