SAP-C02 Question 462
Select 3Your company runs a mission-critical application on AWS. The application is distributed across multiple EC2 instances in an Auto Scaling group behind an Application Load Balancer. The development team wants to monitor the application’s performance and ensure quick detection of issues such as increased response times, dropped requests, or high error rates. They also require the ability to trigger automated actions based on these metrics. Which combination of AWS services and features should you use to satisfy these requirements?
- A
Amazon CloudWatch Alarms to monitor specific metrics like response time and error rates and trigger automated actions.
- B
Amazon CloudTrail to log all API calls and detect performance issues in real-time.
- C
Amazon CloudWatch Synthetics to simulate user traffic and monitor application endpoints for availability and performance.
- D
AWS Config to ensure Auto Scaling group configurations remain compliant with defined policies.
- E
Amazon CloudWatch Logs to collect and analyze application logs for error patterns and anomalies.
- F
Amazon GuardDuty to monitor the application for potential security threats.
Show answer and explanation
Correct answers: A, C, E
Explanation
To effectively monitor the application’s performance and ensure quick detection of issues, you need a combination of monitoring tools that focus on metrics, synthetic traffic simulation, and log analysis. Amazon CloudWatch Alarms provide real-time insights into key metrics and enable automated responses. Amazon CloudWatch Synthetics simulates user interactions to detect performance problems proactively. Finally, Amazon CloudWatch Logs allows for deep analysis of application logs to identify errors and anomalies. Together, these services fulfill the requirements of performance monitoring and rapid issue detection.
- A. Correct.
Correct: Amazon CloudWatch Alarms can monitor specific metrics such as response times and error rates and trigger automated actions, such as scaling or notifications.
- B. Incorrect.
Incorrect: Amazon CloudTrail is useful for auditing API calls but does not provide real-time insight into application performance issues.
- C. Correct.
Correct: Amazon CloudWatch Synthetics allows you to simulate user traffic and monitor endpoints for availability and latency, helping to detect performance issues proactively.
- D. Incorrect.
Incorrect: AWS Config monitors configuration compliance but is not intended for real-time application performance monitoring.
- E. Correct.
Correct: Amazon CloudWatch Logs enable you to collect and analyze application logs, which helps in identifying error patterns and diagnosing issues.
- F. Incorrect.
Incorrect: Amazon GuardDuty is a security monitoring service and is not designed for application performance monitoring.
