A cloud operations team needs to implement a monitoring solution for a microservices architecture. The solution must provide centralized logging, metrics, and alerting, and must be able to correlate data from multiple services. Which THREE of the following components should the team include?
⚠ Common exam trap
CompTIA often tests the distinction between specialized tools (SIEM, APM) and the core triad of centralized logging, metrics, and correlation/alerting, leading candidates to over-select security or tracing tools that do not fulfill the requirement for correlating data from multiple services at the log and metric level.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A centralized logging system (e.g., ELK stack).
A centralized logging system like the ELK stack (Elasticsearch, Logstash, Kibana) aggregates logs from all microservices into a single searchable repository. This enables the team to correlate events across services by timestamp and metadata, which is essential for debugging distributed transactions and identifying root causes of failures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A security information and event management (SIEM) system.
Why it's wrong here
SIEM is security-focused; general operations monitoring doesn't require it.
- ✓
A centralized logging system (e.g., ELK stack).
Why this is correct
Centralized logging aggregates logs from all services.
- ✓
A correlation engine and alerting system (e.g., event correlation).
Why this is correct
Correlation engine links logs and metrics for better diagnosis.
- ✓
A metrics collection agent and dashboard (e.g., Prometheus+Grafana).
Why this is correct
Metrics aggregation provides system performance data.
- ✗
An application performance monitoring (APM) tool.
Why it's wrong here
APM is useful but not essential for correlation; logs and metrics suffice.
