   A company runs a web application on a group of VMs. The workload is generally predictable, but there are occasional, short-lived spikes in traffic. The company has configured a dynamic scaling policy based on average CPU utilization. They notice that the policy is not reacting quickly enough to the spikes, causing performance degradation. What is the most effective way to improve the scaling policy's responsiveness?

   • AChange the scaling policy to a scheduled policy that adds VMs at the time of day when the spikes usually occur.
   • BDisable the scaling policy and manually add VMs when a spike is observed.
   • CUse a more sensitive metric, such as the request count per instance, and lower the threshold for triggering a scale-out.
   • DIncrease the cooldown period after a scaling activity.

   A company is decommissioning a database server that contains customer Personally Identifiable Information (PII). The company has a compliance requirement to ensure that the data cannot be recovered after the server is decommissioned. What is the most important step in the decommissioning process?

   • ATake a final backup of the database and store it in a secure, encrypted storage bucket.
   • BDisconnect the database from the application and leave it powered off.
   • CSecurely wipe or destroy the underlying storage volumes before or as part of the decommissioning process.
   • DDelete the virtual machine from the cloud console.

   A company runs a web application on a set of VMs behind a load balancer. The workload is variable, with predictable peaks during business hours and low traffic at night. The company wants to automate the process of adding and removing VMs to match demand without manual intervention. What should they configure?

   • AA scaling policy based on a single, static CPU utilization threshold of 50%.
   • BA scheduled scaling policy that increases the number of VMs at the start of business hours and decreases it at the end.
   • CA manual scaling process where an administrator reviews metrics and changes the VM count as needed.
   • DA load-balancer policy that distributes traffic evenly among existing VMs.

   Why is data sanitization important during the decommissioning of a cloud resource?

   • ATo reduce the cost of storage
   • BTo improve performance of the resource
   • CTo comply with software licensing agreements
   • DTo prevent unauthorized access to sensitive data
