Selected Answer: B

A Pod Disruption Budget (PDB) allows you to specify the minimum number or percentage of Pods that must be available during voluntary disruptions such as node drains during upgrades. By configuring a PDB with a minAvailable value of 10%, Kubernetes ensures that at least 10% of your application’s Pods remain available when nodes are being drained, thereby meeting your high-availability requirement.
