Troubleshooting basic network connectivity issues is an important skill. This troubleshooting scenario is an opportunity to assess skills in this area.
Our scenario is this: a junior administrator has deployed a VPC and instances but there are a few things wrong. `Instance3` is not able to connect to the internet and, and the junior admin can’t determine why.
Being a senior administrator, it’s your responsibility to troubleshoot the issue and ensure that the instance has connectivity to the internet, so that you can ping and log into the instance with SSH.
Successfully complete this lab by achieving the following learning objectives:
- Determine why the instance cannot connect to the internet
Troubleshoot connectivity for
Instance3and resolve the issue.
- Identify the second issue preventing the instance from connecting to the internet
Identify and fix the issues that are preventing the instance from connecting to the internet. Once they’re resolved, connect to the instance using SSH to verify connectivity. Use the
cloud_userusername and the password identified on the lab credentials page to login:
ssh cloud_user@< IPADDRESS >
