- A
Attach an inline policy to each of the 10 IAM users individually
Why wrong: Attaching individual inline policies to each user is repetitive and hard to maintain. If the permissions need to change, each user's policy must be updated separately.
- B
Create an IAM group, attach the required policies to the group, and add all 10 users to the group
IAM groups are specifically designed for this purpose. Assign policies once to the group, add users to the group, and all users inherit the permissions. Future permission changes only need to be made to the group.
- C
Create one IAM user account and share the credentials with all 10 developers
Why wrong: Sharing credentials violates AWS best practices. It makes auditing impossible (you cannot tell which developer made an action), and if the credentials are compromised, all access must be revoked.
- D
Grant the developers root account access with MFA enabled
Why wrong: Using the root account for daily developer access is a critical security anti-pattern. The root account should be locked away and used only for specific account-level tasks.
Quick Answer
The answer is to create an IAM group, attach the required policies to the group, and add all 10 users to the group. This is the AWS best practice for assigning permissions because IAM groups act as a central container for permissions; any policy attached to the group is automatically inherited by every member, making it far more efficient than attaching policies individually to each user. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of the principle of least privilege and the IAM group resource as a management tool—a common trap is choosing to attach policies directly to each user, which violates the "efficient and scalable" best practice. Remember the memory tip: "Group the users, group the policies" — think of an IAM group as a team jersey that gives every player the same permissions instantly.
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 hires 10 new developers and needs to assign them identical AWS permissions — read access to S3 and the ability to launch EC2 instances. What is the AWS best practice for assigning these permissions efficiently?

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
Create an IAM group, attach the required policies to the group, and add all 10 users to the group
IAM groups allow administrators to assign permissions to multiple users at once. By creating a 'Developers' group with the required policies and adding all 10 users to it, permissions are managed centrally. Adding a policy to the group affects all members simultaneously.
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
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.
Detailed technical explanation
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.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
