- A
Cloud NAT
Why wrong: Cloud NAT is for outbound internet access, not site-to-site connectivity.
- B
Dedicated Interconnect
Why wrong: Dedicated Interconnect offers high availability but is a physical connection requiring colocation; it is more expensive and complex than HA VPN.
- C
HA VPN with BGP
HA VPN offers a 99.99% SLA, dynamic routing via BGP, and high availability through two tunnels.
- D
Classic VPN with static routing
Why wrong: Classic VPN has no SLA and static routing is less flexible.

Google ACE Planning and Configuring a Cloud Solution Practice Question
This ACE practice question tests your understanding of planning and configuring a cloud solution. 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.
An organization wants to set up a hybrid cloud connection between their on-premises data center and Google Cloud VPC. They need high availability (99.99% SLA) and support for dynamic routing. Which connection method 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
✓
HA VPN with BGP
HA VPN provides a 99.99% SLA, supports dynamic routing via BGP, and offers two tunnels for redundancy. Dedicated Interconnect also offers high availability but is a physical connection with higher cost. Partner Interconnect is similar to HA VPN but also physical. Classic VPN has no SLA.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related ACE NAT questions on configuration and troubleshooting.
