One-line summary
Provide AWS best-practice recommendations for cost, performance, security, fault tolerance, and quotas.
Core capabilities and use cases
- Runs predefined checks and highlights results by severity.
- Common areas are cost optimization, performance, security, fault tolerance, and service limits.
- Findings can include idle resources, exposed ports, missing root MFA, insufficient backups, or quota pressure.
- Recommendations require business review and are not normally automatic remediation.
- Available checks and automation depth can vary by support plan and feature.
Exam focus and common pitfalls
- Choose Trusted Advisor when a question spans several best-practice categories.
- Config evaluates custom or managed compliance rules; Inspector scans software vulnerabilities; Compute Optimizer recommends sizing.
- Service Quotas manages quota values and increase requests, while Trusted Advisor can warn about pressure.
Key takeaway
Think of Trusted Advisor as an AWS best-practice health check that recommends, rather than automatically fixes.
Update: check scope and automation boundaries
- Trusted Advisor provides account- and resource-level best-practice checks across cost, performance, security, fault tolerance, service limits, and operational excellence.
- Available checks and refresh capabilities depend on the support plan and API permissions; do not assume every account has every check in real time.
- Trusted Advisor supplies findings, Well-Architected reviews a workload, and Config evaluates configuration compliance. They are complementary.
