What service will help you monitor for sudden reliability issues?

• A. Amazon Care
• B. Amazon CloudWatch
• C. AWS Shield
• D. AWS WAF

Answer: (B)

The correct service for monitoring sudden reliability issues is Amazon CloudWatch. This service allows you to observe and analyze system performance in real-time, providing metrics that can highlight changes in performance and reliability. With CloudWatch, you can set up alarms for specific metrics related to your applications and resources, which helps you detect problems almost immediately. For example, if your application experiences an unexpected spike in latency or error rates, CloudWatch can notify you, enabling prompt investigation and remedial action. Additionally, CloudWatch integrates well with many other AWS services, giving you comprehensive visibility across your entire AWS environment. This makes it an essential tool for maintaining the reliability of your applications and infrastructure. Other services mentioned, such as AWS Shield and AWS WAF, are more focused on security—protecting applications from DDoS attacks and filtering out malicious web traffic, respectively. Amazon Care is unrelated, as it is focused on healthcare services rather than cloud infrastructure monitoring. Thus, CloudWatch stands out as the most effective option for monitoring reliability issues.
