   A company runs a web application on-premises with a load balancer that distributes traffic to three web servers. During a marketing campaign, traffic is expected to double for one week. The company wants to burst additional web servers into the cloud. The cloud web servers must be able to access the same session data stored on-premises. What must be configured to support this burst?

   • AEnsure the cloud web servers can reach the on-premises session store over the private network connection and that the load balancer includes them in the pool.
   • BConfigure the cloud web servers to store session data locally on their own instance storage.
   • CDeploy a second load balancer in the cloud and configure it to handle all traffic during the campaign.
   • DUse a public DNS service to route users to the cloud web servers based on their geographic location.

   A software company runs a legacy monolithic application on a single VM in a private cloud. The company wants to move this application to a public cloud provider with minimal changes to the application code. Which mobility mechanism is most appropriate for this scenario?

   • APerform a VM migration by exporting the virtual disk and importing it into the target cloud's VM service.
   • BUse a container registry to package the application and deploy it with a container orchestration platform.
   • CReinstall the application from source code on a new VM in the target cloud and reconfigure it manually.
   • DRefactor the application into microservices and deploy each as a container in the target cloud.

   An online ticketing company sells tickets for major concerts. Ticket sales open at a specific time and generate a massive, short-lived spike in traffic that lasts about 30 minutes. The company's on-premises infrastructure is sized for normal sales volume. Which bursting scenario is most appropriate for this workload?

   • APre-provision cloud instances before the on-sale time and keep them running for the duration of the spike, then release them.
   • BUse a reactive autoscaling policy that adds instances only after CPU utilization exceeds 80% for 10 minutes.
   • CMigrate the entire application to the cloud permanently to avoid the need for bursting.
   • DConfigure the on-premises load balancer to send all traffic to the cloud during the spike and none afterward.
