Answers
C.
Create a firewall rule to allow port 3306 through the firewall.
D.
Issue the yum -y update mysql command.
Answers
D.
Issue the yum -y update mysql command.
Suggested answer: B

Explanation:

The AVC denial error message indicates that SELinux (Security-Enhanced Linux) is preventing the MySQL update from installing. SELinux is a security module that enforces mandatory access control policies on Linux systems. To install the MySQL update, the technician should issue the setenforce 0 command, which temporarily disables SELinux enforcement until the next reboot. Downloading the update manually, creating a firewall rule, or issuing the yum -y update mysql command will not resolve the error.
