   Your Virtual Machine Scale Set is configured with autoscale rules that scale out when CPU exceeds 70% and scale in when CPU drops below 30%. You notice that the scale set is 'flapping' - scaling out and then immediately scaling in. You need to stabilize the autoscale behavior. What should you configure?

   • ADecrease the threshold for scale-out to 60% and increase the threshold for scale-in to 40%
   • BUse a single autoscale rule that combines both scale-out and scale-in conditions
   • CIncrease the cooldown periods for both scale-out and scale-in rules
   • DRemove the scale-in rule and only keep the scale-out rule
