Building-permits engineers cannot create new Pods because the namespace CPU budget is exhausted. Which object enforces that namespace-level ceiling at admission?
Select an answer to reveal the explanation.
Short Explanation
ResourceQuota is the namespace credit limit—when the CPU budget is spent, admission says no to new Pods. HPA scales replicas; it is not the namespace budget enforcer.
Full Explanation
ResourceQuota tracks and limits aggregate resource use (and object counts) within a namespace; admission rejects creates/updates that would exceed the quota. HPA adjusts replica counts for a workload and does not replace namespace quota. EndpointSlices and scheduler webhooks are not the standard namespace budget mechanism.
