Refer to the exhibit. A network administrator configures command authorization for the admm5 user. What is the admin5 user able to do on HQ_Router after this configuration?

If command authorization is configured but no specific commands are explicitly permitted for a user like 'admin5' within the policy, the user will be denied access to execute any configuration commands by default, effectively blocking all changes.

Adding subinterfaces is a configuration command, and without explicit authorization for this action, the user would be denied permission to perform it.

Completing all configurations implies full administrative access, which would require specific and broad authorization, contrary to a scenario where authorization might restrict actions.

Setting an IP address is a specific configuration command; without explicit authorization for interface configuration, the user would be unable to perform this task.
