A company runs a critical application on Amazon EC2 instances in a specific Availability Zone. The operations team wants to be notified immediately if AWS experiences a service disruption that could affect their instances. They also want a personalized view of the impact of AWS service events on their specific AWS resources. Which AWS tool should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
AWS Trusted Advisor
AWS Trusted Advisor provides recommendations on best practices (cost, performance, security, fault tolerance) but does not deliver real-time alerts about service disruptions affecting your specific resources.
B
Best answer
AWS Personal Health Dashboard
This tool delivers a personalized view of AWS service events that impact your account and resources. It can send immediate notifications via Amazon EventBridge, SNS, or email, and provides a dashboard specific to your resources.
C
Distractor review
AWS Service Health Dashboard
The Service Health Dashboard shows the global status of all AWS services, but it is not personalized to your account or resources. It does not provide targeted notifications for events affecting your specific EC2 instances.
D
Distractor review
AWS CloudTrail
AWS CloudTrail logs API calls made in your account for auditing and compliance. It does not monitor or alert on AWS service health events that may disrupt your running resources.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: AWS Personal Health Dashboard — The AWS Personal Health Dashboard (also known as AWS Health) provides a personalized view of the health of AWS services that affect your account. It alerts you to events such as EC2 instance failures, scheduled maintenance, or Availability Zone impairments that impact your specific resources. Notifications can be sent via Amazon EventBridge, Amazon SNS, or email. In contrast, the AWS Service Health Dashboard provides the overall status of all AWS services globally without filtering by your account's resources. AWS Trusted Advisor offers best-practice recommendations for cost optimization, performance, security, and fault tolerance. AWS CloudTrail records API activity for auditing purposes. For timely, account-specific operational alerts, the Personal Health Dashboard is the correct choice.
