DOP-C02 Question 336
Select 3Your organization runs a mission-critical application on AWS. Recently, you noticed degraded performance during a specific time window. As a DevOps engineer, you want to identify if the issue was caused by an AWS service disruption and manage the incident effectively. Which combination of AWS services can you use to identify the root cause and streamline the resolution process?
- A
AWS Health to check service disruptions and scheduled maintenance
- B
Amazon CloudWatch to monitor application metrics and logs
- C
AWS Systems Manager OpsCenter to centralize and manage operational issues
- D
AWS Trusted Advisor to optimize resources and identify potential cost savings
- E
AWS Config to track historical changes to your infrastructure
Show answer and explanation
Correct answers: A, B, C
Explanation
To diagnose and resolve the degraded performance issue, you need tools that help identify AWS service disruptions (AWS Health), monitor application-specific metrics (Amazon CloudWatch), and manage operational issues efficiently (AWS Systems Manager OpsCenter). Trusted Advisor and AWS Config do not directly assist in identifying or resolving service disruptions, making the first three options the most appropriate combination.
- A. Correct.
AWS Health provides information about service disruptions, outages, and scheduled maintenance that could impact your applications. It is critical for identifying if an AWS service issue caused the degraded performance.
- B. Correct.
Amazon CloudWatch allows you to monitor application metrics, logs, and events. This helps in correlating performance issues with application-specific data, aiding root cause identification.
- C. Correct.
AWS Systems Manager OpsCenter centralizes operational issues, enabling you to track, investigate, and resolve incidents effectively. It integrates with AWS Health and CloudWatch to streamline incident management.
- D. Incorrect.
AWS Trusted Advisor is primarily a recommendation tool for cost optimization, security, fault tolerance, and performance improvements. While useful, it does not directly address service health or incident resolution.
- E. Incorrect.
AWS Config is used to track configuration changes to AWS resources, which is less relevant for identifying AWS service disruptions or managing active incidents.
