   Which feature is a benefit of using Cloud Run?

   • AIt requires you to provision virtual machines for each instance.
   • BIt requires you to manage the underlying Kubernetes cluster.
   • CIt only supports applications written in a single programming language.
   • DIt provides portability because it runs standard containers.

   A media company runs a thumbnail-generation service that is triggered whenever a new video is uploaded. Upload volume varies wildly: a few per day normally, but hundreds per hour during a product launch. The team has no dedicated operations staff. Which serverless service is best suited for this event-driven workload?

   • ACloud Run, which requires the team to build a container image for the thumbnail logic
   • BApp Engine, which requires the team to configure scaling parameters for the service
   • CCloud Functions, which runs code in response to upload events and scales automatically
   • DA Compute Engine VM with a cron job that polls for new uploads

   A startup is deciding between two architectures for a new API: a serverless service that scales to zero, and a small VM that runs 24/7. The API will have very low traffic for the first six months, then is expected to grow. The startup's main concern is minimizing costs during the initial period while ensuring the API can handle future growth. Which factor most strongly favors the serverless option?

   • AServerless guarantees higher performance than a VM for all workloads
   • BServerless provides a fixed monthly cost that is easier to budget
   • CServerless charges only for actual requests, avoiding idle VM costs during the low-traffic period
   • DServerless eliminates the need for a load balancer and firewall configuration

   A startup is building a mobile app backend that processes image uploads. The workload is highly unpredictable: sometimes no requests for hours, then sudden bursts of thousands. The team has only two developers and wants to avoid any infrastructure maintenance. Which approach best matches these requirements?

   • APurchase a reserved capacity commitment for a fixed number of vCPUs to guarantee availability
   • BProvision a Compute Engine VM with autoscaling configured and a load balancer in front
   • CRun the backend on a Kubernetes cluster with a node pool that can scale down to zero
   • DDeploy the backend as a serverless service that scales to zero and charges only for actual invocations
