aws:RequestedRegion condition key
Why wrong: The aws:RequestedRegion condition key is used to specify the AWS Regions from which a request must originate, not the source IP address.
- B
aws:SourceIp condition key
The aws:SourceIp condition key is the correct IAM policy element to restrict requests to specific source IP address ranges, such as a corporate network.

Why wrong: The aws:PrincipalOrgID condition key is used to restrict access to principals that belong to a specific AWS Organizations organization, not to enforce IP restrictions.
- D
aws:MultiFactorAuthPresent condition key
Why wrong: The aws:MultiFactorAuthPresent condition key is used to require that the request was authenticated with a multi-factor authentication (MFA) device, not to restrict source IP addresses.
Quick Answer
The answer is the aws:SourceIp condition key. This is correct because the aws:SourceIp key allows you to specify an allowed IP address range in an IAM policy’s condition block, enforcing that API calls—such as those launching or managing EC2 instances—must originate from a particular source IP, like your corporate network’s 203.0.113.0/24 range. On the AWS Certified Cloud Practitioner CLF-C02 exam, this tests your understanding of IAM policy conditions and network security controls, often appearing in scenario-based questions about restricting SSH access to EC2 instances. A common trap is confusing aws:SourceIp (which checks the caller’s IP) with a security group rule (which controls traffic to the instance itself); remember, IAM policies govern who can make API calls, not the actual network traffic flow. Memory tip: think “SourceIp = Source of the API call, not the destination of the SSH session.”
CLF-C02 Security and Compliance Practice Question
This CLF-C02 practice question tests your understanding of security and compliance. 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 has a security policy that requires all SSH connections to Amazon EC2 instances to originate from the company's corporate network IP range (203.0.113.0/24). An administrator is creating an IAM policy to enforce this restriction. Which IAM policy element should the administrator use to specify the allowed IP address range?

Correct answer & explanation
aws:SourceIp condition key
The aws:SourceIp condition key is used in IAM policies to restrict access based on the requester's IP address. Since the security policy requires SSH connections to EC2 instances to originate only from the corporate network IP range (203.0.113.0/24), the administrator should use aws:SourceIp in a condition block to enforce this restriction. This key evaluates the source IP address of the API caller, not the destination of the traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
aws:RequestedRegion condition key
Why it's wrong here
The aws:RequestedRegion condition key is used to specify the AWS Regions from which a request must originate, not the source IP address.

aws:PrincipalOrgID condition key
Why it's wrong here
The aws:PrincipalOrgID condition key is used to restrict access to principals that belong to a specific AWS Organizations organization, not to enforce IP restrictions.

Why it's wrong here
The aws:MultiFactorAuthPresent condition key is used to require that the request was authenticated with a multi-factor authentication (MFA) device, not to restrict source IP addresses.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse IAM policy conditions (which control API access) with network-level controls (like security groups), leading them to incorrectly think aws:SourceIp can directly restrict SSH traffic to the instance rather than the API calls that manage it.
Detailed technical explanation
How to think about this question
The aws:SourceIp condition key works with the source IP address of the request as seen by AWS, which may differ from the actual client IP if the request passes through a proxy or VPN. For SSH connections to EC2 instances, the IAM policy controls API calls (e.g., ec2:StartInstances or ec2:DescribeInstances), not the SSH protocol itself; network-level SSH access must be enforced via security group rules or network ACLs. This distinction is critical because IAM policies govern AWS API access, while security groups control network traffic to the instance.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
