AWS Certified SysOps Administrator – Associate (legacy) — Question 117

A user is trying to connect to a running EC2 instance using SSH. However, the user gets a connection time out error. Which of the below mentioned options is not a possible reason for rejection?

Answer options

• A. The access key to connect to the instance is wrong
• B. The security group is not configured properly
• C. The private key used to launch the instance is not correct
• D. The instance CPU is heavily loaded

Correct answer: A

Explanation

The correct answer is A because a connection timeout typically indicates network issues rather than problems with the access key. Options B, C, and D all relate to configurations or conditions that could prevent a successful SSH connection, such as incorrect security group settings, a wrong private key, or resource exhaustion on the instance.
