   A team is deploying a Spot VM for a fault-tolerant batch job. What is the recommended way to handle the preemption lifecycle?

   • AUse a managed instance group with a target size to automatically recreate the Spot VM after preemption
   • BConvert the Spot VM to a standard VM after it starts to avoid preemption
   • CSet a lifecycle policy on the VM to prevent preemption from occurring
   • DConfigure the VM to automatically restart itself after preemption without any external orchestration

   Which practice is a core principle of resource optimization for cost efficiency?

   • AEliminating idle resources that are no longer needed
   • BKeeping all resources running 24/7 to avoid any potential downtime
   • COver-provisioning resources to ensure maximum performance at all times
   • DUsing the largest machine type available for every workload

   A team wants to reduce the cost of Cloud Monitoring for a large fleet of virtual machines. Which approach directly addresses the cost of monitoring metrics?

   • AStore all monitoring data in BigQuery for long-term analysis
   • BDeploy additional monitoring agents to collect more granular metrics from each VM
   • CCreate more alerting policies to catch anomalies earlier
   • DUse Monitoring filters to exclude low-value metrics from ingestion and reduce the number of custom metrics created

   A company runs a production web application on a fleet of 20 n2-standard-4 VMs that operate 24/7. The workload is stable and has not changed in the past year. The team wants to reduce costs while maintaining the same capacity. What is the most effective strategy?

   • APurchase a 1-year or 3-year committed-use discount for the 20 VMs, matching the region and machine type.
   • BRely on the sustained-use discount that automatically applies to the VMs after running for most of the month.
   • CDownsize the VMs to n2-standard-2 and rely on the recommender to confirm the new size is sufficient.
   • DMigrate the VMs to Spot VMs to get the largest possible discount, since the application is stable.

   What is a key lifecycle management practice to reduce Compute Engine costs for a non-production environment that is only used during business hours?

   • ADelete the VMs and recreate them from a snapshot every day
   • BUse a larger machine type to ensure the VMs can handle the morning workload spike
   • CKeep the VMs running 24/7 to avoid any potential startup delays
   • DSchedule the VMs to stop during off-hours and start before business hours begin
