Port forwarding (Option A) controls traffic through specific ports but doesn't minimize wireless access.

Unused ports (Option B) could refer to physical network ports or firewall settings, unrelated to controlling Wi-Fi access.

Disabling SSID broadcast (Option C) might hide the network name but doesn't secure access.

This process ensures that the software does not negatively impact system functionality, like stopping access to critical resources such as file servers.

End-user acceptance (Option A) ensures that users approve the software, but it wouldn't prevent the issue.

Staff delegation (Option B) relates to who is responsible but doesn't address testing.

Appropriate scoping (Option C) helps in defining the extent of changes but does not replace testing.
