   What is serverless computing?

   • AA model where the cloud provider manages the servers and automatically scales resources
   • BA model where you must provision and scale servers yourself
   • CA model where you manage your own virtual machines but without an operating system
   • DA model where you rent physical servers without any virtualization

   A research organization runs a large-scale data processing job that analyzes genomic data. The job is divided into thousands of independent tasks, and if any task fails, it can be re-run without affecting the overall result. The organization has a limited budget and wants to reduce compute costs as much as possible. What is the most appropriate compute option?

   • AUse preemptible VMs to run the tasks, with a mechanism to re-queue any tasks that are interrupted.
   • BUse a serverless platform to run each task as a separate function invocation.
   • CUse standard VMs with a high-memory configuration to ensure tasks complete quickly.
   • DProvision a dedicated GPU cluster to accelerate the processing and reduce the number of VMs needed.

   What is a key advantage of using serverless computing compared to virtual machines?

   • AServerless provides the highest level of control over the underlying operating system.
   • BServerless is the best choice for long-running, stateful applications.
   • CServerless requires you to manage container orchestration.
   • DServerless eliminates the need to provision or manage servers.
