- A
Enable cluster autoscaler to add more nodes
Why wrong: Doesn't address pod memory limits.
- B
Review container resource requests and limits in the pod YAML
OOMKilled indicates the container exceeded its memory limit.
- C
Check node memory utilization with kubectl top nodes
Why wrong: Nodes may have free memory; the issue is pod-level limits.
- D
Configure horizontal pod autoscaler based on memory
Why wrong: HPA adds replicas, doesn't increase memory per pod.

AZ-204 Practice Question: Monitor, troubleshoot, and optimize Azure solutions
This AZ-204 practice question tests your understanding of monitor, troubleshoot, and optimize azure solutions. 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.
You deploy a microservices architecture on Azure Kubernetes Service (AKS). Some pods report OOMKilled errors. Which diagnostic step should you take first?

Correct answer & explanation
✓
Review container resource requests and limits in the pod YAML
The OOMKilled error indicates that a container exceeded its memory limit. The first diagnostic step is to review the container's resource requests and limits in the pod YAML to determine if the memory limit is set too low for the workload. This directly addresses the root cause before scaling or checking node-level metrics.
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.
- ✗
Enable cluster autoscaler to add more nodes
Why it's wrong here
Doesn't address pod memory limits.
- ✓
Review container resource requests and limits in the pod YAML
Why this is correct
OOMKilled indicates the container exceeded its memory limit.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept

- ✗
Check node memory utilization with kubectl top nodes
Why it's wrong here
Nodes may have free memory; the issue is pod-level limits.
- ✗
Configure horizontal pod autoscaler based on memory
Why it's wrong here
HPA adds replicas, doesn't increase memory per pod.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often jump to scaling solutions (cluster autoscaler or HPA) or node-level monitoring, overlooking that OOMKilled is a container-level limit violation that must be diagnosed by examining the pod's resource configuration first.
Detailed technical explanation
How to think about this question
Under the hood, Kubernetes enforces memory limits via cgroups; when a container's memory usage exceeds its 'limits.memory' value, the OOM killer terminates the process. The 'kubectl describe pod' command can show the exact OOMKilled status and the container's resource spec, while 'kubectl top pod' reveals real-time memory usage. In a real-world scenario, a memory leak in the application code could cause gradual OOMKilled errors, and adjusting limits without fixing the leak only delays the issue.
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
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.
