Topic 1 Question 322
A SysOps administrator is responsible for a legacy, CPU-heavy application. The application can only be scaled vertically. Currently, the application is deployed on a single t3.large Amazon EC2 instance. The system is showing 90% CPU usage and significant performance latency after a few minutes.
What change should be made to alleviate the performance problem?
Change the Amazon EBS volume to Provisioned IOPs.
Upgrade to a compute-optimized instance.
Add additional t2.large instances to the application.
Purchase Reserved Instances.

B (I hope Gomer agree with me and he is okay)
👍 2koltysh2023/06/29Since the application is CPU-heavy and can only be scaled vertically, the best option to alleviate the performance problem would be to upgrade to a compute-optimized instance. Compute-optimized instances provide a higher ratio of vCPUs to memory than other families and are optimized for compute-bound applications that benefit from high-performance processors. Upgrading to a compute-optimized instance would provide more CPU resources for the application, which should help alleviate the performance problem.
So, the correct answer would be B. Upgrade to a compute-optimized instance.
