The answer is creating an IAM role with a trust policy for EC2. This action is correct because AWS IAM allows you to define roles that grant temporary credentials to AWS services like EC2, with a trust policy specifying which entities (such as the EC2 service) can assume the role. On the AWS Certified Security Specialty SCS-C02 exam, this tests your understanding of IAM’s core capabilities beyond user management—specifically, how roles enable secure, temporary access for workloads without embedding long-term keys. A common trap is confusing IAM’s ability to create roles with its inability to directly manage external identity provider tokens or modify service-level resource policies; remember, IAM governs identities and permissions, not the services themselves. For a memory tip, think “roles for resources, policies for people”—IAM roles are designed for AWS services and federated access, while user policies handle human credentials.
SCS-C02 Identity and Access Management Practice Question
This SCS-C02 practice question tests your understanding of identity and access management. 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.
Which TWO actions can be performed using AWS IAM? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Define a password policy for IAM users
Option C is correct because AWS IAM allows you to define a password policy for IAM users, which enforces complexity requirements, rotation periods, and reuse prevention. This is a core IAM feature that helps secure user credentials without relying on external identity providers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Change the instance type of an RDS database
Why it's wrong here
This is an RDS operation, not IAM.
✗
Create a CloudFront distribution
Why it's wrong here
CloudFront distributions are created via CloudFront service.

VPC peering is managed via Amazon VPC.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse IAM's authorization capabilities (granting permissions) with the ability to directly perform resource operations, leading them to select options like A, B, or E that are actual AWS actions but are not performed by IAM itself.
Detailed technical explanation
How to think about this question
IAM password policies are defined at the account level and apply to all IAM users; they can enforce parameters such as minimum password length (default 6, max 128), require at least one uppercase letter, and prevent password reuse (up to 24 previous passwords). This policy is stored as a resource in the account and can be retrieved via the GetAccountPasswordPolicy API, which returns the policy document as a JSON structure. In real-world scenarios, organizations often combine IAM password policies with AWS Config rules to detect non-compliant policies automatically.

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.
