How to configure Apache to serve HTTP version 2?

The configuration file of Apache already has the following:

LoadModule http2_module modules/mod_http2.so

and...

<IfModule mod_http2.c>
    Protocols h2 h2c http/1.1
</IfModule>

HTTPS is working too using certificate issued from Let's Encrypt.

However, when I try to request a resource say:

https://h2.example.com/index.html

Apache is still serving it with the protocol http/1.1 and still not h2.

One thing I noticed was that the response for the resource just have the following header:

Server: Apache/2.4.41 () OpenSSL/1.0.2k-fips

instead of the working ones with:

Server: Apache
Upgrade: h2,h2c

Check the error log. – Michael Hampton Sep 23 '20 at 02:56
@MichaelHampton an error log says: `[http2:warn] [pid 12345] AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive.` What did I miss? – Abel Melquiades Callejo Sep 23 '20 at 03:12
You forgot to switch to the event MPM. – Michael Hampton Sep 23 '20 at 04:43
