AWS Certified SysOps Administrator – Associate (SOA-C03) — Question 71

A CloudOps engineer is using AWS Compute Optimizer to generate recommendations for a fleet of Amazon EC2 instances. Some of the instances use newly released instance types, while other instances use older instance types.

After the analysis is complete, the CloudOps engineer notices that some of the EC2 instances are missing from the Compute Optimizer dashboard.

What is the likely cause of this issue?

Answer options

• A. The missing instances have insufficient historical Amazon CloudWatch metric data for analysis.
• B. Compute Optimizer does not support the instance types of the missing instances.
• C. Compute Optimizer already considers the missing instances to be optimized.
• D. The missing instances are running a Windows operating system.

Correct answer: B

Explanation

The correct answer is B because AWS Compute Optimizer may not support the newer instance types, leading to their absence from the dashboard. Option A is incorrect as lacking historical data would not prevent instances from appearing; rather, it would affect their analysis. Option C is not valid because the absence of instances does not imply they are already optimized. Option D is also incorrect since Compute Optimizer supports instances running on Windows.
