Exam AWS Certified SysOps Administrator - Associate topic 1 question 42 discussion

Exam question from Amazon's AWS Certified SysOps Administrator - Associate
Question #: 42
Topic #: 1
[All AWS Certified SysOps Administrator - Associate Questions]

A company has migrated its application to AWS. The company will host the application on Amazon EC2 instances of multiple instance families.
During initial testing, a SysOps administrator identifies performance issues on selected EC2 instances. The company has a strict budget allocation policy, so the
SysOps administrator must use the right resource types with the performance characteristics to match the workload.
What should the SysOps administrator do to meet this requirement?

  • A. Purchase regional Reserved Instances (RIs) for immediate cost savings. Review and take action on the EC2 rightsizing recommendations in Cost Explorer. Exchange the RIs for the optimal instance family after rightsizing.
  • B. Purchase zonal Reserved Instances (RIs) for the existing instances. Monitor the RI utilization in the AWS Billing and Cost Management console. Make adjustments to instance sizes to optimize utilization.
  • C. Review and take action on AWS Compute Optimizer recommendations. Purchase Compute Savings Plans to reduce the cost that is required to run the compute resources.
  • D. Review resource utilization metrics in the AWS Cost and Usage Report. Rightsize the EC2 instances. Create On-Demand Capacity Reservations for the rightsized resources.

Selected Answer: C
A and B are incorrect as purchasing RI before performing rightsizing is nonsense. C is the most likely to be correct, but it does not state anything on rightsizing actions. However purchasing Compute Savings Plans allows to make rightsizing later. D - incorrect, as On-Demand Capacity Reservations has nothing to budget.

D The SysOps administrator should review resource utilization metrics in the AWS Cost and Usage Report, rightsize the EC2 instances, and create On-Demand Capacity Reservations for the rightsized resources in order to meet this requirement. This will allow the administrator to identify the EC2 instances that are experiencing performance issues, and resize them to the optimal instance family based on their workload. Creating On-Demand Capacity Reservations will also ensure that the company has access to the necessary compute resources without exceeding its budget allocation. Options A, B, and C are not appropriate for this situation, as they do not involve rightsizing the EC2 instances to match the workload.
