"named" service validation

I’ve taken Linux test - level 1 on KodeKloud Engineer, in which the last task was to install bind package on all app servers and start/enable its service(named).

According to me I’ve installed bind and started/enabled the service on all the app servers. But the test failed saying - service ‘named’ is not running on app server 2.
systemctl status named shows running and enabled on app server 2 in the attached screenshot.

Is it a bug? or am I missing something?

Commands that I ran on all 3 app servers:

  1. sudo yum install bind - to install bind
  2. sudo systemctl start named - to start the service
  3. sudo systemctl enable named - to enable the service
