- B. to prevent any transaction experiencing a deadlock

After rebooting the host, you attempt to start the mysqld service. You get the following error:
Can't start the server: Bind on TCP/IP port: Address already in use
What is the most likely cause of this error?
- A. You failed to specify the port number 3306 to the command to start the server, so it is defaulting to port
80, which is in use by the built-in web server. - B. The network service process in the server is frozen, so all TCP/IP connections are paused and cannot be reused.
- C. The /etc/hosts file does not have a valid IP entry for mysqld localhost, so it is binding to 127.0.0.1, which is already in use.
- D. The mysql service has already been started on the same port.
- E. The mysql.sock file in the MySQL /tmp directory was not removed after the reboot, so mysqld still thinks there is an active server running.
Correct Answer: E 🗳️
