   A company is evaluating whether to migrate a production workload from on-demand VMs to reserved instances. The workload runs 24/7 and is not expected to change for the next 3 years. The finance team requires a cost-benefit analysis. The administrator calculates that reserved instances would save 40% compared to on-demand, but the company would need to commit to a 3-year term. What is the most important additional factor the administrator should consider in the analysis?

   • AThe performance difference between reserved and on-demand instances.
   • BThe ease of migrating to a different cloud provider in the future.
   • CThe risk of the workload being decommissioned or significantly changed before the commitment ends.
   • DThe current utilization of the VMs to ensure they are not over-provisioned.

   A company runs a web application that experiences variable traffic. The administrator wants to ensure the application always has enough capacity during traffic spikes, but also wants to minimize cost during low-traffic periods. The administrator has configured autoscaling, but notices that during rapid spikes, the application becomes slow before new instances are ready. What should the administrator do to improve the scaling response?

   • ADisable autoscaling and manually add instances when traffic increases.
   • BSet up a scheduled scaling action that adds instances just before the expected spike time.
   • CReduce the instance size so new instances launch faster.
   • DConfigure a larger cooldown period between scaling actions to avoid thrashing.

   A cloud administrator notices that a database VM has been running at 90% memory utilization for several weeks, while CPU utilization is only 10%. The application is experiencing occasional out-of-memory errors. The administrator wants to resolve the issue cost-effectively. What should the administrator do first?

   • AIncrease the memory of the VM to a larger instance type that provides more RAM.
   • BAdd another VM and use load balancing to distribute the database workload.
   • CEnable autoscaling to add a second VM when memory utilization exceeds 80%.
   • DReduce the CPU size to a smaller instance type to lower costs.
