Any Company’s security team does not allow creation of fixed long-term AWS Access Key ID and Secret Access Key for API access.

How would you install the MGN agent on the source servers for a successful migration using MGN?

1. You need to create an IAM role with AWSApplicationMigrationAgentInstallationPolicy policy and generate temporary credentials using AWS STS (Secure token service).
2. Inform the security team that AWS IAM fixed long-term security credentials are secure and can be used with MGN.
3. Inform the security team that MGN is a very secure service and hence an exemption can be made on fixed long-term key requirements.
4. Create an IAM user and set a highly secure password for it. Use these credentials during agent installation.
   
   ANS: You need to create an IAM role with AWSApplicationMigrationAgentInstallationPolicy policy and generate temporary credentials using AWS STS (Secure token service).
