Which configuration file would be edited to change the default options for outbound SSH sessions?
Correct Answer: D
The /etc/ssh/ssh_config file is the global configuration file for the OpenSSH client. It contains the default values for the options that apply to all outbound SSH sessions initiated from the system. The options in this file can be overridden by the user's configuration file (~/.ssh/config) or by command-line arguments. The /etc/ssh/sshd_config file is the configuration file for the OpenSSH server, and it does not affect outbound SSH sessions. The other options are not valid configuration files for OpenSSH.
