A public-health dashboard must survive losing a single worker node that hosted one of its Pods. Which design choice most directly improves that resilience?
Select an answer to reveal the explanation.
Short Explanation
One Pod on one node is a single point of failure—spread a few replicas and a node loss is a dent, not an outage. Leaving one lonely Pod with hostNetwork does not buy you high availability.
Full Explanation
Replica count greater than one allows surviving Pods on other Nodes to continue serving when one Node or Pod fails, especially when combined with a Service. A single Pod cannot tolerate node loss regardless of hostNetwork. Disabling readiness or using Never restartPolicy worsens availability rather than improving it.
