Which actions represent best practices for using AWS IAM? (choose two)

Implementing Multi-Factor Authentication (MFA) is a vital best practice for using AWS Identity and Access Management (IAM) because it adds an additional layer of security to the login process. By requiring not just a password but also a second form of verification, such as a code from a mobile app or a physical token, MFA helps to protect user accounts from unauthorized access. This becomes especially important in cloud environments where sensitive data and resources are at risk. Even if a password is compromised, MFA can significantly reduce the likelihood of unauthorized access.

Additionally, granting least privilege access is another best practice. This principle means that users are given the minimum level of access required to perform their jobs. By limiting permissions, you can reduce the risk of accidental or malicious misuse of AWS resources. This means regularly reviewing and adjusting IAM policies, thereby ensuring users only have the privileges necessary to fulfill their roles, which in turn helps to enhance overall security and minimize potential vulnerabilities.

Choosing these actions promotes a secure environment in AWS by enforcing robust authentication measures and adhering to security principles that limit exposure and risk.
