A Linux systems administrator is setting up a new web server and getting 404 - NOT FOUND errors while trying to access the web server pages from the browser. While working on the diagnosis of this issue, the Linux systems administrator executes the following commands: Which of the following commands will BEST resolve this issue?

The command restorecon -R -v /var/www/html will best resolve the issue. The issue is caused by the

incorrect SELinux context of the web server files under the /var/www/html directory. The output of ls

-Z /var/www/html shows that the files have the type user_home_t, which is not allowed for web

content. The command restorecon restores the default SELinux context of files based on the policy

rules. The options -R and -v are used to apply the command recursively and verbosely. This command

will change the type of the files to httpd_sys_content_t, which is the correct type for web content.

This will allow the web server to access the files and serve the pages to the browser. The other

options are incorrect because they either disable SELinux entirely (sed -i

's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config or setenforce 0), which is not a good

security practice, or enable an unnecessary boolean (setsebool -P httpd_can_network_connect_db

on), which is not related to the issue. : CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter
