The Deployment c3-unschedulable requests 500Gi of memory, which exceeds the node's allocatable memory, causing the pod to be unschedulable due to insufficient memory.

expected root cause — the answer key
The pod cannot be scheduled because it requests 500Gi of memory, which no node can satisfy. The cause appears only in a FailedScheduling event, not in any metric.
This is never shown to the model. It is what the grader compared the diagnosis against, and it is on this page because a demo that showed only the answer would be asking you to take the grading on trust.

model output — its reasoning, and the tools it asked for
**Findings** | # | Category | Confidence | Hypothesis | Evidence | |---|----------|------------|------------|----------| | 1 | resource‑limit | 0.95 | The `c3-unschedulable` Deployment requests **500 Gi** of memory (`memory=500Gi`) which far exceeds the node’s allocatable memory, so the pod is rejected with “Insufficient memory”. | • Event: `0/1 nodes are available: 1 Insufficient memory.` (step 01a05ef7-9404‑7fa0‑b885‑d1e5cf0d243f) <br>• Deployment spec shows request `memory=500Gi` (step 01a05ef7-b4fa‑7807‑947c‑9508a984f3de) | **Summary** The pod cannot be scheduled because its memory request of 500 Gi is larger than any node’s available memory. The scheduler reports “Insufficient memory”, and the Deployment manifest confirms the oversized request. Reducing the memory request (or limits) to a value that fits within the node’s allocatable resources will allow the pod to be placed successfully.

plan
The pod is unschedulable because the Deployment requests an impossible amount of memory (500 Gi). This is a configuration issue that must be corrected by a human editing the Deployment spec; no automated action can safely resolve it.
No action was proposed. The planner set no_action_required — which is the expected outcome for most incidents, and what the planning prompt tells it to default to.
