Full question →mediummultiple choiceObjective-mapped
A company uses AWS Organizations with consolidated billing across multiple member accounts. The finance team requires that only the management account (payer account) can view and modify payment methods and receive invoices. Member accounts must be prevented from accessing billing and payment information in the AWS Billing and Cost Management console. Which AWS feature should be configured to enforce this restriction?
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
Enable all features in AWS Organizations, including consolidated billing.
Enabling all features is a prerequisite for using Service Control Policies, but this step alone does not restrict member account access to billing pages. Additional SCP configuration is required.
B
Best answer
Apply a Service Control Policy (SCP) to deny billing-related actions for all member accounts.
An SCP can explicitly deny actions like 'aws-portal:ViewBilling' and 'aws-portal:ModifyBilling' for member accounts. This prevents users in those accounts from accessing billing information, leaving full control to the management account.
C
Distractor review
Enable AWS CloudTrail to log billing events for all accounts.
AWS CloudTrail records API calls for auditing purposes, including billing events, but it does not prevent member accounts from accessing billing pages. It provides visibility, not restriction.
D
Distractor review
Configure AWS Cost Explorer to grant cross-account access only to the management account.
AWS Cost Explorer allows viewing of cost and usage data, but it does not restrict access to the billing console or payment methods. It is not a mechanism to prevent member accounts from modifying billing settings.
Common exam trap
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Technical deep dive
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.

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?
Standard ACLs match source addresses.
What is the correct answer to this question?
The correct answer is: Apply a Service Control Policy (SCP) to deny billing-related actions for all member accounts. — AWS Organizations allows you to centrally govern your environment. Service Control Policies (SCPs) are used to manage permissions for member accounts. By applying an SCP that denies actions such as 'aws-portal:ModifyBilling' and 'aws-portal:ViewBilling', the management account can restrict member accounts from accessing billing information. This ensures that only the management account retains full billing control. Option B is correct. Option A (enabling all features) is necessary for SCPs but does not itself enforce the restriction. Option C (CloudTrail) is used for auditing, not for preventing access. Option D (Cost Explorer) provides cost data but does not restrict billing console access.
