Why might you be able to SSH into an instance from another instance in the same VPC by its internal IP address but not its external IP address?
A
The outgoing instance lacks the necessary permissions granted to its service account.
B
The external IP address is not enabled.
C
The firewall rule permitting SSH is limited to the internal VPC network.
D
The instance you're trying to access has an ephemeral address rather than a reserved one.
