```A model serving pod is failing with OOMKilled. What is the most likely cause?
⚠ Common exam trap
CompTIA often tests the distinction between OOMKilled (memory limit exceeded) and other pod failure reasons like CrashLoopBackOff (application crash) or ImagePullBackOff (image issues), so candidates must associate OOMKilled specifically with memory resource constraints, not general pod failures.
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
✓
The model requires more memory than the 2Gi limit
An OOMKilled error in Kubernetes indicates that a container exceeded its memory limit and was terminated by the Out Of Memory (OOM) killer. The most common cause is that the model's inference or training workload requires more memory than the configured resource limit (e.g., 2Gi), forcing the kernel to kill the process. This is a direct result of the container's memory request/limit mismatch with the actual consumption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The container image is corrupted
Why it's wrong here
OOMKilled indicates memory exhaustion, not image corruption.
- ✗
The model version is outdated
Why it's wrong here
OOMKilled is unrelated to model version; resource limits are the issue.
- ✓
The model requires more memory than the 2Gi limit
Why this is correct
The pod was killed because it used more memory than allowed.
- ✗
The Kubernetes cluster has run out of disk space
Why it's wrong here
Disk space issue would cause eviction, not OOMKilled.
