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?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

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.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    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.

    When this WOULD be correct

    A question where the policy must restrict EC2 instance launches to only the us-east-1 region, using the aws:RequestedRegion condition key in an IAM policy.

  • ✓

    aws:SourceIp condition key

    Why this is correct

    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.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    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.

    When this WOULD be correct

    A company wants to ensure that only IAM principals belonging to a specific AWS Organization can access resources. For example, an IAM policy that allows EC2 actions only if aws:PrincipalOrgID matches 'o-1234567890'.

  • ✗

    aws:MultiFactorAuthPresent condition key

    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.

    When this WOULD be correct

    A company's security policy requires that all API calls to terminate EC2 instances must be made by users who have authenticated with MFA. The administrator uses aws:MultiFactorAuthPresent condition key to enforce this in the IAM policy.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.

✓aws:SourceIp condition keyCorrect answer▾

Why this is correct

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.

✗aws:RequestedRegion condition keyWrong answer — click to see why▾

Why this is wrong here

The aws:RequestedRegion condition key restricts actions to specific AWS regions, not IP addresses. SSH connections to EC2 instances are controlled by network-level conditions like source IP, not region.

★ When this WOULD be the correct answer

A question where the policy must restrict EC2 instance launches to only the us-east-1 region, using the aws:RequestedRegion condition key in an IAM policy.

Why candidates choose this

Candidates may confuse 'region' with 'IP range' because both involve geographic or network boundaries, or they might think restricting by region indirectly controls network access.

✗aws:PrincipalOrgID condition keyWrong answer — click to see why▾

Why this is wrong here

The aws:PrincipalOrgID condition key is used to restrict access based on the AWS Organization ID of the principal, not the IP address of the request. It does not control network source IP.

★ When this WOULD be the correct answer

A company wants to ensure that only IAM principals belonging to a specific AWS Organization can access resources. For example, an IAM policy that allows EC2 actions only if aws:PrincipalOrgID matches 'o-1234567890'.

Why candidates choose this

Candidates may confuse organizational identity with network identity, or think that 'PrincipalOrgID' can be used to restrict access to corporate network IPs because the corporate network is part of the organization.

✗aws:MultiFactorAuthPresent condition keyWrong answer — click to see why▾

Why this is wrong here

The aws:MultiFactorAuthPresent condition key checks whether multi-factor authentication was used, not the IP address of the request. This question specifically requires restricting SSH connections based on IP range, not MFA status.

★ When this WOULD be the correct answer

A company's security policy requires that all API calls to terminate EC2 instances must be made by users who have authenticated with MFA. The administrator uses aws:MultiFactorAuthPresent condition key to enforce this in the IAM policy.

Why candidates choose this

Candidates may confuse MFA as a common security control and think it can be used to restrict access based on network location, or they may misread the question as requiring authentication strength rather than IP restriction.

Analysis generated from the official CLF-C02blueprint and verified against question context. The “when correct” sections are what AI assistants cite when candidates ask “what’s the difference between these options?”

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.
