ACE Practice Question: Your application is deployed on GKE and…
This ACE practice question tests your understanding of your application is deployed on gke and…. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Your application is deployed on GKE and experiencing increased latency. You suspect a memory leak causing the JVM to run frequent garbage collection cycles. Cloud Monitoring shows high memory usage but you need to understand the garbage collection behavior over time. Which GCP tool provides JVM-level profiling including memory allocation data?
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
Best answer
Cloud Profiler with heap profiling enabled for the JVM application.
Cloud Profiler captures CPU and memory profiles from production JVMs with minimal overhead (<1% CPU impact). Heap profiling shows memory allocation patterns and identifies the source of leaks.
B
Distractor review
Error Reporting filtered for OutOfMemoryError exceptions.
Error Reporting captures exceptions after they occur. If the JVM crashes with OOM, Error Reporting captures it — but profiling is needed proactively before a crash to identify the leak.
C
Distractor review
Cloud Trace
Cloud Trace measures request latency across distributed services. It doesn't provide JVM-level memory or garbage collection profiling.
D
Distractor review
Cloud Monitoring with JVM MBeans metrics exported via the Ops Agent.
Exporting JVM metrics shows high-level GC counts and heap sizes but not detailed allocation profiles. Cloud Profiler provides the call-stack-level allocation data needed for leak diagnosis.
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: Cloud Profiler with heap profiling enabled for the JVM application. — Cloud Profiler is a GCP service that continuously profiles production applications with low overhead. It supports CPU profiling, heap profiling, and memory allocation profiling for Java (JVM), Go, Python, Node.js, and Ruby. For JVM memory leak investigation, enabling heap profiling in Cloud Profiler shows which objects are consuming memory and where allocations are occurring — helping identify the source of the leak.
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.
