Question #1318
Which AWS service or feature can be used to monitor network throughput spikes on a system running on Amazon EC2?
AWS CloudTrail
AWS Health Dashboard
AWS Trusted Advisor
Amazon CloudWatch
Explanation
Amazon CloudWatch (D) is designed to monitor AWS resources and applications in real time. It collects metrics like CPU utilization, network throughput (NetworkIn/NetworkOut), and disk performance for EC2 instances. Network throughput spikes can be tracked using CloudWatch metrics and alarms.
Why other options are incorrect:
- A. AWS CloudTrail: Focuses on auditing API calls and user activity, not performance metrics.
- B. AWS Health Dashboard: Provides status updates on AWS service outages, not resource-level monitoring.
- C. AWS Trusted Advisor: Offers cost/security optimization recommendations, not real-time metric tracking.
Key Points:
- CloudWatch is AWS's primary monitoring tool for performance metrics.
- EC2 sends network metrics to CloudWatch by default (e.g., NetworkIn, NetworkOut).
- Use CloudWatch alarms/dashboards to detect and analyze throughput spikes.
Answer
The correct answer is: D
