An administrator needs to modify the file context type for a custom directory, /data/webapp, to match the type used by web content in an SELinux environment. Which command should they use to achieve this, ensuring the default policy is maintained for consistency?
chcon -t httpd_sys_content_t /data/webapp
restorecon -v /data/webapp
semanage boolean -m --on httpd_sys_content_t '/data/webapp'
semanage fcontext -a -t httpd_sys_content_t '/data/webapp(/.*)?'
