An instance named shop-vl89f8 is running a web server. Its only security group is monitoring-sg-vl89f8, which the monitoring team relies on; it opens port 9100 to the office. The group web-sg-vl89f8 allows port 80 from anywhere and is not attached.

1. Keep the instance's id in ID and its public IP in IP.

2. Try the page with a three-second limit, then read the exit status:

   sh

   runcopy

   echo $?

3. Give the instance the web group as well. It must keep monitoring-sg-vl89f8.

4. Fetch the page again and read the exit status.
