   A company runs a real-time analytics platform on-premises. The platform has a steady baseline load, but occasionally experiences unpredictable spikes that last 1-2 hours. The company has a limited budget and cannot afford to keep idle cloud capacity running. The application is stateful and requires low-latency access to an on-premises data store. Which bursting strategy best balances cost and responsiveness?

   • AMove the entire application to the cloud permanently to eliminate the need for bursting.
   • BUse a purely reactive autoscaling policy that provisions instances from zero only after the spike is detected.
   • CPre-provision a large number of cloud instances before any potential spike and keep them running at all times.
   • DPre-provision a small pool of cloud instances that are always on, and scale out reactively within that pool when a spike is detected.

   A financial services company runs a loan-origination application on-premises. During the last week of each month, loan application volume spikes to 4x the normal rate for 3 days, overwhelming the on-premises infrastructure. The company wants to handle these predictable peaks without permanently expanding the on-premises footprint. Which approach directly addresses this requirement?

   • APurchase additional on-premises servers and keep them powered on year-round to handle the peak load.
   • BConfigure the application to automatically deploy additional compute instances in the public cloud during the peak period and scale back down afterward.
   • CMigrate the application permanently to a public cloud region and decommission the on-premises environment.
   • DUse a content delivery network to cache static loan-application assets and reduce origin load during the peak.
