correct apache2 virtual host config

I was a dummy and started making changes to the 000-default-ls-ssl.conf file without a back up.

Here is what I think the file should be with the actual domain name changed to example.com.

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        <Directory /var/www/html/>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem 
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem 
Include /etc/letsencrypt/options-ssl-apache.conf 
ServerName example.com 
</VirtualHost> 

If I run apachectl -t as a not root user with SUDO it says that there is a snytax error in the line with the SSLCertifcateFile. It also says that the fullchain.pem file does not exist.

But if I run the same command as root it says syntax is ok?

1st is the config ok? 2nd should the sudo user and root test the config the same?

One last question. I have been reading that it is better to place the items that are normally in the hraccess file in the apache conf since it makes apache faster??? What does the experts on here think?
