Web Server Security task failed

Web Server Security task failed with description:
web server is not exposing apache version on App Server 3.

But in task description there was requirement for App Server 3 not to show apache version.

I added 'ServerSignature Off ’ option in /etc/httpd/conf/httpd.conf file.

What is wrong?

You need to add below 2 lines in /etc/httpd/httpd.conf
ServerToken Prod
ServerSignature Off

After that you need to restart the httpd service.

Thank you.
Hope it would help if I get this task again.
