ACE Practice Question: A team deploys an application with sensitive…
This ACE practice question tests your understanding of a team deploys an application with sensitive…. 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 team deploys an application with sensitive internal APIs on GKE. The APIs should be reachable from other GKE services in the cluster and from on-premises systems via VPN, but not from the public internet. Which load balancer configuration meets this?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
A ClusterIP Service with an external IP range allowlist
ClusterIP Services are cluster-internal only — they're not reachable from on-premises systems, even via VPN.
B
Distractor review
NodePort Service with VPC firewall rules restricting access to VPN IP ranges
NodePort exposes a port on every node and requires the VPN client to know node IPs directly — not a scalable or clean solution for internal API exposure.
C
Best answer
Internal Application Load Balancer with a VPC-private IP
Internal ALBs receive a private RFC 1918 IP reachable within the VPC and connected networks (VPN, Interconnect). The service is never exposed to the public internet.
D
Distractor review
Global external Application Load Balancer with Cloud Armor blocking non-VPN IPs
External load balancers expose the service publicly — blocking IPs with Cloud Armor is fragile and doesn't truly restrict access to internal networks.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Internal Application Load Balancer with a VPC-private IP — An Internal Application Load Balancer (L7 internal) exposes the service with a private IP accessible within the VPC and connected networks (via VPN or Interconnect). External load balancers would expose the API to the internet. ClusterIP Services are accessible only within the cluster.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
