• The included cloud terminal is preconfigured with the gcloud SDK.

• Use the terminal to execute commands and then click Check my progress to verify your work.

Challenge scenario

• Your colleague created a custom VPC network with a compute instance in that network. You have to connect to the compute instance through ssh, but you are facing an error while connecting to the instance. After investigation, you discovered an issue with the firewall. There is no firewall at this movement which allows SSH to this instance.

• Your task is to create a firewall rule so that you can connect to the instance through ssh.
