Troubleshooting
Apache returns 403 Forbidden for files in /srv/web, even though the Unix permissions allow reading. ls -Z shows the files are labelled default_t. What fixes this persistently?
chmod -R 777 /srv/web so that every user and process, including httpd, has full access
semanage fcontext -a -t httpd_sys_content_t "/srv/web(/.*)?" then restorecon -Rv /srv/web
setenforce 0 and leave the server in permissive mode
chcon -R -t httpd_sys_content_t /srv/web only
B
SELinux blocks httpd from reading files labelled default_t. Defining the file-context rule with semanage and applying it with restorecon gives the files the web-content label, and the label survives future relabels. chmod 777 is insecure and does not change the label, permissive mode switches the protection off, and a chcon change is reverted by the next relabel.

About this course

These practice tests are for Linux system administrators, DevOps engineers and IT professionals preparing for the CompTIA Linux+ (XK0-006) exam, the V8 exam that replaced XK0-005 in January 2026. They are also a fast way to move from XK0-005 study material to the new exam.

You get 13 full-length practice tests with 90 questions each, 1,170 questions in total, sized like the real exam, including two Exam Mode tests. Every question explains why the right answer is right and why the others are wrong, includes a hint, and is mapped to one of the five official XK0-006 domains. The series was rebuilt for XK0-006: every answer key was re-checked, duplicates and questions on retired tools such as netstat, ifconfig and SysVinit were removed or updated, and 392 new questions cover topics the new exam adds, such as responsible AI use, Python basics, OpenTofu, GitOps, monitoring and SLOs.
