Exam NCP-MCA Topic 5 Question 25 Discussion

The error "Connection refused" can occur due to several reasons but in the context of running a script through Calm on VM, it is most likely caused by firewall restrictions or insufficient permissions. Option A suggests that the VM port is not allowed by the firewall, meaning that the firewall settings are preventing the connection. This could be because specific ports needed for the script to run are being blocked. Option B indicates that the credentials have insufficient permissions, meaning that the user or system trying to execute the script does not have the necessary permissions to establish a connection. Option C is unlikely because the VM should be ready before the script is executed. Option D is possible but not specific enough to explain the connection issue.
