Q14 — AWS SOA-C02 Ch.1

Question 14 of 100 | ← Chapter 1

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?

• A. The IAM password is incorrect.
• B. The server certificate is missing.
• C. The SSH key pair is incorrect.
• D. There is no access key. ✓

Correct Answer: D. There is no access key.

Explanation

AWS CLI的身份验证依赖访问密钥（Access Key ID和Secret Access Key），而非IAM用户密码或SSH密钥。AWS官方文档明确指出，使用AWS CLI时必须配置有效的访问密钥。选项A的IAM密码用于控制台登录，与CLI无关。选项B的服务器证书问题通常影响SSL连接，不影响认证流程。选项C的SSH密钥用于EC2实例访问，不作用于API调用。选项D正确，因为未配置访问密钥会导致AWS CLI无法完成身份验证。
