   A company runs a web application that experiences unpredictable traffic spikes. The application is deployed on a group of VMs behind a load balancer. During a spike, the load balancer sends traffic to all VMs, but some VMs become overloaded while others remain underutilized. The administrator wants to ensure that all VMs are used efficiently during spikes. What should the administrator do?

   • AUse a round-robin algorithm to distribute traffic evenly by rotation.
   • BConfigure autoscaling to add more VMs when CPU utilization exceeds 70%.
   • CIncrease the size of all VMs to handle the maximum possible load.
   • DChange the load balancer algorithm to least-connections so traffic is sent to the VM with the fewest active connections.

   A cloud administrator needs to allocate resources for a new application that has predictable, steady-state usage. Which allocation approach is most appropriate for this scenario?

   • ADeploy on spot instances to reduce cost
   • BAllocate the minimum resources and rely on manual scaling when needed
   • CUse a serverless function that scales automatically with each request
   • DProvision a fixed set of resources sized to the expected peak demand

   A company runs a stateless web application on multiple VMs. The administrator wants to ensure that if a VM fails, traffic is automatically redirected to healthy VMs, and the application remains available. What should the administrator configure?

   • AAn autoscaling policy that adds a new VM when CPU utilization is high.
   • BA load balancer with a health check that automatically removes unhealthy VMs from the rotation.
   • CA DNS record with a short TTL that points to all VM IP addresses.
   • DA scheduled task that reboots each VM every hour.
