- A
Amazon Inspector
Why wrong: Inspector performs security assessments of EC2 instances and container images for vulnerabilities. It does not provide the broad five-category analysis across cost, performance, fault tolerance, and service limits.
- B
AWS Config
Why wrong: Config tracks resource configuration changes and evaluates compliance against rules. It does not provide holistic recommendations across cost, performance, security, fault tolerance, and service limits.
- C
AWS Trusted Advisor
Trusted Advisor inspects the AWS account against a set of best practices and provides recommendations across cost optimisation, performance, security, fault tolerance, and service quotas. Higher support tiers unlock more checks.
- D
Amazon CloudWatch
Why wrong: CloudWatch monitors metrics and logs. It does not provide the advisory recommendations across the five categories that Trusted Advisor provides.
Quick Answer
The answer is AWS Trusted Advisor. This service is the correct choice because it functions as an automated tool that continuously analyzes your AWS account and delivers recommendations across the five key categories: cost optimization, performance, security, fault tolerance, and service limits, all based on AWS best practices. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of which service provides a holistic, single-pane-of-glass assessment for account health, often appearing as a straightforward recall item. A common trap is confusing Trusted Advisor with AWS Compute Optimizer (which focuses only on cost and performance for compute resources) or AWS Security Hub (which covers only security and compliance). To remember it, think of Trusted Advisor as your personal AWS consultant—it checks all five pillars of the Well-Architected Framework plus your service limits, giving you a complete health check in one place.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants an automated tool that analyses their AWS account and provides recommendations across five categories: cost optimisation, performance, security, fault tolerance, and service limits. Which AWS service provides this analysis?

Correct answer & explanation
AWS Trusted Advisor
AWS Trusted Advisor is the correct service because it is specifically designed to analyze an AWS account and provide recommendations across the five categories listed: cost optimization, performance, security, fault tolerance, and service limits. It evaluates resources against AWS best practices and offers actionable guidance, making it the only service that covers all these domains in a single, automated tool.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Trusted Advisor with AWS Config or Amazon Inspector, because they all involve analysis or checks, but only Trusted Advisor provides the specific five-category recommendation framework described in the question.
Detailed technical explanation
How to think about this question
AWS Trusted Advisor uses a set of checks that run against your account's resources, leveraging AWS's internal best practices and thresholds (e.g., for service limits, it checks usage against the default limits like 100 EC2 instances per region). It provides a dashboard with green (no issues), yellow (recommended investigation), and red (action recommended) indicators, and for Business and Enterprise support plans, it offers programmatic access via the AWS Support API to retrieve check results. A real-world scenario is a company using Trusted Advisor to identify underutilized EC2 instances (cost optimization) and then rightsizing them, while also checking for security groups with unrestricted access (security).
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
