A SysOps administrator is unable to authenticate an AWS CLI call to an AWS service.
Which of the following is the cause of this issue?
The IAM password is incorrect.
The server certificate is missing.
The SSH key pair is incorrect.
There is no access key.
Explanations:
The IAM password is used for AWS Management Console login, not for CLI access. The CLI uses access keys for authentication.
The server certificate is not required for AWS CLI authentication. It is typically used for secure communications (e.g., SSL/TLS) rather than API calls.
SSH key pairs are used for EC2 instance access, not for authenticating AWS CLI commands.
AWS CLI authentication requires an access key (Access Key ID and Secret Access Key). Without an access key, authentication cannot occur.
