   A database server currently uses 60% of its 16 GB RAM under normal load. Historical data shows that memory usage has been increasing by 5% per month for the past year. The administrator needs to predict when the server will run out of memory. What is the most appropriate method to estimate this?

   • AExtrapolate the monthly growth rate to estimate when usage will reach 100%.
   • BMonitor usage for another year before making any predictions.
   • CAssume memory usage will stay constant and plan for 60% usage.
   • DAdd 16 GB more RAM immediately to be safe.

   A company is planning to migrate its on-premises application to a cloud environment. The application's resource usage has been collected for the past six months. The administrator needs to estimate the cloud instance size required to handle the expected growth over the next year. Which approach best aligns with capacity planning methodologies?

   • ASelect the largest instance type available to ensure no performance issues.
   • BUse the peak usage from the past six months as the required capacity.
   • CUse the average usage from the past six months and add 10% as a safety margin.

   An administrator is monitoring a server that runs a batch job every night. The job's CPU usage has been increasing over time, and the administrator suspects it will eventually exceed the server's capacity. The administrator needs to predict when this will happen. What is the most appropriate method?

   • AUpgrade the CPU immediately to avoid any risk.
   • BAssume the CPU usage will stabilize and not grow further.
   • CWait until the CPU usage reaches 90% before taking action.
   • DUse the current CPU usage and the historical growth rate to project when it will reach 100%.

   A company is deciding whether to upgrade its current servers or move to a cloud-based solution. The administrator has collected resource usage data for the past year and needs to present a recommendation to management. The company values cost-effectiveness and flexibility. Which approach best supports the decision?

   • APresent the raw data and let management decide without a recommendation.
   • BRecommend moving to the cloud because it is always more cost-effective.
   • CModel the workload and compare the costs of upgrading versus cloud options, considering growth projections.
   • DRecommend upgrading the current servers based on the peak usage observed.
