AWS Certified SysOps Administrator – Associate (legacy) — Question 48

After launching a new Amazon EC2 instance from a Microsoft Windows 2012 Amazon Machine Image (AMI), the SysOps Administrator is unable to connect to the instance using Remote Desktop Protocol (RDP). The instance is also unreachable. As part of troubleshooting, the Administrator deploys a second instance from a different AMI using the same configuration and is able to connect to the instance.
What should be the next logical step in troubleshooting the first instance?

Answer options

• A. Use AWS Trusted Advisor to gather operating system log files for analysis.
• B. Use VPC Flow Logs to gather operating system log files for analysis.
• C. Use EC2Rescue to gather operating system log files for analysis.
• D. Use Amazon Inspector to gather operating system log files for analysis.

Correct answer: C

Explanation

The correct answer is C, as EC2Rescue is specifically designed to assist with troubleshooting and diagnosing issues on Windows EC2 instances, including problems with connectivity. The other options, while useful for different purposes, do not provide the targeted analysis needed for the operating system issues affecting the initial instance.
