10. Question 130 · 712 in bank

    A company has teams that have different job roles and responsibilities. The company’s employees often change teams. The company needs to manage permissions for the employees so that the permissions are appropriate for the job responsibilities. Which IAM resource should the company use to meet this requirement with the LEAST operational overhead?

    • AIAM user groups
    • BIAM roles
    • CIAM instance profiles
    • DIAM policies for individual users

    Show answer

    Answer: B

    Explanation

    IAM roles are the most suitable resource for managing permissions in a scenario where employees frequently change teams and have different job roles and responsibilities. IAM roles allow you to define a set of permissions and policies and then assign those roles to users or AWS services as needed. This way, you can grant temporary access based on the user's current job responsibilities, and the users do not have to be directly assigned specific permissions. IAM user groups (option A) are typically used to simplify the management of permissions for sets of users who share common job responsibilities. However, roles provide more flexibility in dynamic scenarios where users move between teams.
