Question #1050
Which AWS service offers rightsizing recommendations for Amazon EC2 instances at no additional cost?
AWS Trusted Advisor
AWS Budgets
AWS Systems Manager
AWS Config
Explanation
The correct answer is A. AWS Trusted Advisor offers rightsizing recommendations for EC2 instances by analyzing utilization metrics (e.g., CPU, memory, network) to identify underutilized or overprovisioned instances. These recommendations are part of Trusted Advisor's cost optimization checks, available at no additional cost for all AWS customers (with some limitations based on support plans).
Why other options are incorrect:
- B. AWS Budgets: Focuses on cost tracking and alerts, not optimization recommendations.
- C. AWS Systems Manager: Manages operational tasks and automation, not rightsizing guidance.
- D. AWS Config: Tracks resource configuration history and compliance, not performance-based optimization.
Key Point: Trusted Advisor is AWS's built-in tool for cost-saving recommendations, including EC2 rightsizing, without extra charges beyond standard AWS usage fees.
