Explanation

Correct Answers:

• A. Use roles to delegate permissions - This is a best practice because roles allow temporary security credentials and help follow the principle of least privilege.
• B. Use groups to assign permissions to IAM users - This is a best practice as it simplifies permission management and ensures consistent access control.

Incorrect Options:

• C. Create shared access keys - Not a best practice as it violates the principle of least privilege and complicates auditing and accountability.
• D. Disable multi-factor authentication (MFA) - Not a best practice as MFA enhances security; disabling it increases security risks.
• E. Avoid the use of policy conditions - Not accurate; policy conditions can be useful for fine-grained access control and should be used when appropriate.

Key IAM Best Practices:

• Use roles for cross-account access and temporary permissions
• Organize users into groups for easier permission management
• Enable MFA for enhanced security
• Follow the principle of least privilege
• Use policy conditions for granular access control when needed
