CLF-C02 Cloud Technology and Services Practice Question
A company uses several AWS services and wants to create a unified monitoring dashboard to track metrics and set alarms. Which AWS service provides this capability?
⚠ Common exam trap
CLF-C02 often tests the confusion between CloudWatch (metrics/alarms), CloudTrail (API audit), and Config (compliance), so candidates must map each service to its exact purpose.

Correct answer & explanation
✓
Amazon CloudWatch
Amazon CloudWatch is AWS's native monitoring and observability service: it collects metrics from AWS resources and applications, supports custom metrics, and provides dashboards, alarms, and logs in one place. A unified dashboard tracking metrics and triggering alarms is exactly CloudWatch's core use case. CloudTrail, Config, and X-Ray serve auditing, compliance, and tracing respectively, not metric dashboards and alarms.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS CloudTrail
Why it's wrong here
AWS CloudTrail is a governance and auditing service that records API activity and user actions across your AWS account, creating an event history for security investigation and compliance evidence. It does not collect numeric performance metrics or maintain real-time dashboards and cannot trigger alarms based on CPU utilization or latency thresholds. For operational monitoring, you need CloudWatch, not CloudTrail.
- ✓
Amazon CloudWatch
Why this is correct
Amazon CloudWatch is the native AWS monitoring service that ingests time-series metrics from more than 70 AWS services and custom applications via the PutMetricData API, then stores them for 15 months. You can build custom dashboards that visualize these metrics, configure alarm rules that trigger on thresholds (e.g., CPU > 80%), and combine with CloudWatch Logs and events to automate responses. This is precisely the dashboarding and alarm functionality required for real-time operational monitoring.
- ✗
AWS Config
Why it's wrong here
AWS Config evaluates resource configurations against compliance rules and records configuration history, enabling you to track drift from desired settings such as 'S3 bucket should have encryption enabled.' It does not collect performance metrics or provide operational dashboards with CPU, memory, or latency graphs, nor does it alarm on metric threshold breaches for live workloads. While it can trigger rules for noncompliant configuration changes, that is fundamentally a configuration compliance feature, not a real-time monitoring service.
- ✗
AWS X-Ray
Why it's wrong here
AWS X-Ray provides distributed tracing to help you identify bottlenecks and errors across microservices by tracking a request as it traverses services, generating a service graph and per-request latency breakdowns. It is designed for debugging and performance analysis at the trace level, not for creating aggregated dashboards of system-wide metrics or launching alerts when a specific metric threshold is crossed. That operational responsibility remains with CloudWatch Alarms and Dashboards, even though X-Ray can send trace summaries to CloudWatch.
