A. Enable MFA for prMleged users
B. Create indMdual IAM users
C. Keep rotating your secure access credentials at regular intervals

Correct Answer:D
It is a recommended approach to avoid using the access and secret access keys of the root account.
Thus, do not download or delete it. Instead make the IAM user as powerful as the root account and use its credentials. The user cannot generate their own access and secret access keys as they are always generated by AWS.
